I am attempting to drag items from the RadTreeView to the RadScheduler. I do not want users to be able to drag items at the first level of the tree, so I attached a handler to the DragStarted event of the RadTreeView. Within that handler, I am checking the item being dragged, and if I don't want to allow dragging, I call RadDragAndDropManager.CancelDrag(). This is the same method used in the Scheduler drag and drop example. However, whenever CancelDrag gets called, it is causing the entire application to freeze. This appears to be the case in the example as well. You can drag items that are below the first level, but if you try to drag items at the first level, the application freezes. Please help me find a solution to this problem.
Thanks
