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

Hello Kev,

Yes, you can achieve the desired functionality. Please refer to the following online demo, where the basics of the drag&drop between TreeViews and other elements is demonstrated.

http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/draganddropnodes/defaultcs.aspx

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.

Regards,
