Since map control does not implement track shape cancelling with Escape key like Desktop Edition 2.0, I implemented CustomTrackInteractiveOverlay (derived from the Wiki sample) to handle track shape cancellation and it is working great.
In my scenario I draw polygon and then place it right away into EditOverlay.EditShapeLayer.Internal features so it can be edited.
Everything works fine: I can add vertex, resize, rotate, and move.
When I try to delete a vertex from the polygon by mouse double-click, point does not go away.
I have sample application attached.
Any help would be helpful, may be I missed something...
Thank you.
