It is possible to drag and drop nodes from one radtreeview to other but no having the ability to do the reverse. furthermore i want to have the possibility to drag and drop between nodes just in the other radtreeview.
Example : RadTreeView1 -> just possibility to drag and drop in Radtreeview2
Regarding the need to disable the drag from the RadTreeView2 to RadTreeView1 - you can use the onNodeDropping client-side event. Then in you can get the ID of the source TreeView, using the sender.get_id(). and the destination, using dest.get_treeView().get_id(). If the attempt of draging is TreeView2->TreeView1 you can cancel the event, using the eventArguments: args.set_cancel(true);
As for the Drag&Drop between nodes - you can use the property EnableDragAndDropBetweenNodes regarding the desired behavior for each TreeView.
Hope this information helps.
