title: WP7 - Databind ListboxItem's IsEnabled Property
body: <p>I have a Listbox with its ItemsSource property databound to a collection of objects. Each of the objects in the collection have an <code>Enabled</code> property which I would like to bind to their respective ListboxItem. I tried this approach:</p>
  
  <pre><code>&lt;ListBox ItemsSource="{Binding MyList}"&gt;
      &lt;ListBox.ItemContainerStyle&gt;
          &lt;Style TargetType="ListBoxItem"&gt;
              &lt;Setter Property="IsEnabled" Value="{Binding Enabled}" /&gt;
          &lt;/Style&gt;
      &lt;/ListBox.ItemContainerStyle&gt;
  &lt;/ListBox&gt;
  </code></pre>
  
  <p>This results in AG_E_RUNTIME_MANAGED_UNKNOWN_ERROR failing on this line:</p>
  
  <pre><code>&lt;Setter Property="IsEnabled" Value="{Binding Enabled}" /&gt;
  </code></pre>
  
  <p>How do I bind to the IsEnabled property on ListboxItems (using Windows Phone 7)?</p>
