Syncfusion Blazor Pivot Table

Syncfusion Blazor Pivot Table

The Syncfusion Blazor Pivot Table (SfPivotView) is a powerful multi-dimensional data analysis component that enables users to organize, summarize, and visualize data across row, column, value, and filter axes — similar to Excel pivot tables. It supports relational data (JSON/IEnumerable) and OLAP cubes, with interactive runtime controls including a Field List and Grouping Bar.

⚠️ Important: Always verify API class names, properties, and method signatures by consulting the reference files in this skill (references/*.md). These are maintained with verified, working examples. Do not assume API details from other sources.

⚠️ Security Warning: Data Source Validation

CRITICAL SECURITY NOTICE: When implementing pivot tables, always use trusted data sources. Never fetch or bind data from untrusted or user-provided URLs without proper validation and sanitization.

Security Best Practices:

1. Use Local Data: Prefer local, in-memory data sources for maximum security 2. Validate Remote Sources: Only connect to authenticated and authorized API endpoints under your control 3. Sanitize User Input: Never allow users to specify arbitrary URLs or data sources 4. Implement Authentication: Always use authentication headers and secure API endpoints 5. Content Validation: Validate and sanitize all data received from external sources before binding 6. Use HTTPS: Always use HTTPS for remote data connections 7. Rate Limiting: Implement rate limiting on API endpoints to prevent abuse

Security Risks:

• Indirect Prompt Injection: Untrusted third-party data can contain malicious content that manipulates AI agent behavior
• Data Exfiltration: Malicious data sources could attempt to extract sensitive information
• Code Injection: Untrusted data may contain scripts or harmful content

Recommended Approach:

✅ DO: Use controlled, authenticated backend APIs ✅ DO: Implement server-side data validation ✅ DO: Use configuration files for API endpoints ✅ DO: Whitelist allowed data sources

❌ DON'T: Accept user-provided URLs ❌ DON'T: Bind to public, untrusted endpoints ❌ DON'T: Skip data validation and sanitization ❌ DON'T: Use HTTP for sensitive data

Key Properties

Aggregation — Syncfusion Blazor Pivot Table

Aggregation determines how numeric values are summarized in Pivot Table cells. By default, values are summed. You can configure per-field aggregation types both programmatically and interactively via the Field List or Grouping Bar.

Note: Aggregation applies to relational data sources only. String, boolean, and date fields support only Count and DistinctCount.

Setting Aggregation Programmatically

Set the Type property on PivotViewValue using SummaryTypes:

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <!-- Default: Sum -->
            <PivotViewValue Name="Sold" Caption="Units Sold"
                            Type="SummaryTypes.Sum"></PivotViewValue>
            <!-- Average amount -->
            <PivotViewValue Name="Amount" Caption="Avg Amount"
                            Type="SummaryTypes.Avg"></PivotViewValue>
            <!-- % of grand total -->
            <PivotViewValue Name="Sold" Caption="% of Total"
                            Type="SummaryTypes.PercentageOfGrandTotal"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
}

---

DifferenceFrom and PercentageOfDifferenceFrom

These types compare each cell value to a specific member in a base field. Configure BaseField and BaseItem:

<PivotViewValues>
    <PivotViewValue Name="Amount" Caption="Diff from FY 2022"
                    Type="SummaryTypes.DifferenceFrom"
                    BaseField="Year"
                    BaseItem="FY 2022">
    </PivotViewValue>
    <PivotViewValue Name="Amount" Caption="% Diff from FY 2022"
                    Type="SummaryTypes.PercentageOfDifferenceFrom"
                    BaseField="Year"
                    BaseItem="FY 2022">
    </PivotViewValue>
</PivotViewValues>

Use case: Show year-over-year growth by comparing each year's revenue against the baseline year.

---

PercentageOfParentTotal

Shows each cell as a percentage of its parent total. Use BaseField to specify which parent field:

<PivotViewValues>
    <PivotViewValue Name="Sold" Caption="% of Country Total"
                    Type="SummaryTypes.PercentageOfParentTotal"
                    BaseField="Country">
    </PivotViewValue>
</PivotViewValues>

---

Changing Aggregation at Runtime via UI

When ShowGroupingBar="true" or ShowFieldList="true", users can change the aggregation type by clicking the value type icon (Σ) on a value field chip. A dropdown appears with all available SummaryTypes.

To allow this, no extra configuration is needed — it's enabled by default when the grouping bar or field list is visible.

To hide the aggregation type icon:

<PivotViewGroupingBarSettings ShowValueTypeIcon="false">
</PivotViewGroupingBarSettings>

Calculated Fields — Syncfusion Blazor Pivot Table

Calculated fields let users define custom value fields using mathematical formulas based on existing fields. They appear alongside regular value fields in the Pivot Table. Only applicable to relational data sources.

Enable Calculated Fields

Set AllowCalculatedField="true" on SfPivotView. This also surfaces the CALCULATED FIELD button in the Field List UI.

<SfPivotView TValue="ProductDetails" AllowCalculatedField="true" ShowFieldList="true">

---

Define a Calculated Field Programmatically

Use PivotViewCalculatedFieldSettings inside PivotViewDataSourceSettings. The calculated field must also be added to PivotViewValues with Type=SummaryTypes.CalculatedField to appear in the grid.

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails" ShowFieldList="true" AllowCalculatedField="true">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
            <PivotViewColumn Name="Quarter"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
            <!-- Calculated field: must be declared here AND in CalculatedFieldSettings -->
            <PivotViewValue Name="TotalRevenue" Caption="Total Revenue"
                            Type="SummaryTypes.CalculatedField">
            </PivotViewValue>
        </PivotViewValues>
        <PivotViewFormatSettings>
            <PivotViewFormatSetting Name="Amount" Format="C"></PivotViewFormatSetting>
            <PivotViewFormatSetting Name="TotalRevenue" Format="C"></PivotViewFormatSetting>
        </PivotViewFormatSettings>
        <PivotViewCalculatedFieldSettings>
            <PivotViewCalculatedFieldSetting Name="TotalRevenue"
                Formula="@formula">
            </PivotViewCalculatedFieldSetting>
        </PivotViewCalculatedFieldSettings>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    // Formula: Sum(Amount) + Sum(Sold) — field names wrapped in quotes
    public string formula = "\"Sum(Amount)\"" + "+" + "\"Sum(Sold)\"";
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
}

---

Open the Calculated Field Dialog via UI

When AllowCalculatedField="true" and ShowFieldList="true", a CALCULATED FIELD button appears at the bottom of the Field List dialog. Clicking it opens an interactive editor where users can:

• Name the new field
• Build formulas by clicking existing fields
• Preview the formula

---

Open Dialog Programmatically

Trigger the dialog from any external button using CreateCalculatedFieldDialogAsync:

@using Syncfusion.Blazor.PivotView
@using Syncfusion.Blazor.Buttons

<SfButton OnClick="OpenDialog">Add Calculated Field</SfButton>

<SfPivotView TValue="ProductDetails" @ref="pivot" AllowCalculatedField="true">
    <PivotViewDataSourceSettings DataSource="@data">
        ...
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    SfPivotView<ProductDetails> pivot;
    List<ProductDetails> data = ProductDetails.GetProductData().ToList();

    async Task OpenDialog() => await pivot.CreateCalculatedFieldDialogAsync();
}

---

Formula Syntax

Formulas use aggregation functions with field names wrapped in double quotes:

In C# string literals, inner quotes must be escaped or use @"..." with doubled quotes:

// Option 1: escape
string formula = "\"Sum(Amount)\" / \"Count(Sold)\"";

// Option 2: verbatim with doubled quotes
string formula = @"""Sum(Amount)"" / ""Count(Sold)""";

---

Gotchas

⚠️ Most Common Mistake — Will Silently Break Your Calculated Field:

>

Adding a PivotViewCalculatedFieldSetting is NOT enough on its own. You must also declare the field in PivotViewValues with Type="SummaryTypes.CalculatedField" explicitly set. Without Type=SummaryTypes.CalculatedField, the field will not render at all — no error is thrown.

>

```razor

<!-- ✅ CORRECT: Both declarations required -->

<PivotViewValues>

<PivotViewValue Name="TotalRevenue" Caption="Total Revenue"

Type="SummaryTypes.CalculatedField"> <!-- ← REQUIRED -->

</PivotViewValue>

</PivotViewValues>

<PivotViewCalculatedFieldSettings>

<PivotViewCalculatedFieldSetting Name="TotalRevenue" Formula="@formula">

</PivotViewCalculatedFieldSetting>

</PivotViewCalculatedFieldSettings>

>

<!-- ❌ WRONG: Missing Type — field won't appear in the grid -->

<PivotViewValue Name="TotalRevenue" Caption="Total Revenue">

</PivotViewValue>

```

• Calculated fields only work with relational data sources, not OLAP
• Field names in formulas are case-sensitive and must exactly match the property names in your data model
• Format settings for the calculated field must be declared separately in PivotViewFormatSettings

Connecting to Data Sources — Syncfusion Blazor Pivot Table

⚠️ CRITICAL SECURITY NOTICE

All database connections MUST be handled through secure server-side services. This documentation assumes proper security measures are in place:

✅ Required Security Controls:

• Secure connection strings (never exposed to client)
• Proper authentication and authorization
• SQL injection prevention (parameterized queries)
• Input validation and sanitization
• Rate limiting and monitoring
• Encrypted connections (SSL/TLS)
• Principle of least privilege for database access

❌ NEVER:

• Expose connection strings in client code
• Allow direct database access from browser
• Accept user-provided connection strings or queries
• Skip input validation and parameterization
• Use plaintext database connections

Table of Contents

• Overview
• Security Best Practices
• Microsoft SQL Server
• MySQL
• PostgreSQL
• MongoDB
• Oracle
• Snowflake
• Elasticsearch
• Web API Pattern (Recommended for Production)

---

Overview

For connecting databases to the Blazor Pivot Table, the recommended pattern is: 1. Create a Blazor Server or Web API service that queries the database 2. Return data as List<T> or JSON 3. Bind the result to PivotViewDataSourceSettings.DataSource

🔒 Security Requirement: Direct database access from Blazor WASM is not possible and should NEVER be attempted. Always use a server-side service or Web API with proper authentication.

---

Security Best Practices

Database Connection Security

1. Secure Connection Strings

✅ DO: Store in secure configuration

// appsettings.json (server-side only)
{
  "ConnectionStrings": {
    "SalesDB": "Server=localhost;Database=SalesDB;Integrated Security=True;"
  }
}

// Usage
@inject IConfiguration Configuration
string conStr = Configuration.GetConnectionString("SalesDB");

❌ DON'T: Hardcode connection strings

// NEVER DO THIS
string conStr = "Server=prod-db;User=admin;Password=secret123;";

2. SQL Injection Prevention

✅ DO: Use parameterized queries

string query = "SELECT * FROM Orders WHERE CustomerId = @customerId";
var command = new SqlCommand(query, connection);
command.Parameters.AddWithValue("@customerId", customerId);

❌ DON'T: Use string concatenation

// VULNERABLE TO SQL INJECTION
string query = $"SELECT * FROM Orders WHERE CustomerId = '{customerId}'";

3. Authentication & Authorization

[Authorize(Roles = "DataAnalyst")]
[HttpGet]
public IActionResult GetPivotData()
{
    // Verify user has permission to access this data
    if (!User.HasClaim("Permission", "ViewSalesData"))
        return Forbid();
    
    // Return data
}

4. Input Validation

private bool ValidateInput(string input)
{
    // Validate against whitelist
    if (string.IsNullOrWhiteSpace(input) || input.Length > 100)
        return false;
    
    // Check for suspicious patterns
    if (input.Contains("--") || input.Contains(";"))
        return false;
    
    return true;
}

5. Error Handling

try
{
    // Database operations
}
catch (Exception ex)
{
    // Log error internally
    _logger.LogError(ex, "Database error");
    
    // Return generic error to client (don't expose details)
    return StatusCode(500, "An error occurred processing your request");
}

string query  = "SELECT * FROM orders";

using var connection = new OracleConnection(conStr);
connection.Open();
using var adapter = new OracleDataAdapter(query, connection);
var table = new DataTable();
adapter.Fill(table);

---

Snowflake

Install: Snowflake.Data

using Snowflake.Data.Client;

string conStr = "account=myaccount;user=myuser;password=mypass;db=SALES;schema=PUBLIC;warehouse=COMPUTE_WH;";

using var connection = new SnowflakeDbConnection { ConnectionString = conStr };
connection.Open();
using var command = connection.CreateCommand();
command.CommandText = "SELECT * FROM ORDERS";
using var reader = command.ExecuteReader();

var dataSource = new List<OrderDetails>();
while (reader.Read())
{
    dataSource.Add(new OrderDetails
    {
        Product  = reader["PRODUCT"].ToString(),
        Amount   = Convert.ToDouble(reader["AMOUNT"]),
        // ... map other fields
    });
}

---

Elasticsearch

Install: NEST (Elasticsearch .NET client)

using Nest;

var settings = new ConnectionSettings(new Uri("http://localhost:9200"))
    .DefaultIndex("orders");
var client = new ElasticClient(settings);

var response = client.Search<OrderDetails>(s => s.MatchAll().Size(10000));
List<OrderDetails> dataSource = response.Documents.ToList();

---

Web API Pattern (Recommended for Production)

For Blazor WASM or large-scale apps, expose data via a Web API controller and use SfDataManager with WebApiAdaptor:

API Controller (`OrdersController.cs`):

[ApiController]
[Route("api/[controller]")]
public class OrdersController : ControllerBase
{
    private readonly IDbService _db;

    [HttpGet]
    public IActionResult Get() => Ok(_db.GetOrderData());
}

Blazor Component:

@using Syncfusion.Blazor.Data

<SfPivotView TValue="OrderDetails" Height="450">
    <PivotViewDataSourceSettings TValue="OrderDetails">
        <SfDataManager Url="/api/orders"
                       Adaptor="Syncfusion.Blazor.Adaptors.WebApiAdaptor">
        </SfDataManager>
        <PivotViewColumns>
            <PivotViewColumn Name="Product"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Amount"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
</SfPivotView>

Why prefer Web API? It decouples data access from UI, supports caching, authentication, and works with all Blazor hosting models including WASM.

Data Binding — Syncfusion Blazor Pivot Table

⚠️ SECURITY NOTICE

CRITICAL: This documentation contains examples for connecting to remote data sources. Always use trusted, authenticated data sources only. Never bind to untrusted URLs, user-provided endpoints, or public APIs without proper validation and security controls. See the Security Best Practices section below.

Security Best Practices

Critical Security Guidelines

When implementing data binding for pivot tables, follow these essential security practices:

1. Use Trusted Data Sources Only

✅ RECOMMENDED: Local in-memory data

// Safe: Local data list
public List<ProductDetails> data { get; set; }
protected override void OnInitialized()
{
    data = ProductDetails.GetProductData().ToList();
}

❌ AVOID: Untrusted remote endpoints

// UNSAFE: Never use arbitrary or user-provided URLs
Url = userProvidedUrl  // Security risk!

2. Implement Authentication for Remote Sources

If you must use remote data, always use authenticated endpoints:

// Use authenticated API with proper configuration
<SfDataManager Url="@Configuration["ApiEndpoint"]" 
               Adaptor="Adaptors.WebApiAdaptor"
               Headers="@headers">
</SfDataManager>

@code {
    private object[] headers = new object[] {
        new { Authorization = $"Bearer {AuthToken}" }
    };
}

3. Validate and Sanitize Data

Always validate data received from external sources:

protected override async Task OnInitializedAsync()
{
    var response = await Http.GetFromJsonAsync<List<ProductDetails>>(trustedEndpoint);
    
    // Validate data structure
    if (ValidateDataStructure(response))
    {
        data = SanitizeData(response);
    }
}

4. Use Configuration Settings

Store API endpoints in configuration, never hardcode:

// appsettings.json
{
  "ApiEndpoint": "https://your-trusted-api.com/data",
  "AllowedOrigins": ["https://your-domain.com"]
}

Security Risks to Avoid

---

Local JSON / IEnumerable Binding

Assign a List<T> (or any IEnumerable<T>) directly to the DataSource property inside PivotViewDataSourceSettings. This is the default and most common approach.

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
            <PivotViewColumn Name="Quarter"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Unit Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
        </PivotViewValues>
        <PivotViewFormatSettings>
            <PivotViewFormatSetting Name="Amount" Format="C"></PivotViewFormatSetting>
        </PivotViewFormatSettings>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized()
    {
        data = ProductDetails.GetProductData().ToList();
    }
}

---

SfDataManager with JsonAdaptor

Use SfDataManager with JsonAdaptor when you need to pass in-memory JSON (e.g., deserialized from an API response) without binding it as a typed list.

@using Syncfusion.Blazor.PivotView
@using Syncfusion.Blazor.Data

<SfPivotView TValue="ProductDetails" Width="1500" Height="300">
    <PivotViewDataSourceSettings TValue="ProductDetails" EnableSorting="true">
        <SfDataManager Json="@data" Adaptor="Syncfusion.Blazor.Adaptors.JsonAdaptor">
        </SfDataManager>
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
    <PivotViewGridSettings ColumnWidth="120"></PivotViewGridSettings>
</SfPivotView>

@code {
    ProductDetails[] data { get; set; }
    protected override void OnInitialized()
    {
        data = ProductDetails.GetProductData().ToArray();
    }
}

---

Remote Data (WebAPI / OData)

⚠️ SECURITY WARNING: Only use trusted, authenticated endpoints. Never bind to user-provided or untrusted URLs.

Point SfDataManager at a trusted and authenticated API endpoint and choose the appropriate adaptor:

• WebApiAdaptor — REST API returning JSON
• ODataV4Adaptor — OData v4 protocol
• UrlAdaptor — Custom endpoint with Syncfusion query format

@using Syncfusion.Blazor.PivotView
@using Syncfusion.Blazor.Data
@inject IConfiguration Configuration

<SfPivotView TValue="OrderData" Height="450">
    <PivotViewDataSourceSettings TValue="OrderData" ExpandAll="false">
        <!-- ⚠️ SECURITY: Only use controlled, trusted endpoints -->
        <SfDataManager Url="@Configuration["ApiEndpoint"]"
                       Adaptor="Syncfusion.Blazor.Adaptors.WebApiAdaptor" CrossDomain="true">
        </SfDataManager>
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="ProductName"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Quantity" Caption="Qty Sold"></PivotViewValue>
            <PivotViewValue Name="UnitPrice" Caption="Total Revenue"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
</SfPivotView>

Note: The API must support $filter, $top, and $skip query parameters for the adaptor to function correctly. For custom APIs, return data in { result: [], count: N } format with UrlAdaptor.

---

OLAP Cube Data Source

Connect to OLAP cubes (SQL Server Analysis Services, SSAS) using PivotViewOlapDataSourceSettings:

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="string">
    <PivotViewDataSourceSettings TValue="string"
        ProviderType="ProviderType.SSAS"
        Catalog="Adventure Works DW 2008 SE"
        Cube="Adventure Works"
        Url="https://demos.syncfusion.com/olap/msmdpump.dll"
        LocaleIdentifier="1033" EnableSorting="true">
        <PivotViewColumns>
            <PivotViewColumn Name="[Product].[Product Categories]" Caption="Product Categories">
            </PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="[Customer].[Customer Geography]" Caption="Customer Geography">
            </PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="[Measures].[Customer Count]" Caption="Customer Count">
            </PivotViewValue>
            <PivotViewValue Name="[Measures].[Internet Sales Amount]" Caption="Internet Sales">
            </PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
</SfPivotView>

Tip: OLAP-specific features like MDX queries and member leveling require the toolbar's MDX option to be enabled via ToolbarItems.MDX.

---

Dynamic Data Objects

The Pivot Table supports ExpandoObject and other dynamic types when the schema is not known at compile time:

<SfPivotView TValue="ExpandoObject">
    <PivotViewDataSourceSettings DataSource="@data">
        ...
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    List<ExpandoObject> data = new();
    protected override void OnInitialized()
    {
        dynamic row1 = new ExpandoObject();
        row1.Country = "France"; row1.Year = "FY 2023"; row1.Amount = 5000;
        data.Add(row1);
        // add more rows...
    }
}

---

ExpandAll on Load

By default, only top-level members are shown. Set ExpandAll="true" to expand all hierarchy levels on initial render:

<PivotViewDataSourceSettings DataSource="@data" ExpandAll="true">

Performance note: ExpandAll on large datasets increases initial render time. Prefer expanding specific members programmatically for better UX.

---

Refresh Data Programmatically

Using RefreshAsync Method

The RefreshAsync() method provides dynamic and asynchronous refreshing of the Pivot Table. Use it to update the component after programmatic changes to the data source or report configuration.

Method Signature

Task RefreshAsync(bool updateDataSource = false)

Parameters:

• updateDataSource (bool):
• true: Full refresh including data re-processing (complete engine rebuild)
• false: Layout-only refresh (default, faster)

When to Use RefreshAsync

• After programmatically adding/removing fields from axes
• After changing aggregation types or calculated fields
• After modifying filter or sort settings
• When data source properties change
• After updating formatting rules

Full Refresh Example

Use true parameter when the underlying data has changed or when adding/removing fields:

<button @onclick="AddProductField">Add Product to Rows</button>

<SfPivotView @ref="pivotView" TValue="ProductDetails">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sales Amount"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    SfPivotView<ProductDetails> pivotView;
    List<ProductDetails> data = ProductDetails.GetProductData().ToList();

    private async Task AddProductField()
    {
        // Add new field programmatically
        // Note: In practice, you'd manipulate the report configuration
        
        // Full refresh to rebuild the engine with new field
        await pivotView.RefreshAsync(true);
    }
}

Layout Refresh Example

Use false (or omit parameter) for UI-only changes that don't require data reprocessing:

<button @onclick="ChangeFormat">Update Formatting</button>

<SfPivotView @ref="pivotView" TValue="ProductDetails">
    <PivotViewDataSourceSettings DataSource="@data">
        <!-- configuration -->
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    SfPivotView<ProductDetails> pivotView;

    private async Task ChangeFormat()
    {
        // Modify formatting or other display properties
        
        // Layout refresh only (faster)
        await pivotView.RefreshAsync(false);
        // or simply: await pivotView.RefreshAsync();
    }
}

Updating Data and Refreshing

When data changes, refresh to reflect updates:

<button @onclick="LoadNewData">Load Updated Data</button>

<SfPivotView @ref="pivotView" TValue="ProductDetails">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    SfPivotView<ProductDetails> pivotView;
    List<ProductDetails> data;

    protected override void OnInitialized()
    {
        data = ProductDetails.GetProductData().ToList();
    }

    private async Task LoadNewData()
    {
        // Update data source
        data = await FetchLatestDataFromDatabase();
        
        // Full refresh to process new data
        await pivotView.RefreshAsync(true);
    }
}

Performance Considerations

Best Practice: Use layout refresh (false) when possible for better performance.

Alternative: Data Reassignment Pattern

For simple data updates, you can reassign the data collection to trigger a re-render:

<SfPivotView TValue="ProductDetails" @ref="pivot">
    <PivotViewDataSourceSettings DataSource="@data"> ... </PivotViewDataSourceSettings>
</SfPivotView>
<button @onclick="Refresh">Refresh</button>

@code {
    SfPivotView<ProductDetails> pivot;
    List<ProductDetails> data = ProductDetails.GetProductData().ToList();

    void Refresh()
    {
        // Replace list reference so Blazor detects the change
        data = FetchNewData().ToList();
        StateHasChanged();
    }
}

Note: Data reassignment works for simple scenarios. Use RefreshAsync() for complex updates or when you need fine control over the refresh behavior.

Drill Down — Syncfusion Blazor Pivot Table

Drill down enables expanding and collapsing hierarchical members (e.g., Year → Quarter, Country → City) in row and column headers. Users can interactively explore data at different levels, and you can programmatically control expansion.

Drill Down and Drill Up

When a field has hierarchical members, expand/collapse icons automatically appear on row and column headers. Click the + icon to drill down (expand children) and the - icon to drill up (collapse).

This feature is built-in and requires no additional configuration when multiple fields are placed on the same axis.

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
            <PivotViewColumn Name="Quarter"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
}

Expand All on Load

By default, only the top-level members are shown. Set ExpandAll="true" to show all levels expanded from the start:

<PivotViewDataSourceSettings DataSource="@data" ExpandAll="true">

Applies to: Relational data sources only.

Expand Specific Members on Load

Use PivotViewDrilledMember inside PivotViewDataSourceSettings to expand only specific members programmatically:

⚠️ `Name` Must Be the Field Name, Not a Member Value:

>

PivotViewDrilledMember.Name refers to the field name (the property/column name), not a member caption or a modified value like "Year_FY2023". The members to expand go in Items.

<PivotViewDataSourceSettings DataSource="@data">
    ...
    <PivotViewDrilledMembers>
        <!-- Pre-expand "FY 2023" under Year column -->
        <PivotViewDrilledMember Name="Year" Items="@(new string[] { "FY 2023" })">
        </PivotViewDrilledMember>
        <!-- Pre-expand "France" under Country row -->
        <PivotViewDrilledMember Name="Country" Items="@(new string[] { "France" })">
        </PivotViewDrilledMember>
    </PivotViewDrilledMembers>
</PivotViewDataSourceSettings>

Drill Position (Independent Drill)

Drilling down on a member in one position does not affect the same member name appearing elsewhere. For example, if both FY 2022 and FY 2023 have "Q1" as a child:

• Expanding Q1 under FY 2022 only expands that specific Q1
• Q1 under FY 2023 remains collapsed

This behavior is automatic and cannot be disabled — it ensures precise data focus.

Responding to Drill Operations with Events

Use the OnActionBegin event to detect drill-down and drill-up actions before they execute, and optionally block them:

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails" ShowGroupingBar="true">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
            <PivotViewColumn Name="Quarter"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
    <PivotViewEvents TValue="ProductDetails" OnActionBegin="ActionBegin">
    </PivotViewEvents>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();

    public void ActionBegin(PivotActionBeginEventArgs args)
    {
        if (args.ActionName == "Drill down")
        {
            // Handle drill down action
            Console.WriteLine("User is drilling down");
            // Optionally block the action
            // args.Cancel = true;
        }
        else if (args.ActionName == "Drill up")
        {
            // Handle drill up action
            Console.WriteLine("User is drilling up");
        }
    }
}

The ActionName parameter indicates the drill action:

• "Drill down" - User expanded a member
• "Drill up" - User collapsed a member

Drill Through — Syncfusion Blazor Pivot Table

Drill-through displays the raw underlying records behind an aggregated value cell in a popup data grid, allowing users to inspect detailed transactions that contribute to a summary figure.

Enable Drill Through

Double-clicking the value cell opens the drill-through dialog listing all rows that contribute to that aggregated value.

Enable drill-through:

<SfPivotView TValue="ProductDetails" AllowDrillThrough="true">
    ...
</SfPivotView>

Configure Drill Through Grid

Configure the detail grid columns (optional):

<SfPivotView TValue="ProductDetails" AllowDrillThrough="true">
    <PivotViewDataSourceSettings DataSource="@data">
        ...
    </PivotViewDataSourceSettings>
    <PivotViewDrillThroughSettings
        EnableColumnVirtualization="false">
    </PivotViewDrillThroughSettings>
</SfPivotView>

Use Cases

Drill-through is ideal for financial reports where analysts need to see the transactions behind a summary figure. It surfaces data without navigating away from the pivot report.

Editing — Syncfusion Blazor Pivot Table

Cell editing lets users add, update, or delete raw data directly through the Pivot Table UI. Double-clicking a value cell opens a detail data grid in a popup showing the underlying records. CRUD operations performed there automatically recalculate pivot aggregates.

Applies to: Relational data sources only.

Enable Editing

⚠️ Correct Tag Name — Frequently Confused:

>

The editing configuration tag is `PivotViewCellEditSettings` — NOT PivotViewEditSettings. The incorrect tag does not exist and will silently fail or cause a compile error.

>

```razor

<!-- ✅ CORRECT -->

<PivotViewCellEditSettings AllowEditing="true" Mode="EditMode.Normal">

</PivotViewCellEditSettings>

>

<!-- ❌ WRONG — this tag does not exist -->

<PivotViewEditSettings AllowEditing="true">

</PivotViewEditSettings>

```

Add PivotViewCellEditSettings inside SfPivotView:

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
    <PivotViewCellEditSettings
        AllowAdding="true"
        AllowEditing="true"

        AllowEditOnDblClick="true"
        Mode="EditMode.Normal">
    </PivotViewCellEditSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
}

`PivotViewCellEditSettings` properties:

---

Edit Modes

---

Normal Mode

One row edits at a time in place:

<PivotViewCellEditSettings AllowEditing="true" AllowAdding="true"
    AllowDeleting="true" Mode="EditMode.Normal">
</PivotViewCellEditSettings>

---

Dialog Mode

Opens a dialog per row for editing:

<PivotViewCellEditSettings AllowEditing="true" AllowAdding="true"
    AllowDeleting="true" Mode="EditMode.Dialog">
</PivotViewCellEditSettings>

---

Batch Mode

Queue multiple edits and commit all at once with a single Update click:

<PivotViewCellEditSettings AllowEditing="true" AllowAdding="true"
    AllowDeleting="true" Mode="EditMode.Batch">
</PivotViewCellEditSettings>

Use case: When users need to modify many records at once (e.g., bulk price adjustments) without triggering a pivot recalculation after each individual edit.

---

Command Columns Mode

Adds dedicated Edit and Delete buttons in each row of the detail grid:

<PivotViewCellEditSettings AllowEditing="true" AllowAdding="true"
    AllowDeleting="true" AllowCommandColumns="true"
    Mode="EditMode.CommandColumn">
</PivotViewCellEditSettings>

---

Inline Editing

Enable direct cell editing without a popup row transition:

<PivotViewCellEditSettings AllowEditing="true" AllowInlineEditing="true">
</PivotViewCellEditSettings>

---

Confirmation Dialogs

Show confirmation prompts to prevent accidental changes:

<PivotViewCellEditSettings

Excel Export — Syncfusion Blazor Pivot Table

Excel export allows you to export the pivot table data to Microsoft Excel format with formatting, formulas, and styling preserved.

Excel Export

Enable with AllowExcelExport="true" and call ExportToExcelAsync():

@using Syncfusion.Blazor.PivotView
@using Syncfusion.Blazor.Buttons

<SfButton OnClick="OnExcelExport" Content="Export to Excel"></SfButton>

<SfPivotView TValue="ProductDetails" @ref="pivot" AllowExcelExport="true">
    <PivotViewDataSourceSettings DataSource="@data" EnableSorting="true">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
            <PivotViewColumn Name="Quarter"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
        </PivotViewValues>
        <PivotViewFormatSettings>
            <PivotViewFormatSetting Name="Amount" Format="C0" UseGrouping="true">
            </PivotViewFormatSetting>
        </PivotViewFormatSettings>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    SfPivotView<ProductDetails> pivot;
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();

    // false = direct download; true = returns MemoryStream
    public void OnExcelExport() => pivot.ExportToExcelAsync(false);
}

---

CSV Export

Export as a comma-separated CSV file — useful for further processing in Excel or data pipelines:

<SfButton OnClick="OnCsvExport" Content="Export to CSV"></SfButton>

@code {
    // AllowExcelExport must be true for CSV export as well
    public void OnCsvExport() => pivot.ExportToCsvAsync(false);
}

---

Export as Memory Stream

Pass true to get a MemoryStream instead of downloading — useful for server-side file generation or email attachments:

@code {
    public async Task ExportToStream()
    {
        // Returns MemoryStream — save to disk, email, or upload to storage
        MemoryStream stream = await pivot.ExportToExcelAsync(true) as MemoryStream;
        // e.g., save to file:
        await File.WriteAllBytesAsync("output.xlsx", stream.ToArray());
    }
}

---

Custom File Name and Settings

Excel export with custom file name

To set a custom file name, create an ExcelExportProperties object and pass it to the export method:

// ✅ CORRECT — pass ExcelExportProperties with FileName
var exportProperties = new ExcelExportProperties { FileName = "MyReport.xlsx" };
await pivot.ExportToExcelAsync(exportProperties);

Full example:

@code {
    public async Task OnExcelExport()
    {
        var exportProperties = new ExcelExportProperties
        {
            FileName = "SalesReport_Q4_2024.xlsx"
        };
        await pivot.ExportToExcelAsync(exportProperties);
    }
}

Field List — Syncfusion Blazor Pivot Table

The Field List is a UI panel (similar to Excel's PivotTable Fields pane) that lets users drag fields between row, column, value, and filter axes at runtime, apply sorting and filtering, and configure the Pivot Table layout interactively.

Table of Contents

• In-Built Field List (Popup)
• Stand-Alone Field List (Fixed)
• Defer Layout Update
• Customizing the Field List
• Field List with Grouping Bar

---

In-Built Field List (Popup)

Enable the popup field list by setting ShowFieldList="true" on SfPivotView. A small icon appears in the top-left (or top-right when the grouping bar is enabled) of the Pivot Table — clicking it opens the field list dialog.

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails" ShowFieldList="true">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
            <PivotViewColumn Name="Quarter"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
        </PivotViewValues>
        <PivotViewFormatSettings>
            <PivotViewFormatSetting Name="Amount" Format="C"></PivotViewFormatSetting>
        </PivotViewFormatSettings>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
}

---

Stand-Alone Field List (Fixed)

Render the field list as a separate SfPivotFieldList component alongside the Pivot Table. This gives a permanent panel layout similar to Excel's default view.

@using Syncfusion.Blazor.PivotView

<div style="display: flex; gap: 16px;">
    <SfPivotView TValue="ProductDetails" @ref="pivotRef" Height="530">
        <PivotViewDataSourceSettings DataSource="@data" EnableSorting="true">
            <PivotViewColumns>
                <PivotViewColumn Name="Year"></PivotViewColumn>
            </PivotViewColumns>
            <PivotViewRows>
                <PivotViewRow Name="Country"></PivotViewRow>
                <PivotViewRow Name="Products"></PivotViewRow>
            </PivotViewRows>
            <PivotViewValues>
                <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
            </PivotViewValues>
        </PivotViewDataSourceSettings>
        <PivotViewEvents TValue="ProductDetails"
                         EnginePopulated="@UpdateFieldList">
        </PivotViewEvents>
    </SfPivotView>

    <SfPivotFieldList TValue="ProductDetails" @ref="fieldListRef"
                      RenderMode="Mode.Fixed" AllowCalculatedField="true">
        <PivotFieldListDataSourceSettings DataSource="@data" EnableSorting="true">
            <PivotFieldListColumns>
                <PivotFieldListColumn Name="Year"></PivotFieldListColumn>
            </PivotFieldListColumns>
            <PivotFieldListRows>
                <PivotFieldListRow Name="Country"></PivotFieldListRow>
            </PivotFieldListRows>
            <PivotFieldListValues>
                <PivotFieldListValue Name="Amount" Caption="Sold Amount"></PivotFieldListValue>
            </PivotFieldListValues>
        </PivotFieldListDataSourceSettings>
        <PivotFieldListEvents TValue="ProductDetails"
                              EnginePopulated="@UpdatePivotView">
        </PivotFieldListEvents>
    </SfPivotFieldList>
</div>

@code {
    SfPivotView<ProductDetails> pivotRef;
    SfPivotFieldList<ProductDetails> fieldListRef;
    List<ProductDetails> data = ProductDetails.GetProductData().ToList();

    async Task UpdateFieldList(EnginePopulatedEventArgs args)
    {
        await fieldListRef.UpdateAsync(pivotRef);
    }

    async Task UpdatePivotView(EnginePopulatedEventArgs args)
    {
        await fieldListRef.UpdateViewAsync(pivotRef);
    }
}

Why use stand-alone? It keeps the pivot grid area uncluttered and gives users a persistent panel to configure the report — ideal for analytics dashboards.

---

Defer Layout Update

When users make multiple field changes (drag fields, change aggregations) the Pivot Table re-renders after every action, which can be slow. Enable AllowDeferLayoutUpdate to batch all changes and apply them when the user explicitly clicks the Update button.

<SfPivotView TValue="ProductDetails" AllowDeferLayoutUpdate="true" ShowFieldList="true">
    ...
</SfPivotView>

Or on the stand-alone field list:

<SfPivotFieldList TValue="ProductDetails" AllowDeferLayoutUpdate="true" RenderMode="Mode.Fixed">

When to use: Essential for large datasets where each re-render is expensive. Reduces server calls in Blazor Server apps.

---

Customizing the Field List

Hide specific fields from the field list

<PivotViewDataSourceSettings DataSource="@data">
    <!-- Field captions rename display name in field list -->
    <PivotViewColumn Name="Year" Caption="Fiscal Year"></PivotViewColumn>
</PivotViewDataSourceSettings>

Open field list dialog programmatically

<SfPivotView TValue="ProductDetails" @ref="pivot" ShowFieldList="false">
    ...
</SfPivotView>
<button @onclick="OpenFieldList">Open Field List</button>

@code {
    SfPivotView<ProductDetails> pivot;
    void OpenFieldList() => pivot.ShowFieldListAsync();
}

---

Field List with Grouping Bar

Both can be enabled simultaneously. The field list icon moves to the top-right corner when the grouping bar is visible:

<SfPivotView TValue="ProductDetails"
             ShowFieldList="true"
             ShowGroupingBar="true">
    ...
</SfPivotView>

Filtering — Syncfusion Blazor Pivot Table

Filtering lets users focus on specific members of their data by including or excluding items from the Pivot Table display. Three filter types are supported: Member, Label, and Value filtering.

Table of Contents

• Member Filtering
• Label Filtering
• Value Filtering
• Date Filtering
• Disable Filtering

---

Member Filtering

Member filtering shows or hides specific members of a field. Enabled by default via AllowMemberFilter in PivotViewDataSourceSettings.

Via UI

Click the filter icon on a field in the Field List or Grouping Bar. A dialog shows all members with checkboxes to include/exclude.

Programmatically

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails" ShowGroupingBar="true">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
            <PivotViewColumn Name="Quarter"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
        </PivotViewValues>
        <PivotViewFormatSettings>
            <PivotViewFormatSetting Name="Amount" Format="C0" UseGrouping="true">
            </PivotViewFormatSetting>
        </PivotViewFormatSettings>
        <PivotViewFilterSettings>
            <!-- Exclude FY 2017 from Year field -->
            <PivotViewFilterSetting Name="Year"
                Type="FilterType.Exclude"
                Items="@(new string[] { "FY 2017" })">
            </PivotViewFilterSetting>
            <!-- Include only France and Germany -->
            <PivotViewFilterSetting Name="Country"
                Type="FilterType.Include"
                Items="@(new string[] { "France", "Germany" })">
            </PivotViewFilterSetting>
        </PivotViewFilterSettings>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
}

Key properties on `PivotViewFilterSetting`:

• Name — the field name to filter
• Type — FilterType.Include or FilterType.Exclude
• Items — array of member values to include/exclude

---

Label Filtering

Label filtering applies conditions to row/column header text. For example, show only countries whose name begins with "F".

<PivotViewFilterSettings>
    <PivotViewFilterSetting Name="Country"
        Type="FilterType.Label"
        Condition="Operators.BeginWith"
        Value1="F">
    </PivotViewFilterSetting>
</PivotViewFilterSettings>

Available `Operators` for label filtering:

---

Value Filtering

Value filtering shows or hides members based on aggregated value conditions. For example, show only countries where total Amount > 100,000.

<PivotViewFilterSettings>
    <PivotViewFilterSetting Name="Country"
        Type="FilterType.Value"
        Measure="Amount"
        Condition="Operators.GreaterThan"
        Value1="100000">
    </PivotViewFilterSetting>
</PivotViewFilterSettings>

• Measure — the value field to evaluate (matches a PivotViewValue Name)
• Condition — comparison operator (Equals, GreaterThan, LessThan, Between, etc.)
• Value1 (and Value2 for Between) — threshold values

---

Date Filtering

For date fields, use FilterType.Date combined with date-specific operators:

<PivotViewFilterSettings>
    <PivotViewFilterSetting Name="OrderDate"
        Type="FilterType.Date"
        Condition="Operators.Between"
        Value1="2023-01-01"
        Value2="2023-12-31">
    </PivotViewFilterSetting>
</PivotViewFilterSettings>

---

Disable Filtering

Disable member filtering globally

<PivotViewDataSourceSettings DataSource="@data" AllowMemberFilter="false">

Disable label filtering globally

<PivotViewDataSourceSettings DataSource="@data" AllowLabelFilter="false">

Disable value filtering globally

<PivotViewDataSourceSettings DataSource="@data" AllowValueFilter="false">

When all filtering options are disabled, the filter icon will not appear in the Field List or Grouping Bar.

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
}

Key PivotViewFormatSetting properties

Custom format example

<!-- Show as "1,234.56 USD" -->
<PivotViewFormatSetting Name="Amount" Format="#,##0.00" Currency="USD">
</PivotViewFormatSetting>

---

Number Formatting via Toolbar at Runtime

Enable number formatting through the toolbar to let users change formats interactively:

<SfPivotView TValue="ProductDetails" ShowToolbar="true"
             Toolbar="@toolbar" AllowNumberFormatting="true">

@code {
    public List<ToolbarItems> toolbar = new List<ToolbarItems>
    {
        ToolbarItems.NumberFormatting
    };
}

---

Conditional Formatting

Apply CSS-style formatting (background color, font color, font size, font family) to value cells that meet specified conditions. This helps highlight key data points visually.

Programmatic configuration

Use PivotViewConditionalFormatSettings:

<SfPivotView TValue="ProductDetails" AllowConditionalFormatting="true">
    <PivotViewDataSourceSettings DataSource="@data">
        ...
    </PivotViewDataSourceSettings>
    <PivotViewConditionalFormatSettings>
        <!-- Highlight Amount cells > 100000 in green -->
        <PivotViewConditionalFormatSetting
            Measure="Amount"
            Conditions="Condition.GreaterThan"
            Value1="100000"
            Style="@highStyle">
        </PivotViewConditionalFormatSetting>
        <!-- Highlight Amount cells < 10000 in red -->
        <PivotViewConditionalFormatSetting
            Measure="Amount"
            Conditions="Condition.LessThan"
            Value1="10000"
            Style="@lowStyle">
        </PivotViewConditionalFormatSetting>
    </PivotViewConditionalFormatSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();

    PivotViewStyle highStyle = new PivotViewStyle
    {
        BackgroundColor = "#9ef59e",    // light green
        Color = "#004d00",              // dark green text
        FontSize = "14px",
        FontFamily = "Segoe UI"
    };

    PivotViewStyle lowStyle = new PivotViewStyle
    {
        BackgroundColor = "#f5a59e",    // light red
        Color = "#4d0000",              // dark red text
        FontSize = "14px",
        FontFamily = "Segoe UI"
    };
}

MAUI Blazor Setup

For MAUI Blazor hybrid apps:

1. Install Syncfusion.Blazor.PivotTable in the MAUI project 2. Register in MauiProgram.cs:

   builder.Services.AddSyncfusionBlazor();

3. Add CSS in wwwroot/index.html:

   <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />

4. Use SfPivotView in any .razor component as normal

---

Minimal Working Example

The smallest possible Pivot Table with data:

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="SalesData" Height="300">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Region"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Revenue"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    record SalesData(string Region, string Year, double Revenue);

    List<SalesData> data = new()
    {
        new("North", "FY 2023", 10000),
        new("North", "FY 2024", 12000),
        new("South", "FY 2023", 8000),
        new("South", "FY 2024", 9500),
    };
}

Grouping Bar — Syncfusion Blazor Pivot Table

The Grouping Bar is a drag-and-drop UI element rendered above the Pivot Table that displays the currently applied row, column, value, and filter fields. Users can rearrange, remove, filter, and sort fields interactively at runtime without needing to write code.

Enable Grouping Bar

Set ShowGroupingBar="true" on SfPivotView:

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails" ShowGroupingBar="true">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
            <PivotViewColumn Name="Quarter"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
        </PivotViewValues>
        <PivotViewFormatSettings>
            <PivotViewFormatSetting Name="Amount" Format="C"></PivotViewFormatSetting>
        </PivotViewFormatSettings>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
}

---

What Users Can Do in the Grouping Bar

---

Customizing Grouping Bar Behavior

Use PivotViewGroupingBarSettings inside SfPivotView to control which UI features are available:

<SfPivotView TValue="ProductDetails" ShowGroupingBar="true">
    <PivotViewDataSourceSettings DataSource="@data">
        ...
    </PivotViewDataSourceSettings>
    <PivotViewGroupingBarSettings
        ShowFilterIcon="true"
        ShowSortIcon="true"
        ShowRemoveIcon="true"
        ShowValueTypeIcon="true"
        AllowDragAndDrop="true">
    </PivotViewGroupingBarSettings>
</SfPivotView>

---

Show/Hide Specific Buttons

Disable all sorting icons in the grouping bar

<PivotViewGroupingBarSettings ShowSortIcon="false">
</PivotViewGroupingBarSettings>

Read-only grouping bar (no drag, no remove)

<PivotViewGroupingBarSettings
    AllowDragAndDrop="false"
    ShowRemoveIcon="false">
</PivotViewGroupingBarSettings>

---

Grouping Bar with Field List

The grouping bar and field list work together seamlessly. When both are enabled, the Field List icon moves to the top-right corner of the grouping bar area:

<SfPivotView TValue="ProductDetails"
             ShowGroupingBar="true"
             ShowFieldList="true">
    ...
</SfPivotView>

Pattern: Enable the grouping bar for users who primarily rearrange existing fields. Add the field list for users who need to add new fields from the data source. Both together give the full Excel-like pivot experience.

Grouping — Syncfusion Blazor Pivot Table

Grouping automatically organizes date, number, and string fields into meaningful categories (e.g., dates into Year/Quarter/Month, numbers into ranges). Grouped fields act as independent fields and can be moved between axes. Applies to relational data sources only.

• Enable Grouping
• Number Grouping
• Date Grouping
• Custom Grouping
• Programmatic Grouping Configuration

---

Enable Grouping

Set AllowGrouping="true" on SfPivotView. Users can then right-click any row/column header in the Pivot Table and select Group or Ungroup.

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails" ShowGroupingBar="true" AllowGrouping="true">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Product_ID" Caption="Product ID"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Date" Caption="Date"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
        </PivotViewValues>
        <PivotViewFormatSettings>
            <PivotViewFormatSetting Name="Date" Type="FormatType.DateTime"
                Format="dd/MM/yyyy-hh:mm">
            </PivotViewFormatSetting>
            <PivotViewFormatSetting Name="Amount" Format="C" UseGrouping="true">
            </PivotViewFormatSetting>
        </PivotViewFormatSettings>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
}

Only one type of grouping can be applied to a single field at a time (similar to Excel behavior).

---

Number Grouping

Groups numeric field members into ranges (e.g., Product IDs 1–5, 6–10).

Via UI: Right-click a numeric header → select Group → set start, end, and interval values.

Programmatically:

<PivotViewGroupSettings>
    <PivotViewGroupSetting Name="Product_ID" GroupInterval="5"
        StartingAt="1" EndingAt="200"
        Type="GroupType.Number">
    </PivotViewGroupSetting>
</PivotViewGroupSettings>

---

Date Grouping

Groups a DateTime field into hierarchical levels such as Year, Quarter, Month, Day, Hours, Minutes, Seconds.

Via UI: Right-click a date/time header → Group → select desired intervals.

Programmatically:

<PivotViewGroupSettings>
    <PivotViewGroupSetting Name="Date"
        Type="GroupType.Date"
        GroupByDate="@dateGroupSettings">
    </PivotViewGroupSetting>
</PivotViewGroupSettings>

@code {
    // Group by Year and Month
    public DateGroup dateGroupSettings = new DateGroup
    {
        Years = true,
        Months = true,
        Quarters = false,
        Days = false
    };
}

Available date group levels: Years, Quarters, Months, Days, Hours, Minutes, Seconds

Tip: Date grouping is the most common use case — group a date-of-order field by Year and Quarter to create time-series pivot reports without modifying the underlying data.

---

Custom Grouping

Groups selected members of a field into a custom named category. For example, group "Mountain Bikes" and "Road Bikes" into "Bikes".

Via UI: Select specific row/column members using Ctrl+click → right-click → Group → enter a group name.

Programmatically:

<PivotViewGroupSettings>
    <PivotViewGroupSetting Name="Products"
        Type="GroupType.Custom"
        CustomGroups="@customGroups">
    </PivotViewGroupSetting>
</PivotViewGroupSettings>

@code {
    List<CustomGroups> customGroups = new List<CustomGroups>
    {
        new CustomGroups
        {
            GroupName = "Bikes",
            Items = new string[] { "Mountain Bikes", "Road Bikes" }
        }
    };
}

---

Programmatic Grouping Configuration

Full example combining multiple settings:

<SfPivotView TValue="ProductDetails" AllowGrouping="true">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Date"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Product_ID"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Amount"></PivotViewValue>
        </PivotViewValues>
        <PivotViewFormatSettings>
            <PivotViewFormatSetting Name="Date" Type="FormatType.DateTime"
                Format="dd/MM/yyyy">
            </PivotViewFormatSetting>
        </PivotViewFormatSettings>
        <PivotViewGroupSettings>
            <!-- Group date by year and quarter -->
            <PivotViewGroupSetting Name="Date" Type="GroupType.Date"
                GroupByDate="@dateGroup">
            </PivotViewGroupSetting>
            <!-- Group Product IDs into ranges of 10 -->
            <PivotViewGroupSetting Name="Product_ID" GroupInterval="10"
                StartingAt="1" EndingAt="100" Type="GroupType.Number">
            </PivotViewGroupSetting>
        </PivotViewGroupSettings>
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
    DateGroup dateGroup = new DateGroup { Years = true, Quarters = true };
}

Layout & Display — Syncfusion Blazor Pivot Table

Table of Contents

• Width and Height
• Classic (Tabular) Layout
• Row & Column Customization
• Show or Hide Totals
• Hyperlinks in Cells
• Tooltip

---

Width and Height

Set dimensions using pixel values, percentages, or auto:

<!-- Fixed pixel size -->
<SfPivotView TValue="ProductDetails" Width="800" Height="400">

<!-- Responsive: fill container width -->
<SfPivotView TValue="ProductDetails" Width="100%" Height="500px">

<!-- Auto height: expands with content, parent scrolls -->
<SfPivotView TValue="ProductDetails" Width="100%" Height="auto">

Minimum width is 400px — values below this are ignored.

---

Classic (Tabular) Layout

The default layout is compact (hierarchical, indented). The classic/tabular layout places each row field in its own separate column, resembling a flat table — useful for exporting or when users prefer Excel-style pivot views.

Limitation: Classic layout works only with relational data sources and the client-side engine.

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails" Height="450" Width="100%">
    <PivotViewDataSourceSettings DataSource="@data">
        <PivotViewColumns>
            <PivotViewColumn Name="Year"></PivotViewColumn>
            <PivotViewColumn Name="Quarter"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="Country"></PivotViewRow>
            <PivotViewRow Name="Products"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
            <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
    <!-- Enable classic/tabular layout -->
    <PivotViewGridSettings Layout="PivotLayout.Tabular"></PivotViewGridSettings>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();
}

PivotLayout options:

• PivotLayout.Compact — default hierarchical view
• PivotLayout.Tabular — classic/tabular (each row field in its own column)

---

Row & Column Customization

Column width

<PivotViewGridSettings ColumnWidth="120"></PivotViewGridSettings>

Freeze rows and columns (sticky headers)

<PivotViewGridSettings FrozenRows="2" FrozenColumns="1"></PivotViewGridSettings>

Auto-fit columns

<PivotViewGridSettings AllowAutoResizing="true"></PivotViewGridSettings>

Row height

<PivotViewGridSettings RowHeight="36"></PivotViewGridSettings>

---

Show or Hide Totals

Control grand totals and sub-totals in PivotViewDataSourceSettings:

<!-- Hide all grand totals -->
<PivotViewDataSourceSettings DataSource="@data" ShowGrandTotals="false">

<!-- Hide only row grand totals -->
<PivotViewDataSourceSettings DataSource="@data" ShowRowGrandTotals="false">

<!-- Hide only column grand totals -->
<PivotViewDataSourceSettings DataSource="@data" ShowColumnGrandTotals="false">

<!-- Hide all sub-totals -->
<PivotViewDataSourceSettings DataSource="@data" ShowSubTotals="false">

<!-- Hide row sub-totals only -->
<PivotViewDataSourceSettings DataSource="@data" ShowRowSubTotals="false">

All totals are shown by default (true). Hiding them reduces visual clutter in reports with many nested levels.

---

Hyperlinks in Cells

Render cells as clickable hyperlinks and handle them via the HyperlinkCellClick event:

<SfPivotView TValue="ProductDetails">
    <PivotViewDataSourceSettings DataSource="@data">
        ...
    </PivotViewDataSourceSettings>
    <!-- Enable hyperlinks on value cells only -->
    <PivotViewHyperlinkSettings ShowValueCellHyperlink="true"
                                CssClass="e-custom-hyperlink">
    </PivotViewHyperlinkSettings>
    <PivotViewEvents TValue="ProductDetails"
                     HyperlinkCellClick="OnHyperlinkClick">
    </PivotViewEvents>
</SfPivotView>

@code {
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();

    void OnHyperlinkClick(HyperCellClickEventArgs args)
    {
        // args.CurrentCell contains the clicked cell info
        Console.WriteLine($"Clicked: {args.CurrentCell.Value}");
    }
}

`PivotViewHyperlinkSettings` properties:

---

Tooltip

Tooltips show contextual information (row/column headers + value) when hovering over value cells. Enabled by default.

<!-- Show tooltip (default: true) -->
<SfPivotView TValue="ProductDetails" ShowTooltip="true">

<!-- Disable tooltip for better performance on large datasets -->
<SfPivotView TValue="ProductDetails" ShowTooltip="false">

Performance tip: Disable tooltips (ShowTooltip="false") when using EnableVirtualization="true" — toggling the tooltip on large virtualized datasets can cause minor re-render overhead.

Overview

The Syncfusion Blazor Pivot Table supports OLAP (Online Analytical Processing) data sources, enabling users to analyze multidimensional data from OLAP cubes like Microsoft SQL Server Analysis Services (SSAS). OLAP provides powerful capabilities for complex data analysis, including hierarchies, calculated members, named sets, and MDX expressions.

When to Use OLAP:

• Connecting to Microsoft SQL Server Analysis Services (SSAS)
• Working with multidimensional cubes
• Analyzing data with complex hierarchies
• Using pre-defined calculated measures and dimensions
• Leveraging named sets and MDX expressions

---

Getting Started with OLAP

Basic OLAP Connection

To connect to an OLAP data source, configure PivotViewDataSourceSettings with OLAP-specific properties:

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails" Width="800" Height="350">
    <PivotViewDataSourceSettings TValue="ProductDetails" 
                                 ProviderType="ProviderType.SSAS" 
                                 Catalog="Adventure Works DW 2008 SE" 
                                 Cube="Adventure Works" 
                                 Url="https://bi.syncfusion.com/olap/msmdpump.dll" 
                                 LocaleIdentifier="1033" 
                                 EnableSorting="true">
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    public class ProductDetails
    {
        public int Sold { get; set; }
        public double Amount { get; set; }
        public string Country { get; set; }
        public string Products { get; set; }
        public string Year { get; set; }
        public string Quarter { get; set; }
    }
}

---

OLAP Data Binding

Required Properties

Configure these properties in PivotViewDataSourceSettings to bind OLAP data:

Complete OLAP Binding Example

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails" Width="800" Height="350">
    <PivotViewDataSourceSettings TValue="ProductDetails" 
                                 ProviderType="ProviderType.SSAS" 
                                 Catalog="Adventure Works DW 2008 SE" 
                                 Cube="Adventure Works" 
                                 Url="https://bi.syncfusion.com/olap/msmdpump.dll" 
                                 LocaleIdentifier="1033" 
                                 EnableSorting="true">
        <PivotViewColumns>
            <PivotViewColumn Name="[Product].[Product Categories]" Caption="Product Category"></PivotViewColumn>
            <PivotViewColumn Name="[Measures]" Caption="Measure"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="[Customer].[Customer Geography]" Caption="Customer Geography"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="[Measures].[Customer Count]" Caption="Customer Count"></PivotViewValue>
            <PivotViewValue Name="[Measures].[Internet Sales Amount]" Caption="Internet Sales Amount"></PivotViewValue>
        </PivotViewValues>
        <PivotViewFormatSettings>
            <PivotViewFormatSetting Name="[Measures].[Internet Sales Amount]" Format="C0"></PivotViewFormatSetting>
        </PivotViewFormatSettings>
    </PivotViewDataSourceSettings>
    <PivotViewGridSettings ColumnWidth="160"></PivotViewGridSettings>
</SfPivotView>

---

OLAP Cube Elements

OLAP cubes contain several types of elements that can be used in the Pivot Table:

Element Types

1. Measures: Numeric values for analysis (e.g., Sales Amount, Customer Count) 2. Dimensions: Categorical data (e.g., Product, Customer, Date) 3. Hierarchies: Parent-child relationships within dimensions 4. Levels: Specific stages within hierarchies 5. Named Sets: Predefined groups of members 6. Calculated Members: Custom calculations defined in the cube

OLAP Naming Convention

OLAP cube elements use MDX naming syntax:

• [Dimension].[Hierarchy] - Hierarchy reference
• [Dimension].[Hierarchy].[Level] - Level reference
• [Measures].[Measure Name] - Measure reference

Example:

[Product].[Product Categories]
[Customer].[Customer Geography]
[Measures].[Internet Sales Amount]

---

Adding Cube Elements to Axes

Specifying Cube Elements

Each OLAP cube element must be specified using:

• Name: Unique name from the cube (exact match required)
• Caption: Display label (optional, defaults to Name if not specified)

Four Axes Configuration

<PivotViewDataSourceSettings TValue="ProductDetails" 
                             ProviderType="ProviderType.SSAS" 
                             Catalog="Adventure Works DW 2008 SE" 
                             Cube="Adventure Works" 
                             Url="https://bi.syncfusion.com/olap/msmdpump.dll">
    
    <!-- Columns: Dimensions/Hierarchies displayed as columns -->
    <PivotViewColumns>
        <PivotViewColumn Name="[Product].[Product Categories]" Caption="Product Category"></PivotViewColumn>
        <PivotViewColumn Name="[Measures]" Caption="Measure"></PivotViewColumn>
    </PivotViewColumns>
    
    <!-- Rows: Dimensions/Hierarchies displayed as rows -->
    <PivotViewRows>
        <PivotViewRow Name="[Customer].[Customer Geography]" Caption="Customer Geography"></PivotViewRow>
    </PivotViewRows>
    
    <!-- Values: Measures for aggregation -->
    <PivotViewValues>
        <PivotViewValue Name="[Measures].[Customer Count]" Caption="Customer Count"></PivotViewValue>
        <PivotViewValue Name="[Measures].[Internet Sales Amount]" Caption="Internet Sales Amount"></PivotViewValue>
    </PivotViewValues>
    
    <!-- Filters: Master filters for the entire table -->
    <PivotViewFilters>
        <PivotViewFilter Name="[Date].[Fiscal]" Caption="Date Fiscal"></PivotViewFilter>
    </PivotViewFilters>
</PivotViewDataSourceSettings>

Critical: If the Name does not exactly match the cube element name, the Pivot Table will be empty.

---

Measures in Row Axis

By default, measures appear in columns. To display measures in rows:

<PivotViewRows>
    <PivotViewRow Name="[Customer].[Customer Geography]" Caption="Customer Geography"></PivotViewRow>
    <PivotViewRow Name="[Measures]" Caption="Measures"></PivotViewRow>
</PivotViewRows>

Users can also drag the "Measures" button between axes using the grouping bar or field list at runtime.

---

Named Sets

Named sets are predefined MDX expressions that return a group of dimension members.

Using Named Sets

Set IsNamedSet="true" when adding a named set:

<PivotViewColumns>
    <PivotViewColumn Name="[Core Product Group]" 
                     Caption="Core Product Group" 
                     IsNamedSet="true"></PivotViewColumn>
    <PivotViewColumn Name="[Measures]" Caption="Measures"></PivotViewColumn>
</PivotViewColumns>

Named sets can only be added to row or column axes, not to values or filters.

---

Calculated Fields

Create custom calculations based on existing cube elements.

Types of Calculated Fields

1. Calculated Measure: New measure from an expression 2. Calculated Dimension: New dimension from an expression

Defining Calculated Fields in Code

        <!-- Calculated Measure -->
        <PivotViewCalculatedFieldSetting 
            Name="Order on Discount" 
            Formula="[Measures].[Order Quantity] + ([Measures].[Order Quantity] * 0.10)" 
            FormatString="Currency">
        </PivotViewCalculatedFieldSetting>
    </PivotViewCalculatedFieldSettings>
</PivotViewDataSourceSettings>

Calculated Field Properties

Enable Calculated Field UI

Allow users to create calculated fields at runtime:

<SfPivotView TValue="ProductDetails" 
             ShowFieldList="true" 
             AllowCalculatedField="true">

This adds a "CALCULATED FIELD" button in the field list UI.

Format String Options

• Standard: Display as numbers (e.g., 9584.3)
• Currency: Display with currency symbol (e.g., $9,584.30)
• Percent: Display as percentage (e.g., 95.84%)
• Custom: Define custom format (e.g., "###0.##0#" → 9584.300)

Supported MDX Operators and Functions

Calculated fields support standard MDX operators and functions. See Microsoft documentation:

• MDX Operators
• MDX Functions

Example Formula:

IIF([Measures].[Internet Sales Amount]^0.5 > 100, 
    [Measures].[Internet Sales Amount]*100, 
    [Measures].[Internet Sales Amount]/100)

Note: Calculated measures can only be added to the value axis.

Authentication

Provide credentials for secure OLAP connections:

<PivotViewDataSourceSettings TValue="ProductDetails" 
                             ProviderType="ProviderType.SSAS" 
                             Catalog="Adventure Works DW 2008 SE" 
                             Cube="Adventure Works" 
                             Url="https://bi.syncfusion.com/olap/msmdpump.dll">
    
    <PivotViewAuthentication UserName="YourUsername" Password="YourPassword"></PivotViewAuthentication>
    
    <!-- Other settings... -->
</PivotViewDataSourceSettings>

If authentication is not provided in code, the browser displays a default login popup.

---

Roles

Assign SSAS roles to control data access:

<PivotViewDataSourceSettings TValue="ExpandoObject" 
                             ProviderType="ProviderType.SSAS" 
                             Catalog="Adventure Works DW 2008 SE" 
                             Cube="Adventure Works" 
                             Url="https://bi.syncfusion.com/olap/msmdpump.dll" 
                             Roles="Role1,Role2">
    
    <PivotViewAuthentication UserName="YourUsername" Password="YourPassword"></PivotViewAuthentication>
    
    <!-- Other settings... -->
</PivotViewDataSourceSettings>

Multiple Roles: Specify as comma-separated string: "Role1,Role2,Role3"

Roles control which cube data users can access based on SSAS security configuration.

---

Field List with OLAP

Enable the field list to allow runtime OLAP cube exploration:

<SfPivotView TValue="ProductDetails" ShowFieldList="true" Width="800" Height="350">
    <PivotViewDataSourceSettings TValue="ProductDetails" 
                                 ProviderType="ProviderType.SSAS" 
                                 Catalog="Adventure Works DW 2008 SE" 
                                 Cube="Adventure Works" 
                                 Url="https://bi.syncfusion.com/olap/msmdpump.dll">
        <!-- Axes configuration... -->
    </PivotViewDataSourceSettings>
</SfPivotView>

The field list displays:

• Dimensions with their hierarchies
• Measures
• Named sets
• Calculated members
• Display folders (organizational containers)

Users can drag cube elements between axes and apply filters/sorting.

---

Grouping Bar with OLAP

Enable the grouping bar for quick axis management:

<SfPivotView TValue="ProductDetails" ShowGroupingBar="true" Width="800" Height="350">
    <PivotViewDataSourceSettings TValue="ProductDetails" 
                                 ProviderType="ProviderType.SSAS" 
                                 Catalog="Adventure Works DW 2008 SE" 
                                 Cube="Adventure Works" 
                                 Url="https://bi.syncfusion.com/olap/msmdpump.dll">
        <!-- Axes configuration... -->
    </PivotViewDataSourceSettings>
</SfPivotView>

Users can drag cube elements between row, column, value, and filter axes directly.

---

Filter Axis

The filter axis acts as a master filter controlling data displayed across all other axes:

<PivotViewFilters>
    <PivotViewFilter Name="[Date].[Fiscal]" Caption="Date Fiscal"></PivotViewFilter>
</PivotViewFilters>

Use Filter Axis For:

• Dimensions that should filter the entire table
• Hierarchies that don't need to be displayed as rows/columns
• Calculated members used for filtering

Users can modify filter selections through the field list or grouping bar at runtime.

---

Virtual Scrolling with OLAP

Enable virtual scrolling for large OLAP datasets:

<SfPivotView TValue="ProductDetails" 
             Width="800" 
             Height="350" 
             EnableVirtualization="true" 
             ShowGroupingBar="true">
    <PivotViewDataSourceSettings TValue="ProductDetails" 
                                 ProviderType="ProviderType.SSAS" 
                                 Catalog="Adventure Works DW 2008 SE" 
                                 Cube="Adventure Works" 
                                 Url="https://bi.syncfusion.com/olap/msmdpump.dll">
        <PivotViewColumns>
            <PivotViewColumn Name="[Product].[Product Categories]"></PivotViewColumn>
            <PivotViewColumn Name="[Measures]"></PivotViewColumn>
        </PivotViewColumns>
        <PivotViewRows>
            <PivotViewRow Name="[Customer].[Customer]" Caption="Customer"></PivotViewRow>
        </PivotViewRows>
        <PivotViewValues>
            <PivotViewValue Name="[Measures].[Customer Count]"></PivotViewValue>
            <PivotViewValue Name="[Measures].[Internet Sales Amount]"></PivotViewValue>
        </PivotViewValues>
    </PivotViewDataSourceSettings>
    <PivotViewGridSettings ColumnWidth="160"></PivotViewGridSettings>
</SfPivotView>

Virtual Scrolling Limitations with OLAP

1. Column Width: Must be specified in pixels (not percentage) in PivotViewGridSettings 2. Totals Display: Subtotals and grand totals appear only when measures are at the end of rows or columns 3. Column Resizing: Affects scrolling calculations 4. Performance: Large width/height values increase data loaded per page

OLAP Cube Elements Reference

Field List Node Types

The OLAP field list displays different icons for each element type:

Hierarchies

User-Defined Hierarchy:

• Contains 2+ levels
• Example: Date → Year → Quarter → Month
• Allows drill-down navigation

Attribute Hierarchy:

• Contains single level
• Each dimension field creates one
• Example: Country (single level)

Measures

Measures are numeric values from the cube's fact table. Always displayed under the "Measures" dimension in the field list.

Adding to Values Axis:

<PivotViewValues>
    <PivotViewValue Name="[Measures].[Internet Sales Amount]" Caption="Sales"></PivotViewValue>
</PivotViewValues>

Applying Formatting:

<PivotViewFormatSettings>
    <PivotViewFormatSetting Name="[Measures].[Internet Sales Amount]" Format="C0"></PivotViewFormatSetting>
</PivotViewFormatSettings>

Dimensions

Dimensions organize data into categories. Each dimension can contain:

• Multiple hierarchies (user-defined and attribute)
• Levels within hierarchies
• Members and child members
• Named sets
• Calculated members

Levels

Levels represent stages within a hierarchy:

Customer Geography Hierarchy:
  Level 1: Country
  Level 2: State
  Level 3: City

Each level can be added independently to axes for specific granularity.

Common Patterns

Pattern 1: Basic OLAP Connection

<SfPivotView TValue="ProductDetails">
    <PivotViewDataSourceSettings TValue="ProductDetails" 
                                 ProviderType="ProviderType.SSAS" 
                                 Catalog="Your Catalog" 
                                 Cube="Your Cube" 
                                 Url="https://your-server/olap/msmdpump.dll">
    </PivotViewDataSourceSettings>
</SfPivotView>

Pattern 2: OLAP with Field List and Grouping Bar

<SfPivotView TValue="ProductDetails" 
             ShowFieldList="true" 
             ShowGroupingBar="true">
    <PivotViewDataSourceSettings TValue="ProductDetails" 
                                 ProviderType="ProviderType.SSAS" 
                                 Catalog="Adventure Works DW 2008 SE" 
                                 Cube="Adventure Works" 
                                 Url="https://bi.syncfusion.com/olap/msmdpump.dll">
    </PivotViewDataSourceSettings>
</SfPivotView>

Pattern 3: OLAP with Authentication and Roles

<PivotViewDataSourceSettings TValue="ExpandoObject" 
                             ProviderType="ProviderType.SSAS" 
                             Roles="AnalystRole,ViewerRole">
    <PivotViewAuthentication UserName="analyst1" Password="SecurePass123"></PivotViewAuthentication>
</PivotViewDataSourceSettings>

Pattern 4: OLAP with Calculated Fields

<SfPivotView TValue="ProductDetails" 
             ShowFieldList="true" 
             AllowCalculatedField="true">
    <PivotViewDataSourceSettings TValue="ProductDetails" 
                                 ProviderType="ProviderType.SSAS" 
                                 Catalog="Adventure Works DW 2008 SE" 
                                 Cube="Adventure Works" 
                                 Url="https://bi.syncfusion.com/olap/msmdpump.dll">
        <PivotViewCalculatedFieldSettings>
            <PivotViewCalculatedFieldSetting 
                Name="DiscountedAmount" 
                Formula="[Measures].[Sales Amount] * 0.9" 
                FormatString="Currency">
            </PivotViewCalculatedFieldSetting>
        </PivotViewCalculatedFieldSettings>
    </PivotViewDataSourceSettings>
</SfPivotView>

Troubleshooting

Empty Pivot Table

• Cause: Incorrect cube element names
• Solution: Verify exact names from SSAS using SQL Server Management Studio or field list

Authentication Popup

• Cause: Missing authentication in code
• Solution: Add PivotViewAuthentication with credentials

Missing Totals with Virtual Scrolling

• Cause: Measures not at end of rows/columns
• Solution: Place [Measures] as last item in row or column axis

Calculated Field Not Showing

• Cause: IsCalculatedField not set or wrong axis
• Solution: Set IsCalculatedField="true" and ensure calculated measures are in values axis

Role Access Denied

• Cause: SSAS role doesn't grant access to cube
• Solution: Verify role permissions in SSAS or use different role

Key Properties Summary

PDF Export — Syncfusion Blazor Pivot Table

PDF export allows you to generate high-quality PDF documents from the pivot table with customizable page orientation, themes, and formatting.

PDF Export

Enable with AllowPdfExport="true" and call ExportToPdfAsync():

@using Syncfusion.Blazor.PivotView
@using Syncfusion.Blazor.Buttons

<SfButton OnClick="OnPdfExport" Content="Export to PDF"></SfButton>

<SfPivotView TValue="ProductDetails" @ref="pivot" AllowPdfExport="true">
    <PivotViewDataSourceSettings DataSource="@data">
        ...
    </PivotViewDataSourceSettings>
</SfPivotView>

@code {
    SfPivotView<ProductDetails> pivot;
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized() => data = ProductDetails.GetProductData().ToList();

    public void OnPdfExport() => pivot.ExportToPdfAsync();
}

PDF Export with Customization

Page Orientation and Theme

@code {
    public async Task OnPdfExport()
    {
        var exportProperties = new PdfExportProperties
        {
            FileName = "SalesReport.pdf",
            PageOrientation = PageOrientation.Landscape,
            Theme = new PdfTheme
            {
                Header = new PdfThemeStyle { Bold = true, FontSize = 14 },
                Record = new PdfThemeStyle { FontSize = 10 }
            }
        };
        await pivot.ExportToPdfAsync(exportProperties);
    }
}

Export Chart with Table

When both the pivot grid and pivot chart are visible, export them together:

<SfPivotView TValue="ProductDetails" @ref="pivot"
             AllowPdfExport="true" AllowExcelExport="true">
    <PivotViewDisplayOption View="View.Both" Primary="Primary.Table">
    </PivotViewDisplayOption>
    ...
</SfPivotView>

@code {
    // Export both grid and chart to PDF on the same page
    public void ExportAll() => pivot.ExportToPdfAsync();
}

Export as Memory Stream

Pass true to get a MemoryStream instead of downloading — useful for server-side file generation or email attachments:

@code {
    public async Task ExportToStream()
    {
        // Returns MemoryStream — save to disk, email, or upload to storage
        MemoryStream stream = await pivot.ExportToPdfAsync(true) as MemoryStream;
        // e.g., save to file:
        await File.WriteAllBytesAsync("output.pdf", stream.ToArray());
    }
}
