Validating ASP menu Item

[Mongz]

Guys i need to validate a menu item on my ASP.NET application. The menu item has 4 links (Home, News, About us and Contact us) one of them "News" must not redirect to page if the user has not log on, the other three can redirect even if the user has'nt loggin or log in.
Please help with validating this process using C#

Add below code to aspx page

<asp:Menu ID="Menu1" runat="server"  Width="164px" OnMenuItemClick="Menu1_MenuItemClick" >
           <Items>
               <asp:MenuItem Text="Home" Value="Home" NavigateUrl="Home.aspx"></asp:MenuItem>
               <asp:MenuItem Text="News" Value="News" NavigateUrl="News.aspx"></asp:MenuItem>
               <asp:MenuItem Text="About Us " Value="About Us " NavigateUrl="AboutUs.aspx"></asp:MenuItem>
               <asp:MenuItem Text="Contact us" Value="Contact us" NavigateUrl="ContactUs.aspx"></asp:MenuItem>
           </Items>
       </asp:Menu>
        <asp:LoginStatus ID="LoginStatus1" runat="server" Style="z-index: 100; left: 39px;
            position: absolute; top: 185px" Width="116px" />

Add the below code to aspx.cs Page

protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)
    {
        if (Menu1.SelectedItem.Text == "News")
        {
            if (LoginStatus1.LoginText == "LogOut")
            {
                Menu1.SelectedItem.Enabled = false;
            }
        }
        else
        {
            Menu1.SelectedItem.Enabled = true;
        }
    }

The better way would be to enable security trimming in the web.sitemap or whichever xml file that you have used as a source to your menu.
