I have 2 RadTreeViews. Users can drag from Tree A to Tree B. I had this working with RadDragAndDropManger, but an struggling to get it right with DragDropManager.
I'm trying to do the following 2 things, using DragDropManager:
1. When the user drags an item from Tree A onto Tree B, do a check based on properties of the item whether the item can be dropped, and cancel the drop if needed. (optionally, display as they are dragging that the item cannot be dropped in Tree B)
2. When an item is successfully dropped into Tree B, the item should still exist in Tree A.
