Description

Describe the problem

Hi all, it would be nice to have an option to use DataGrid's SelectedItems in MVVM pattern also for setting selected items programatically, simillar to CollectionView in Xamarin. Now it is read only IList.

Describe the solution

Publish SelectedItems as ObservableCollection or some other type implementing some of observable patterns.

Research direction
Examine the DataGrid control source code in the repository to find the declaration of SelectedItems property (currently IList). Investigate how other observable properties are implemented in the toolkit. Consider any potential breaking changes or performance implications of switching to ObservableCollection.
