In the ListBoxDragDropBehavior documentation, it is said:
The ListBoxDragDropBehavior supports copying the dragged items if the Control key is pressed. For that purpose the CopyDraggedItems method should be overridden
But the behavior supports copying the dragged items without changing anything!
This is a problem because, in my case, I need to avoid the copying of the dragged items in all cases.
How can I do it?
