title: How to get an Element inside a RadPageView inside a RadMultiPage?
body: <p>I have html-code like this:  </p>
  
  <pre><code>&lt;telerik:RadMultiPage ID="MultiPage" runat="server"&gt;   
     &lt;telerik:RadPageView ID="TablePage" runat="server"&gt;  
        &lt;Cx:DataObjectDefinitionTree ID="TableOverview"   runat="server"/&gt;  
     &lt;/telerik:RadPageView&gt;  
  &lt;/telerik:RadMultiPage&gt;  
  </code></pre>
  
  <p>I can get the Multipage by this: <code>var multiPage = $find('&lt;%= MultiPage.ClientID %&gt;');</code><br>
  But i am not able to get either the <code>PageView</code> or the <code>DataObjectDefinitionTree</code>.<br>
  Though i need the <code>DataObjectDefinitionTree</code>.<br>
  I tried to get the <code>PageView</code> from the <code>MultiPage</code> and then the <code>DataObjectDefinitionTree</code> from that but that did not work either.  </p>
  
  <p>How can i get the <code>DataObjectDefinitionTree</code> into an Variable in Javascript?</p>
  
  <p>Edit:
  I just want to call two methods from <code>DataObjectDefinitionTree</code> (it is basicly the same as a <code>RadTreeView</code>).<br>
  These methods are <code>_getAllItems()</code> and <code>get_selectedNode()</code>.</p>
