Implementing Syncfusion Blazor ListView Component

The Syncfusion Blazor ListView component is a feature-rich control for displaying and interacting with lists of data. It supports data binding, custom templates, grouping, filtering, virtualization, and advanced selection modes.

When to Use This Skill

Setting up ListView - Installation, namespaces, service registration, theme setup
Binding data - Local data arrays, remote DataManager sources, Entity Framework
Creating templates - Custom item templates, headers, footers, group headers, device-specific rendering
Selection & interaction - Checkbox selection, retrieving selected items, click handlers
Filtering & searching - Real-time search, text filtering, custom filter logic
Organizing data - Grouping by category, group headers, hierarchical grouping
Performance - Virtual scrolling for large datasets, container scroll vs window scroll
Advanced layouts - Grid layouts, dual-list patterns, chat UI, mobile-responsive designs
Styling & customization - CSS classes, themes, HTML attributes, responsive design
Event handling - Item selection, navigation, hyperlink integration, list events

Quick Start Example

cshtml

@using Syncfusion.Blazor.Lists

<SfListView DataSource="@ListData">
    <ListViewFieldSettings TValue="DataModel" Id="Id" Text="Text"></ListViewFieldSettings>
</SfListView>

@code {
    List<DataModel> ListData = new List<DataModel>();

    protected override void OnInitialized()
    {
        ListData.Add(new DataModel { Text = "Item 1", Id = "1" });
        ListData.Add(new DataModel { Text = "Item 2", Id = "2" });
        ListData.Add(new DataModel { Text = "Item 3", Id = "3" });
    }

    public class DataModel
    {
        public string Id { get; set; }
        public string Text { get; set; }
    }
}

Key Props Reference

Property	Type	Purpose
`DataSource`	Array/DataManager	Items to display
`HeaderTitle`	string	Header text
`ShowHeader`	bool	Show/hide header
`ShowCheckBox`	bool	Enable checkboxes
`EnableVirtualization`	bool	Virtual scrolling

Common Use Cases

Simple list display - Use basic DataSource binding with ListViewFieldSettings
Selectable lists - Add ShowCheckBox="true" with GetCheckedItemsAsync()
Searchable list - Bind TextBox input to filter DataSource in OnInput events
Grouped lists - Map GroupBy field in ListViewFieldSettings
Large datasets - Enable virtualization with EnableVirtualization="true" and Height
Custom UI - Use Template property with multi-line layouts, avatars, badges
Nested lists - Map Child field and use recursive templates
Responsive design - Device-specific templates or dynamic templates based on viewport
