I have a tabbed MDI app and want its initial apperance to be horizontally split with the lower region having a height of 100. I can't do this in XAML because I have a menu pick that restores this default arrangement, so it has to be done programmatically. After I use MoveToNewHorizontalContainer to establish the split, how do I set the height of the lower window to 100?
