title: Control Docking Rectangle inside of a Panel
body: <p>I have a panel that renders a special header, this works all fine and good - but when I dock other controls inside of that panel, they size to fit underneath the header. </p>
  
  <p>My thought was to try and catch this and control it somewhere. Getting the DisplayArea doesn't work - then the header doesn't draw in the right place. Is there any way I can tell docking to account for the height of the header?</p>
  
  <p>Using C#, Windows Forms, .NET 3.5</p>
  
  <p>Panel : System.Windows.Forms.UserControl
  Header : System.Windows.Forms.UserControl</p>
  
  <p>Panel
  {
   Header { get; set; }
  }</p>
  
  <p>is the basic structure. It's not terribly complicated.</p>
