How to remove a MenuItem base on condition

There may be an easier solution, which is to use the MenuItemDataBound event. I use this to hide menu nodes from the Menu Controller . Keeping them in the siteMap allows them to appear in the Menu Controller, but I don't want them in the Menu Controller based on the Roles attribute . Here's my code:

The SiteMap File

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
    <siteMapNode url="" title=""  description="">
        <siteMapNode url="#" title="Home" roles="*"  description="This is Homepage" />
        <siteMapNode url="" title="About" roles="*"  description="This About Page" />
        <siteMapNode url="_#" title="Product" roles="ADMIN" description="This is Product Page, Only Role Admin Can access" />
    </siteMapNode>
</siteMap>

The ASPX Page

<br />
    <asp:Menu ID="NavigationMenu" runat="server" BackColor="#F7F6F3" DataSourceID="SiteMapDataSource1"
        DynamicHorizontalOffset="2" Font-Names="Verdana" Font-Size="0.8em" ForeColor="#7C6F57"
        StaticSubMenuIndent="10px">
        <DynamicHoverStyle BackColor="#7C6F57" ForeColor="White" />
        <DynamicMenuItemStyle HorizontalPadding="5px" VerticalPadding="2px" />
        <DynamicMenuStyle BackColor="#F7F6F3" />
        <DynamicSelectedStyle BackColor="#5D7B9D" />
        <StaticHoverStyle BackColor="#7C6F57" ForeColor="White" />
        <StaticMenuItemStyle HorizontalPadding="5px" VerticalPadding="2px" />
        <StaticSelectedStyle BackColor="#5D7B9D" />
    </asp:Menu>
    <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" SiteMapProvider="SitemapSys" />
    <br />

The Code Behind

 protected void Page_Load(object sender, EventArgs e)
 {
     if (!Page.IsPostBack)
     {
         NavigationMenu.MenuItemDataBound += new MenuEventHandler(NavigationMenu_MenuItemDataBound);
     }
 }
 void NavigationMenu_MenuItemDataBound(object sender, MenuEventArgs e)
 {
     SiteMapNode node = (SiteMapNode)e.Item.DataItem;
     if (node.Roles.Count > 0)
     {
         string accessLvl = node.Roles[0].ToString();
         string userLogInRoles = "ANONYMOUS";
         if ((userLogInRoles .Trim().ToUpper() != accessLvl.Trim().ToUpper()) && 
               accessLvl != "*" )
         {
             e.Item.Parent.ChildItems.Remove(e.Item);
         }
     }
 }

Web.Config

<siteMap>
      <providers>
        <add name="SitemapSys" type="System.Web.XmlSiteMapProvider" siteMapFile="~/Web.sitemap" />
      </providers>
    </siteMap>
