I am using NodeTemplates in my RadTreeView and have set EnableDragAndDrop and EnableDragAndDropBetweenNodes to true, however, the lines used to indicate the dropzone between two nodes is not showing up.
Any tips or insight on on how I should go about debugging that?
Here I have attached a sample project with the scenario that you describe. It demonstrates that the line used to indicate the drop zone between nodes works just fine. However, if you need to drag and drop only a single control that is situated in a child node (or a node) and not the whole child node, then this is an option that we do not support. We only support DragAndDrop between nodes (or child nodes) and not just a single control that they may hold in the NodeTemplate.
