Provide an API for filtering the TreeView.

Imagine large list of expanded and collapsed items which completely does not fit on the screen in RadTreeView. User scrolls to the middle of the list. User doesn't select anything from the list, just looks. User closes the application, and the application saves TreeView's current scroll positions in some file. Next user opens the application. After items are loaded I want to scroll RadTreeView in code to the position from the previously saved data in file.

This is a feature request to include the Expand(item) and Collapse(item) methods that were available in Xamarin.Forms' TreeView.

This is a feature request to add events for when an item is expanded or when an item is collapsed.

Context menu would be useful to allow users to add / delete items.

Provide an option to load subitems only when they’re requested - load on demand

Provide an option to define the ItemTemplate on a TreeView Descriptor level. currently, the ItemTemplate is available on TreeView level.
