title: WPF: Disable arrow-keys on tabcontrol
body: <p>I'm using the WPF TabControl in my application in order to switch between different areas/functions of the program.</p>
  
  <p>One thing annoys me though. I have hidden the tabs so I can control the selectedtab, instead of the user. The user however, can still switch between tabs using the arrow-keys.</p>
  
  <p>I have tried using the KeyboardNavigation-attribute, but I can't get this working.</p>
  
  <p>Can this be disabled?</p>
