Wait... so you can only set the scroll of a group that is directly on the card then? That makes it quite difficult to use... 

Where did you learn that the scrolling group can't be inside another group? I've just confirmed it using the effective layermode but I can't see it documented...

I think this means for scrolling fields in a custom control you need to set their height to the formatted height and then just scroll the group. I think I can workaround this for datagrids in mergDataGridScroller too...
