title: WPF Ribbon collapse and expand programmatically
body: <p>With the latest (October 2010) WPF Ribbon libraries, there exists a menu item to minimize/maximize (or collapse/expand, if you prefer) the ribbon control.</p>
  
  <p>Does anyone know if there's also a way to hook into the events that control this behaviour so that it could be controlled programmatically from separate UI?
  Or, better yet, is there a way to get a collapse/expand button to display in the ribbon like the 2010 Office apps do?</p>
