title: How to insert top docked controls below previewsly top docked controls on a panel
body: <p>I use panel.controls.add to add controls to the panel. But... they insert at the very top of it.</p>
  
  <p>I tried the BringToFront and SendToBack methods, but does'nt seem to be working.</p>
  
  <p>Any ideas? Thanks</p>
  
  <p>EDIT:</p>
  
  <p>what i want, is that they dock at the top of the container, but if there is another docked control there, the new one is displayed below that one... </p>
