Drag and drop beetween rad tree view in on way

[Kev]

Hi,

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

 

    

 

but not being able to do the reverse

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.
