I am creating linked node graphics in DiagramView and at the end calling ZoomtToFit()

Now I dont want to show scrollbar as my graphics is within the screen, now I just want to set the DiagramView size to whatever ZoomtoFit size so the scrollbar will  not be shown, note I dont want to use autoscrollBar =false.

In short I want to set the size of my screen equal to the Final graphic size (i.e. After ZoomToFit()

thanks in advance
