title: XAML Converter ConvertBack
body: <p>Is there a way to access the ConvertBack-Method of a Converter that implements IValueConverter directly from XAML?</p>
  
  <p>The basic situation is the following (relationsships):</p>
  
  <p><code>Route (1)&lt;-&gt;(CN) Training (1)&lt;-&gt;(CN) Kilometer</code></p>
  
  <p>The DataContext is set to a Training. From here I use the Convert-Method to access all my <code>Kilometers</code>. I also have a Converter from <code>Route</code> to <code>IList&lt;Training&gt;</code> and the ConvertBack would lookup the <code>Route</code> for a <code>Training</code>. But I seem to not be able to access that Method from XAML…</p>
