Implementing .NET MAUI ListView

A comprehensive skill for implementing, customizing, and optimizing the Syncfusion .NET MAUI ListView (SfListView) component. The ListView displays collections of data with support for layouts, sorting, filtering, grouping, selection, and rich customization options.

When to Use This Skill

Use this skill when you need to:

• Display Collections: Show lists of data items from any data source (ObservableCollection, List, etc.)
• Data Operations: Implement sorting, filtering, or grouping of list items
• Custom Layouts: Create linear or grid layouts with single or multiple columns
• User Interaction: Enable item selection (single/multiple), tapping, long-press, or double-tap
• Advanced Features: Add swipe actions, drag-and-drop reordering, pull-to-refresh, or load more
• Customization: Design custom item templates, headers, footers, or group headers
• Performance: Optimize list rendering for large datasets with virtualization
• MVVM Patterns: Implement ListView with data binding, commands, and ViewModels

Common Scenarios:

• Product catalogs, contact lists, inbox/email lists
• News feeds, social media posts, photo galleries
• Settings pages, navigation menus, file browsers
• Task lists, order history, transaction records
• Any scrollable collection of similar items

Component Overview

SfListView is a high-performance, feature-rich list control that:

• Renders data items using built-in or custom templates
• Supports optimized view reusing strategy for smooth scrolling
• Provides linear and grid layouts with orientation support
• Enables data operations (sort, filter, group) without re-binding
• Offers multiple selection modes and gestures
• Includes sticky headers, footers, and group headers
• Supports item swipe actions and drag-and-drop
• Handles large datasets efficiently with virtualization
