uses a TreeViewDragDropOptions
object to wrap all drag-drop related data during a drag operation. This is why if you create such an element in the DragInitialize
handler in the ListBox DragDropBehavior
implementation, as soon as you drag a ListBoxItem
over the RadTreeView
, the TreeViewDragDropOptions
will trigger the TreeView's
auto-expand, auto-scroll-during-drag and drag-over-visualization logic.
I attached a sample solution demonstrating this approach. Please have a look at it and let us know if it helps.
