I see that after reordering cells in RadListView, the data is reordered automatically. That's pretty nice. I'm looking for a way to go the other direction. If I reorder the data programmatically, I'd like the interface to refresh so it reflects the order of the data. Is this possible with RadListView?

OK, I figured out I can update the sort descriptor of the list view to make the interface update. It works fine on iOS.

On Android, I'm having a separate problem. I can click and drag a row but the SelectionChanged event appears to not get invoked.

I have this in my MainActivity.cs as specified on the Getting Started page:

[assembly: ExportRenderer (typeof (Telerik.XamarinForms.DataControls.RadListView), typeof (Telerik.XamarinForms.DataControlsRenderer.Android.ListViewRenderer))]

Am I missing something?

Hello Greg,

Could you, please, refer to the answer we have provided in this forum post, which describes how to achieve this by subscribing to CollectionChanged. Does this provide the required behavior?
