title: Binding a property to an integer
body: <p>I've been reading a lot tutorials but somehow nothing works they mention about binding a property to a simple integer.</p>
  
  <p>Here's the setup:</p>
  
  <p>I got a user-control.
  I want to bind "private int size" to the width of a border within the XAML-file.</p>
  
  <p>Whats the easiest way to do this? </p>
