title: Ribbon Control Focus on button click
body: <p>I have a problem with the Microsoft Ribbon Control. If I have the focus in a Textbox and click a Button in the Ribbon menu, the focus still remains in the <code>Textbox</code>. And so the textbox property in my <code>ViewModel</code> does not get updated.</p>
  
  <p>I searched the web but did not find a solution. I tried setting <code>FocusManager.IsFocusScope</code> and <code>Focusable</code> of the <code>Ribbon</code> control with no effect.</p>
  
  <p>All I want is if the button is clicked the textbox looses focus.</p>
