  Is there a doc anywhere that lists all the treeNode get methods? Basically I need to pull an attribute out of the selected node and I have been unable to get to it. The only things that seem to work are get_text() and get_value(). Neither of which help me.
  
  Thanks.

  Hello James,
  
  You can use the get_attributes() method of RadTreeNode object to get the collection of all custom attributes set to the Node. See the example shown below:
  
  ASPX:
  

  <telerik:RadTreeView ID="RadTreeView1"  runat="server" OnClientNodeClicked="onNodeClicked">

  <Nodes>

  <telerik:RadTreeNode runat="server" Text="BMW" CategoryOf="Car">

  </telerik:RadTreeNode>

  <telerik:RadTreeNode runat="server" Text="Red" CategoryOf="Color">

  </telerik:RadTreeNode>

  <telerik:RadTreeNode runat="server" Text="Mango" CategoryOf="Fruit">

  </telerik:RadTreeNode>

  </Nodes>

  </telerik:RadTreeView>

  
  JavaScript:
  

  <script language="javascript" type="text/javascript">

  function onNodeClicked(sender, args)

  {

  var node = args.get_node();

  alert(node.get_attributes().getAttribute("CategoryOf"));

  //you can also set attributes, like:

  //node.get_attributes().setAttribute("CategoryOf");

  }

  </script>

  
  Go through the following link which lists the most important functions of the RadTreeNode object.
