[Solved] AJAX Event Filtering not working?

[Vme]

I'm trying to have my ajax loading panel only be used on certain events and to postback on others.  For example I want my treeview to use ajax for NodeExpanded/NodeCollapsed, but not for NodeClicked.  Her is my entire HTML.  Any suggestions would be great.

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="OUTreeview.ascx.cs"
    Inherits="OUTreeview" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<div>
    <telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="rtvDSMOU" EventName="rtvDSMOU_NodeExpand">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rtvDSMOU" LoadingPanelID="RadAjaxLoadingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManagerProxy>
    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Height="75px"
        Width="75px">
        <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>'
            style="border: 0px;" />
    </telerik:RadAjaxLoadingPanel>
    <telerik:RadTreeView ID="rtvDSMOU" runat="server" OnNodeExpand="rtvDSMOU_NodeExpand"
        BorderStyle="None" BorderWidth="0px" OnNodeCollapse="rtvDSMOU_NodeCollapse" OnNodeClick="rtvDSMOU_NodeClick"
        ShowLineImages="False">
        <CollapseAnimation Duration="100" Type="OutQuad" />
        <ExpandAnimation Duration="100" Type="InQuad" />
    </telerik:RadTreeView>
</div>

Hello Kyle,

Test the following approach:

<script type="text/javascript" language="javascript">
    var flag = false;
    function requestStart(sender, eventArgs)
    {
        if (flag)
            eventArgs.set_enableAjax(false);
    }
    function nodeClicking(sender, eventArgs)
    {
        flag = true;
    }
</script>

<ClientEvents OnRequestStart="requestStart" />
<AjaxSettings>

<telerik:RadTreeView ID="rtvDSMOU" runat="server" BorderStyle="None" BorderWidth="0px"
    OnClientNodeClicking="nodeClicking" ShowLineImages="False" OnNodeClick="rtvDSMOU_NodeClick"
    OnNodeCollapse="rtvDSMOU_NodeCollapse" OnNodeExpand="rtvDSMOU_NodeExpand">
