title: How do I use the rendertransform of a templated control in the controltemplate
body: <p>In Silverlight 4:
  I'm converting a Usercontrol to a templated control. In my Usercontrol I had a RenderTransform</p>
  
  <pre><code>&lt;src:UserControlView.RenderTransform&gt;
      &lt;TransformGroup&gt;
          &lt;ScaleTransform/&gt;
          &lt;SkewTransform/&gt;
          &lt;RotateTransform/&gt;
          &lt;TranslateTransform X="-478" Y="-478"/&gt;
      &lt;/TransformGroup&gt;
  &lt;/src:UserControlView.RenderTransform&gt;
  </code></pre>
  
  <p>But now I'm in the Controltemplate I get an error message:</p>
  
  <p>Error 5 The attachable property 'RenderTransform' was not found in type 'MyControl'. ...\Themes\Generic.xaml</p>
  
  <pre><code>                &lt;local:MyControl.RenderTransform&gt;
                      &lt;TransformGroup&gt;
                          &lt;ScaleTransform /&gt;
                          &lt;SkewTransform /&gt;
                          &lt;RotateTransform /&gt;
                          &lt;TranslateTransform X="-478"
                                              Y="-478" /&gt;
                      &lt;/TransformGroup&gt;
                  &lt;/local:MyControl.RenderTransform&gt;
  </code></pre>
  
  <p>the local:MyControl is a desperate attempt 'cause I don't know how or where to look. My MyControl inherits from Control en there is a RenderTransform on UIElement so it somehow has to find it right?</p>
