Examples

Tip

For more info, design guidance, and code examples, see Items repeater.

The WinUI 2 Gallery app includes interactive examples of most WinUI 2 controls, features, and functionality. Get the app from the Microsoft Store or get the source code on GitHub.

Remarks

While an ItemsRepeater can be used to present a basic set of items, it is typically just a building block for your own unique collection-based experiences, and is most often used as the display element in the template of a custom control.

ItemsRepeater supports virtualization when attached to a host that supports virtualization.
