I'm creating my own scrollbar which should be able to be bound to any control and scroll it as necessary (i.e. if the preferred size is greater than the shown size). My problem is that I cannot change the .top property of the bound control when scrollbar is used because the control is often docked and has anchors.
1) Is there some way around this without modifying the .top property?
2) How does an autoscroll Panel manage it when the child components have docked properties set?
