You can use this and the MouseLeave event to create rollover and mouseover behaviors as in DHTML.
A control receives a MouseEnter event when the user moves the mouse into a control from a mouse position that was previously outside the control. In the case of overlapping or intersecting controls, the topmost control in the z-order receives the event.
A MouseEnter event is passed to objects on forms or toolbars. Forms and toolbars themselves do not receive this event.
