How to get selected TreeNode in JavaScript?

[dbassett74]

Rather than setting which menu items are visible with an AjaxMethod which requires a round trip to the server, I rather do it entirely client side in JavaScript. But I can't seem to get a reference to the selected node. Here is what I have so far, but the SetMenu() is not working:

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="FolderViewPanel.ascx.vb" Inherits="FolderViewPanel" %>
<%@ Register Assembly="Coolite.Ext.Web" Namespace="Coolite.Ext.Web" TagPrefix="ext" %>

<script type="text/javascript">
    function SetMenu(node) {
        Ext.Msg.alert('Selected Node Id', FolderViewMenu.node.id);
    }
</script>

<ext:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">
</ext:ScriptManagerProxy>

 <ext:Menu ID="FolderViewMenu" runat="server">
    <Items>
        <ext:MenuItem ID="mnuPrint" runat="server" Text="Print/Plot..." Icon="Printer">
        </ext:MenuItem>
        <ext:MenuSeparator ID="mnuActivityLogSep" runat="server"></ext:MenuSeparator>
        <ext:MenuItem ID="mnuActivityLog" runat="server" Text="Activity Log..." Icon="Table">
            <Listeners>
                <Click Handler="Coolite.AjaxMethods.ShowActivityLog('test');" />
            </Listeners>         
        </ext:MenuItem>                         
    </Items>
    <Listeners>
        <BeforeShow Fn="SetMenu" />
    </Listeners>
</ext:Menu>

<ext:FitLayout runat="server">
    <ext:TreePanel ID="TreePanel1" runat="server" Border="false" Animate="false" AutoScroll="true">
        <Listeners>
            <BeforeLoad Fn="nodeLoad" />
            <Click Handler="Coolite.AjaxMethods.SetSelectedFolder(node.id);" />              
            <ContextMenu Handler="#{FolderViewMenu}.node = node; node.select(); #{FolderViewMenu}.showAt(e.getXY());" />
        </Listeners>
    </ext:TreePanel>
</ext:FitLayout>

Hi,

#{TreePanel1}.getSelectionModel().getSelectedNode()
