I'm trying to set a starting height so that the buttons don't run off the bottom of the overflow area. Basically in my picture I need the treeview area to be smaller and the group buttons to move up. Basically the splitter is moved up an inch or two at run-time. I can move the splitter up at design time but not as much as I need. I've tried just about every property at r/t and can't seem to get it right.

 Any help is appreciated.
