The auto-scroll feature was part of the RadDragAndDropManager
class and it was removed due to the issues it led to. However, as the RadTreeView
uses the RadDragAndDropManager
, the auto-scroll feature stopped working in it as well.
In future we plan to replace the old RadDragAndDropManager
and to replace it with the new and improved DragDropManager
. Once we do that, we'll add the auto-scroll feature as well.
In the meantime, the behavior approach you found is the best way to implement scroll during drag. And if you can send over a sample solution demonstrating the issues you found with it, we'll gladly take a closer look and assist you in overcoming them.
