Responds to the mouse button being held down over the lookup list.
The MouseDown method responds to the mouse button being held down over the lookup list. As the user presses a mouse button while within the lookup list, this method is called repeatedly. MouseDown generates an OnMouseDown event.
The Button parameter specifies which mouse button was pressed. The Shift parameter indicates which keys (Shift, Ctrl, and Alt) were down when the mouse button was pressed. X and Y indicate the new position of the mouse pointer.
