title: Binding to Dependency Property of Data Type Binding
body: <p>I have a dependency property in a custom control that is of type Binding.</p>
  
  <pre><code>public static readonly DependencyProperty DisplayMemberBindingProperty =
          DependencyProperty.Register(
          "Binding",
          typeof(Binding),
          typeof(CustomControl),
          new PropertyMetadata(OnDisplayMemberBindingChanged));
  </code></pre>
  
  <p>In one of my views that instantiates this custom control, I want to bind, doing the following:</p>
  
  <pre><code>&lt;local:CustomControl DisplayMemberBinding="{Binding Path=SomeRandomPropertyInMyViewModel}" /&gt;
  </code></pre>
  
  <p>Obviously what I'm trying to do won't work.  So, is it possible to bind to a Dependency Property of type Binding, and if so, how?</p>
  
  <p>Thanks!</p>
