uno-toolkit-itemsrepeater-extensions

You can add selection to ItemsRepeater in XAML by binding attached properties like SelectionMode, SelectedItem, and SelectedIndex from the Uno Toolkit's ItemsRepeaterExtensions. This enables single or multiple selection capabilities directly in your XAML layout.

Yes, ItemsRepeater supports incremental loading on scroll when your data source implements ISupportIncrementalLoading. The Uno Toolkit extensions automatically trigger page loading as the user scrolls through the ItemsRepeater list.

The XAML namespace needed for ItemsRepeater selection extensions is xmlns:utu="using:Uno.Toolkit.UI". Declaring this utu namespace in your XAML page allows you to bind and consume the ItemsRepeaterExtensions properties.

Yes, you can bind multiple selected items in an ItemsRepeater using the utu:ItemsRepeaterExtensions.SelectedItems and utu:ItemsRepeaterExtensions.SelectedIndexes attached properties. Set SelectionMode to support multi-selection for this to work.

ItemsRepeater lacks built-in selection support because it is designed as a lightweight, performant layout control. The Uno Toolkit solves this by providing attached properties that inject selection and incremental loading behaviors without modifying the base control.

The best way to handle on-scroll data fetching in Uno Platform lists is combining ItemsRepeater with a data source implementing ISupportIncrementalLoading. The Uno Toolkit extensions automatically fetch subsequent data pages as users scroll to the bottom.
