Implementing Syncfusion Blazor DataGrid

The Syncfusion Blazor DataGrid (SfGrid<TValue>) is a high-performance, feature-rich component for displaying and manipulating tabular data. It supports data binding, sorting, filtering, grouping, paging, editing, selection, aggregates, export, virtual/infinite scrolling, templates, and more.

NuGet: Syncfusion.Blazor.Grid + Syncfusion.Blazor.Themes Namespace: Syncfusion.Blazor.Grids

When to Use This Skill

Use this skill when you need to:

  • Set up and configure a DataGrid in Blazor Server, WebAssembly, Web App, or MAUI
  • Bind local or remote data (OData, HTTP, SfDataManager)
  • Configure columns (type, format, template, frozen, reorder, resize, chooser)
  • Implement sorting, filtering (FilterBar/Menu/Excel/CheckBox), or searching
  • Enable grouping with lazy load or caption templates
  • Configure paging with custom templates or SfPager
  • Set up virtual scrolling, infinite scrolling for large datasets
  • Implement editing (Normal/Dialog/Batch/Command column) with validation
  • Configure selection (row, cell, checkbox) with programmatic control
  • Use clipboard copy, AutoFill, or Paste features
  • Add aggregates (footer, group, caption, reactive)
  • Use row/column templates, detail template, row drag-drop
  • Configure toolbar, context menu, column menu, column chooser
  • Export data to Excel or PDF
  • Manage print functionality
  • Optimize performance (SetRowDataAsync, PreventRender)
  • Handle DataGrid events
  • Manage state persistence (EnablePersistence)
  • Customize styling and appearance
  • Enable adaptive UI for mobile/responsive layouts

🔒 Mandatory Key Rules

These rules govern how this skill MUST behave. They are mandatory and must be strictly followed.

1. Purpose and Responsibility

Your responsibility is to interpret any natural‑language user request and provide:

  • Accurate
  • Complete
  • Validated

information about all supported aspects of the Syncfusion Blazor DataGrid, including:

  • Public APIs
  • Properties
  • Events
  • Features
  • Behaviors

2. Accuracy and API Compliance

The Skill MUST:

  • Use only officially supported Syncfusion DataGrid features.
  • NEVER invent APIs, methods, properties, events, behaviors, or future features.
  • NEVER provide unsupported or hypothetical code samples.
  • ALWAYS follow official Syncfusion component design patterns.

If a feature is not supported:

  • Clearly state the limitation.
  • Suggest a supported alternative when possible.

3. Interpreting Natural-Language Requests

When user requests are incomplete:

  • Infer reasonable assumptions using official Grid best practices.
  • Fill missing gaps with accurate and relevant information.
  • Request clarification only when essential.

4. Response Quality Requirements

Every response MUST:

  • Be technically accurate
  • Be complete and well‑structured
  • Include required dependencies and configuration notes
  • Follow real, documented Syncfusion API behavior
  • Avoid contradictions or ambiguity

5. Handling Unsupported User Requests

If the user asks for an unsupported capability:

  • Explicitly state that it is not supported
  • Suggest official alternatives or valid workarounds
  • NEVER simulate or fabricate impossible functionality

6. Design Pattern Enforcement

The Skill MUST follow Syncfusion official patterns, including:

  • Correct component structure (SfGrid, GridColumn, GridEditSettings, etc.)
  • Proper async event and API usage
  • Valid configuration properties and enums
  • Supported data‑binding approaches
  • Real event patterns and names

7. Quality, Completeness & Reliability

The Skill MUST:

  • Use only validated and real Grid capabilities
  • Provide actionable and implementation‑ready guidance
  • Ensure clarity so users can follow without guesswork
  • Maintain clean, readable, and professional formatting

8. No-Hallucination Safeguard

The Skill MUST NOT:

  • Invent non‑existent APIs or behavior
  • Suggest unsupported modes, features, or configuration
  • Provide incorrect, misleading, or unverifiable code
  • Describe undocumented internal behavior

If unsure:

  • Ask for clarification OR
  • Clearly state the limitation

9. Event Name Verification Requirement

CRITICAL: Event names MUST be verified against references/events.md BEFORE providing code examples. All grid events MUST be defined inside the <GridEvents> component

Common Mistakes to Avoid:

  • ❌ OnSortChange - Does NOT exist. Use Sorting, Sorted instead
  • ❌ OnFilterChange - Does NOT exist. Use Filtering, Filtered instead
  • ❌ OnPageChange - Does NOT exist. Use PageChanging, PageChanged instead
  • ❌ OnGroupChange - Does NOT exist. Use Grouping, Grouped instead

Rule: ALWAYS cross-reference references/events.md for:

  • Exact event names (case-sensitive)
  • Event argument types
  • Whether events are cancelable
  • When they fire (before/after operation)

Verification Checklist Before Providing Event Code:

1. Check if event name exists in references/events.md 2. Verify the correct EventArgs type 3. Confirm Cancelable status (✅ or ❌) 4. Test against actual Syncfusion documentation 5. Never assume naming conventions (e.g., On prefix, Change suffix)

---

Strict Rules for Grid Events

1. Event Handlers MUST be in `<GridEvents>` Component

  • ✅ Define ALL event handlers inside <GridEvents TValue="YourType">
  • ✅ Use the exact event names as properties (e.g., DataBound, RowSelecting, Grouped)
  • ❌ DO NOT use @onEventName syntax on <SfGrid>
  • ❌ DO NOT define event handlers on any root element

2. Correct Event Handler Signatures

  • ✅ Use async Task for event handlers
  • ✅ Event handlers may have specific parameter types (e.g., GridEventArgs, RowSelectEventArgs)
  • ✅ Some events have no parameters (e.g., DataBound(), Created())
  • ❌ Do not use synchronous void methods for async operations

3. API Method Calls MUST NOT be in Lifecycle Events

  • ❌ DO NOT call API methods in OnInitialized()
  • ❌ DO NOT call API methods in OnAfterRenderAsync()
  • ❌ DO NOT call API methods in OnParametersSet()
  • ✅ ONLY call API methods in response to user interactions (button clicks, dropdown changes, etc.)
  • ✅ API methods CAN be called inside GridEvents handlers

4. Use Async/Await Pattern

  • ✅ Always use await with async API methods
  • ✅ Define event handlers as async Task
  • ✅ Mark code block methods as async Task
  • ❌ Do not use synchronous method calls for async operations

5. Grid Reference Required for API Calls

  • ✅ Use @ref="Grid" to get the Grid instance
  • ✅ Use the reference to call API methods (e.g., await Grid.GroupColumnAsync())
  • ❌ Do not attempt to call methods without a reference

6. Event Types Must Match GridEvents TValue

  • ✅ Set TValue="YourDataType" to match your data model
  • ✅ All event handlers will be properly typed with this model
  • ❌ Do not use generic or wrong type for TValue

Quick Start

@page "/datagrid-demo"
@using Syncfusion.Blazor.Grids

<SfGrid DataSource="@Orders" AllowPaging="true" AllowSorting="true" AllowFiltering="true">
    <GridPageSettings PageSize="10"></GridPageSettings>
    <GridColumns>
        <GridColumn Field="OrderID"    HeaderText="Order ID"   IsPrimaryKey="true" Width="120" TextAlign="TextAlign.Right"></GridColumn>
        <GridColumn Field="CustomerID" HeaderText="Customer"   Width="150"></GridColumn>
        <GridColumn Field="Freight"    HeaderText="Freight"    Format="C2" Width="120" TextAlign="TextAlign.Right"></GridColumn>
        <GridColumn Field="OrderDate"  HeaderText="Order Date" Format="d"  Width="150" Type="ColumnType.Date"></GridColumn>
        <GridColumn Field="ShipCountry" HeaderText="Ship Country" Width="150"></GridColumn>
    </GridColumns>
</SfGrid>

@code {
    public List<Order> Orders = new List<Order>
    {
        new Order { OrderID = 10248, CustomerID = "VINET", Freight = 32.38, OrderDate = new DateTime(1996,7,4), ShipCountry = "France" },
        new Order { OrderID = 10249, CustomerID = "TOMSP", Freight = 11.61, OrderDate = new DateTime(1996,7,5), ShipCountry = "Germany" },
    };
    public class Order
    {
        public int OrderID { get; set; }
        public string CustomerID { get; set; }
        public double Freight { get; set; }
        public DateTime OrderDate { get; set; }
        public string ShipCountry { get; set; }
    }
}

Common Patterns

Grid with Editing + Toolbar

<SfGrid DataSource="@Orders" Toolbar="@(new List<string>() { "Add","Edit","Delete","Update","Cancel" })">
    <GridEditSettings AllowAdding="true" AllowEditing="true" AllowDeleting="true" Mode="EditMode.Normal"></GridEditSettings>
    <GridColumns>
        <GridColumn Field="OrderID" IsPrimaryKey="true" ValidationRules="@(new ValidationRules{Required=true})"></GridColumn>
        <GridColumn Field="CustomerID" ValidationRules="@(new ValidationRules{Required=true})"></GridColumn>
        <GridColumn Field="Freight" EditType="EditType.NumericEdit"></GridColumn>
    </GridColumns>
</SfGrid>

Grid with Grouping + Paging

<SfGrid DataSource="@Orders" AllowGrouping="true" AllowPaging="true">
    <GridGroupSettings Columns="@(new string[]{"ShipCountry"})"></GridGroupSettings>
    <GridPageSettings PageSize="10"></GridPageSettings>
    <GridColumns>
        <GridColumn Field="OrderID" Width="120"></GridColumn>
        <GridColumn Field="CustomerID" Width="150"></GridColumn>
        <GridColumn Field="ShipCountry" Width="150"></GridColumn>
    </GridColumns>
</SfGrid>

Grid Reference for Programmatic Control

<SfGrid @ref="Grid" DataSource="@Orders">...</SfGrid>
@code {
    SfGrid<Order> Grid;
    // Programmatic operations:
    // await Grid.SortColumnAsync("OrderID", SortDirection.Ascending, false);
    // await Grid.FilterByColumnAsync("ShipCountry", "equal", "France");
    // await Grid.GoToPageAsync(2);
    // await Grid.StartEditAsync();
    // await Grid.SelectRowAsync(0);
}
