The Shift and Ctrl parameters indicate the current state of the SHIFT and CTRL keys respectively. They will be set to 1 if their respective keys are pressed.
The Cancel property is set to 0 before this event starts. If you want to prevent the user from dragging the items, set the Cancel property to 1.
