title: SplitContainer that only resizes panel1
body: <p>Is there a way to make the SplitContainer only adjust the size of panel1?  I have a Vertical SplitContainer and when I move the splitter I would like the size of the first panel to increase/decrease, but rather than change the size of the second panel I want the form to increase and decrease in size.  </p>
  
  <p>I created some code to increase/decrease the size of the form, but Panel2 is also changing size so the entire panel is not always visible.</p>
  
  <p>Am I going to have to make my own container, or is this possible with the SplitContainer?</p>
  
  <p>I have a form "MainWin" that contains a Panel "MainPanel" MainPanel contains the SplitContainer "MainSplitContainer".  Panel1 contains a TreeView, and Panel2 contains 3 Panels that are made visible based on which item is selected in the TreeView.  I want these 3 Panels to always be completely visible (I'm planning to limit the expansion of the splitter so the form cannot expand beyond the screen), is this possible or should I just create my own control and adjust the size of things using the MouseDown, MouseUp, and MouseMove events? </p>
