#Remarks
The TreeViewControl raises the ContinueRecordDrag event continuously while a user drags a record. You can handle this event to determine what action ends the drag-and-drop operation based on the state of the ESC, SHIFT, CTRL, and ALT keys, and the state of the mouse buttons.
The default handler for this event cancels the drag-and-drop operation if a user presses the ESC key, and drops the data if a user releases the mouse button.
For information about drag-and-drop operations, refer to the following DevExpress WPF Grid help topic: Drag-and-Drop.
