I have a MasterPage with a RadTreeView that I would like to use to navigate through a site by updating an ajaxed ContentPlaceHolder.  I have a regular asp:Panel wrapping a ContentPlaceHolder as is suggested but I'm still getting a full postback.  The ajax seems to kick off and Loading Panels show up, but they disappear well before the content is updated in a full postback.

I originally tried using the NavigateURL attribute of the RadTreeNode but it wouldn't initiate any Ajax at all, so instead I am tying into the OnNodeClick event and doing a RadAjaxManager.Redirect() call from there.  Any thoughts on why the Master is still posting back instead of just the content?

<?xml version="1.0" encoding="utf-8" ?> 
<Tree > 
 <Node PostBack="false" Text="Project Data" > 
    <Node Text="SingleProject Data" Expanded="False" PostBack="false" > 
      <Node Text="Home" NavigateURL="#" Value="Home.aspx"></Node> 
      <Node PostBack="false" Text="Project Management" > 
        <Node Text="Configuration" NavigateURL="#" Value="Configuration.aspx"></Node> 
      <Node PostBack="false" Text="Project Detail"
        <Node Text="Shipping" NavigateURL="#" Value="Shipping.aspx" /> 
        <Node Text="Building" NavigateURL="#" Value="Building.aspx" /> 
 protected void NodeClick(object sender, RadTreeNodeEventArgs e) 
            if (e.Node.NavigateUrl == "#"
<form id="form1" runat="server"
    <telerik:RadScriptManager ID="ScriptManager1" runat="server" EnableTheming="True"
    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1"
            <telerik:AjaxSetting AjaxControlID="RadTreeView1"
                    <telerik:AjaxUpdatedControl ControlID="pHeaderAjax" LoadingPanelID="RadAjaxLoadingPanel1" /> 
                    <telerik:AjaxUpdatedControl ControlID="pContentAjax" LoadingPanelID="RadAjaxLoadingPanel1" />

Hello Josh,

When navigating through the TreeView, are you redirecting to another page?
Note that ajax is used to update particular page content on the same page only. For a new page to be loaded a full postback should be performed.
