title: Binding to Converter Parameter
body: <p>Is it possible to bind to a ConverterParameter in Silverlight 4.0?</p>
  
  <p>For instance I would like to do something like this and bind the ConverterParameter to an object in a ViewModel for instance.</p>
  
  <p>If this is not possible are there any other options?</p>
  
  <pre><code>&lt;RadioButton
    Content="{Binding Path=Mode}"
    IsChecked="{Binding
      Converter={StaticResource ParameterModeToBoolConverter},
      ConverterParameter={Binding Path=DataContext.SelectedMode,ElementName=root}}"
  /&gt;
  </code></pre>
