title: Constrain the movement of a SplitContainer in C#?
body: <p>I have a <code>SplitContainer</code> in my form.<br>
  On the 1st panel I have a <code>TreeView</code> and a <code>ListView</code> on the 2nd. (Classic)<br>
  Now I want to limit the size of the 1st panel (with the <code>TreeView</code>) to 250 pixels wide.<br>
  I wish to block the separator from moving too much (or too less).<br>
  How do I do that?</p>
