# Implementing Syncfusion TypeScript ListView ## When to Use This Skill Use this skill when you need to: - Create lists with dynamic data (local, remote, or API-based) - Display hierarchical/nested list structures - Implement multi-select or checkbox-based selection - Add grouping, filtering, or search functionality - Build interactive UI components (chat windows, contact lists, data tables) - Apply custom templates and styling to list items - Enable advanced features like virtualization, drag-drop, animations, or paging - Handle list events (selection, scrolling, manipulation) ## Component Overview The **Syncfusion ListView** component is a feature-rich, high-performance list component for displaying data with support for: - **Data Binding**: Local arrays, remote APIs, dynamic data - **Selection**: Single, multiple, or checkbox-based selection - **Templating**: Custom item, header, and group templates - **Nesting**: Hierarchical structures with drill-down navigation - **Organization**: Grouping and filtering with searchable datasets - **Performance**: Virtual scrolling, efficient rendering for large datasets - **Interactivity**: Drag-drop, animations, events, custom styling - **Accessibility**: WCAG compliance, keyboard navigation, ARIA support ## Documentation and Navigation Guide ### Getting Started 📄 **Read:** [references/getting-started.md](references/getting-started.md) - Installation and package setup - Basic ListView implementation - CSS imports and theme configuration - First render and minimal working example - TypeScript project setup ### Data Binding & Sources 📄 **Read:** [references/data-binding.md](references/data-binding.md) - Local array data sources - Remote API data binding with DataManager - Dynamic data loading and refresh - Query builders and OData support - Real-world data binding patterns ### Templates & Rendering 📄 **Read:** [references/templates-rendering.md](references/templates-rendering.md) - Item templates (single-line, multi-line, custom HTML) - Header templates for custom headers - Group templates with styling - Dynamic template switching - Template best practices and patterns ### Selection & Interactions 📄 **Read:** [references/selection-interactions.md](references/selection-interactions.md) - Single-item selection - Multi-select with checkbox or Ctrl+click - Checkbox configuration and positioning - Enabling/disabling items - Item visibility toggling - Selection events and callbacks ### Nested Lists & Navigation 📄 **Read:** [references/nested-lists-navigation.md](references/nested-lists-navigation.md) - Hierarchical data structures - Nested list navigation and drill-down - Back navigation between levels - Breadcrumb patterns - Dynamic hierarchies ### Grouping & Filtering 📄 **Read:** [references/grouping-filtering.md](references/grouping-filtering.md) - Grouping items by category or field - Custom group header templates - Item count display in group headers - Search and filter implementation - Real-time filtering patterns ### Styling & Customization 📄 **Read:** [references/styling-customization.md](references/styling-customization.md) - CSS class customization - Theme application (Material, Fabric, Bootstrap) - Right-to-left (RTL) language support - Custom styling and CSS variables - Responsive design patterns ### Events & State Management 📄 **Read:** [references/events-state-management.md](references/events-state-management.md) - Available events (select, scroll, action begin/complete) - Event handling and callbacks - Event arguments and data - State tracking and management - Common event patterns ### Advanced Features 📄 **Read:** [references/advanced-features.md](references/advanced-features.md) - Virtual scrolling for large datasets - Paging and pagination integration - Drag-and-drop functionality - Animation effects and transitions - Persistence and state restoration - Performance optimization tips ### Real-World Examples & Use Cases 📄 **Read:** [references/use-case-examples.md](references/use-case-examples.md) - Chat window UI implementation - Contact list layout - Todo/task list application - Dual-list manager - Mobile contact layout - Grid-like layouts with ListView ### Complete API Reference 📄 **Read:** [references/api-reference.md](references/api-reference.md) - All ListView properties with types and defaults - Complete method documentation with parameters - Event definitions with argument structures - Type definitions and enums - Configuration interfaces - Usage examples for each major API item ## Quick Start Example ```typescript import { ListView, ListViewComponent } from '@syncfusion/ej2-lists'; import { DataBind } from '@syncfusion/ej2-base'; // Basic ListView with local data const listViewInstance = new ListView({ dataSource: [ { id: '1', text: 'Item 1' }, { id: '2', text: 'Item 2' }, { id: '3', text: 'Item 3' } ], fields: { id: 'id', text: 'text' } }); listViewInstance.appendTo('#element'); ``` ## Common Patterns ### Pattern 1: Basic List with Selection ```typescript const listView = new ListView({ dataSource: ['Apple', 'Banana', 'Cherry'], select: (args) => { console.log('Selected:', args.data); } }); listView.appendTo('#list'); ``` ### Pattern 2: Multi-Select with Checkboxes ```typescript const listView = new ListView({ dataSource: data, showCheckBox: true, fields: { text: 'Name', id: 'Id', isChecked: 'Checked' } }); listView.appendTo('#list'); ``` ### Pattern 3: Nested List Navigation ```typescript const listView = new ListView({ dataSource: hierarchicalData, fields: { text: 'text', id: 'id', child: 'child' }, select: (args) => { if (args.data.child) { // Navigate to child list } } }); listView.appendTo('#list'); ``` ### Pattern 4: Grouped List ```typescript const listView = new ListView({ dataSource: data, fields: { text: 'Name', groupBy: 'Category', id: 'Id' } }); listView.appendTo('#list');
