title: Caliburn Micro: How to bind ActivateItem to selectionEvents in Conductors
body: <p>As can be seen in the SimpleMDI Caliburn Micro project there are some conventions that bind the selectionEvent in tabControls to the ActivateItem in a Conductor. I can't really see any mention of what this event might be.</p>
  
  <p>However when you have a control that doesn't fullfill these convention I'm lost on how to manage them myself.</p>
  
  <p>I have a Telerik RadTreeView that I want to manage with a conductor to be able to load on demand the childs of nodes (via WCF call).</p>
  
  <p>Here is where I am at:</p>
  
  <pre><code>&lt;telerik:RadTreeView x:Name="Items"
                       cal:Message.Attach="[Event Selected] = [ActivateItem($dataContext)]"  /&gt;
  </code></pre>
  
  <p>Passing $dataContext is wrong because that way he passes the Conductor itself, $SelectedItem returns null.</p>
  
  <p>So my rather simple question is threefold.</p>
  
  <p>1) If RadTreeView is a Selecetor why doesn't the basic CM convention work with it,</p>
  
  <p>2) What event should I use to call ActiveItem</p>
  
  <p>3) What could I pass in.</p>
