I have a user control A in which a RadTreeview is added and another user control B which hold a RadListView. I am looking a way to implement drag items from B to A I used the onitemdrop event of listview, but the same is showing destinationhtmlelement as null when dropped on to the treeview of A. Also the onnodedropped event of treeview in A is not firing when i dropped from B to A. Can some one explain how can I implement this?
