I have a WinForm containing a bindingNavigator at the top and a splitContainer with two horisontal panels below it. The splitContainer fills the space not occupied by the bindin
As pointed out by Lee:
Set the FixedPanel property to the panel you want to remain the same size.
This works like this:
teamSplitContainer.SplitterDistance = teamSplitContainer.Height - 100; teamSplitContainer.FixedPanel = FixedPanel.Panel2;
