title: Is there a free WinForms control similar to Telerik's RadDock?
body: <p>I'm looking to create an interface which has drag-drop-dock functionality like Visual Studio. Telerik offers exactly what I'm looking for:
  <a href="http://www.telerik.com/products/winforms/dock.aspx" rel="nofollow">http://www.telerik.com/products/winforms/dock.aspx</a></p>
  
  <p>Trouble is, it will cost $1000. This is a side project and I don't have a budget for that. Does anyone know of a similar control which is free and/or open source? Google didn't turn up any results.</p>
  
  <p>Thanks</p>
