title: C# WPF - Docked top and bottom but expandable middle section
body: <p>I have a WPF window with a Set on menu options on the top and a "Next" and "Previous" button on the bottom. In the middle of the window, I have a scroll viewer around a tab control in case the data in the tab control exceeds the window height. However, I would like to have m WPF move the buttons on the bottom and expand the middle if a user maximizes their window.</p>
  
  <p>Any suggestions on where to begin?</p>
