Hi,

I use RadTreeView to display the content in a hierarchical structure. An item in the tree is dragged onto another control which is working. The thing which I want to disable is altering the structure of the tree by dragging the items within the tree. How can I do this?

The tree items are bound to a collection & use ItemTemplate to display the items.

Thank you.

Hi Su,

You can attach a class handler for the tree view to DropQueryEvent of the RadDragAndDropManager (with last parameter true). In the attached handler you can implement the required logic to allow or forbid the drop operation. The attached project demonstrates described solution. Also, it contains a commented code which demonstrates a slightly different approach. You can employ this one that best fits your needs.

Please let us know if you need more info or the solution is not what you were looking for.

Sincerely yours,
