Syncfusion React Grid

The Syncfusion React Grid is a comprehensive, feature-rich component for displaying and manipulating tabular data. It provides extensive functionality for data binding, paging, sorting, filtering, grouping, editing, exporting, scrolling modes, row/column customization, and advanced state management to handle datasets of any size and complexity efficiently.

⚠️ Security & Trust Boundary

• The Grid skill does not perform any remote data access.
• All external API interaction is handled by a separate DataManager skill outside this skill’s trust boundary.

When to Use This Skill

Use the Syncfusion React Grid when you need to:

• Display tabular data with rows and columns in a React application
• Handle large datasets efficiently with paging, virtual scrolling, or infinite scrolling
• Enable sorting, filtering, and searching for single or multiple columns
• Edit data inline with multiple edit modes (Inline, Batch, Dialog)
• Export data to Excel or PDF formats with customization
• Group and aggregate data with summaries and calculations
• Customize rows and cells with templates and styling
• Manage complex column configurations (frozen columns, spanning, reordering, resizing)
• Optimize performance when rendering thousands of records
• Persist grid state for user preferences and configuration
• Provide responsive data views for different screen sizes

Component Overview

The Grid component provides:

• Data Binding: Support for local arrays, remote data sources, and DataManager integration
• Paging: Client-side pagination with customizable page size and navigation
• Sorting: Single and multi-column sorting with custom comparers
• Filtering: Multiple filter modes (Filter Bar, Filter Menu, Excel-like filter)
• Searching: Global search across columns
• Grouping: Group data by columns with aggregates and lazy loading
• Selection: Row, cell, and column selection with checkbox support
• Editing: Inline, Batch, and Dialog modes with validation and templates
• Aggregates: Sum, Average, Count, Min, Max with footer, group, and caption display
• Exporting: Excel and PDF export with templates and server-side support
• Scrolling: Standard, Virtual, and Infinite scrolling modes
• Row Customization: Templates, detail views, drag-drop, pinning, spanning
• Column Customization: Templates, resizing, reordering, freezing, spanning
• Performance: Optimized rendering for large datasets
• Responsive Design: Adaptive layouts for different screen sizes
• Module System: Feature-based modules to reduce bundle size

Mandatory Rules for Inbuilt API

CRITICAL: Follow these rules when using Grid's inbuilt API (137+ methods, 65+ events, 95+ properties):

Rule 1: Module Injection Required for Feature Methods

Methods only work if their module is injected. No error thrown if module missing.

Method	Required Module	Example
goToPage()	Page	<Inject services={[Page]} />
sortColumn()	Sort	<Inject services={[Sort]} />
filterByColumn()	Filter	<Inject services={[Filter]} />
addRecord(), deleteRecord()	Edit	<Inject services={[Edit]} />

Rule 2: Properties vs Methods - Know the Difference

• Properties: Set via JSX props (<GridComponent allowPaging={true} />)
• Methods: Call via ref (gridRef.current.goToPage(2))
• Can't set properties via methods or call methods via props

• Vertical rendering features: Supports paging, sorting, filtering, selection, dialog editing, aggregates, infinite scroll, and toolbar options.
• rowRenderingMode note: Column Menu (grouping, sorting, autofit, filter, column chooser) only works in Horizontal mode.
• AdaptiveUIMode property: Use "Mobile" to render adaptive layout only on mobile screens, or "Both" (default) for both mobile and desktop.
• Mobile screen optimization: Render adaptive dialogs and vertical layouts automatically when enableAdaptiveUI is enabled.

📄 Read: references/modules.md

• Grid module architecture and feature-based modules
• 30+ available modules and their dependencies
• Module injection patterns

Quick Start Example

import { ColumnDirective, ColumnsDirective, GridComponent, Inject, Page, Sort, Filter } from '@syncfusion/ej2-react-grids';

    CustomerID: 'TOMSP',
    EmployeeID: 6,

        <ColumnDirective field='OrderID' headerText='Order ID' width='100' textAlign='Right' />
        <ColumnDirective field='CustomerID' headerText='Customer' width='120' />
        <ColumnDirective field='OrderDate' headerText='Order Date' width='130' type='date' format='yMd' />
      </ColumnsDirective>
      <Inject services={[Page, Sort, Filter]} />
