title: How to use DockStyle.Fill for standard controls in WPF?
body: <p>I'm used from windows forms, that I create a panel, place controls inside it and give them <code>DockStyle.Fill</code> to max out their size to the surrounding panel.</p>
  
  <p>In WPF I want to have the same. I have a TabControl and I want its size to fill as much of the form as possible.
  I have a ribbon control (RibbonControlsLibrary) and want the rest of the form to be filled with the TabControl at max size.</p>
  
  <p>(I do not want to dock controls like docking in Visual Studio, just old docking mechanisms)</p>
