Sets or gets value that determines if drag data will be moved, copied or either based on user preference when the drag and drop completes. If set to DragDropMode.Move, dragged data will always be moved when a drop occurs, meaning that the original source data will be removed from the source tree and then added to the destination tree. If set to DragDropMode.Copy, drag data will always be copied when a drop occurs, meaning that the original source data will be retained in the source tree and a copy of it will be added to the destination tree. By default this property is set to DragDropMode.Default.
