Forces a complete redraw of the virtual display.
The Refresh method forces the control to redraw the virtual display. Normally, the virtual display is automatically redrawn after the display has been modified and there are no other events being processed. However, there may be situations where you want the display updated immediately.
To prevent the control from automatically redrawing the window when the virtual display has been modified, set the AutoRefresh property to false. You can then call the Refresh method to force the control to be redrawn as needed
