This is best done in the MenuItemDataBound     protected void NavigationMenu MenuItemDataBound object sender  MenuEventArgs e        if   Page User IsInRole  Admin                  if  e Item NavigateUrl Equals   admin                          if  e Item Parent    null                                MenuItem menu   e Item Parent                   menu ChildItems Remove e Item                             else                               Menu menu    Menu sender                   menu Items Remove e Item                                                    Because the example used the NavigateUrl it is not language specific and works on sites with localized site maps

I prefer to use the FindItem method and use the value path for locating the item   Make sure your PathSeparator property on the menu matches what you re using in FindItem parameter         protected void Page Load object sender  EventArgs e                    remove manage user accounts menu item for non-admin users          if   Page User IsInRole  Admin                          MenuItem item   NavigationMenu FindItem  Users Manage Accounts                item Parent ChildItems Remove item

You just have to remove the parent menu in the page init event       Protected Sub navMenu Init sender As Object  e As System EventArgs  Handles navMenu Init      Remove the admin menu for the norms     Dim cUser As Boolean   HttpContext Current User IsInRole  Admin         If user is not in the Admin role removes the 1st menu at index 0     If cUser   False Then         navMenu Items RemoveAt 0      End If End Sub

You can remove unwanted menu items in Page Load  like this       protected void Page Load object sender  EventArgs e                if   Roles IsUserInRole  Admin                          MenuItemCollection menuItems   mTopMenu Items              MenuItem adminItem   new MenuItem                foreach  MenuItem menuItem in menuItems                                if  menuItem Text     Roles                       adminItem   menuItem                            menuItems Remove adminItem                     I m sure there s a neater way to find the right item to remove  but this one works  You could also add all the wanted menu items in a Page Load method  instead of adding them in the markup

You can bind the menu items to a site map and use the roles attribute   You will need to enable Security Trimming in your Web Config to do this   This is the simplest way   Site Navigation Overview  http   msdn microsoft com en-us library e468hxky aspx  Security Trimming Info  http   msdn microsoft com en-us library ms178428 aspx  SiteMap Binding Info  http   www w3schools com aspnet aspnet navigation asp  Good Tutorial Overview here  http   weblogs asp net jgalloway archive 2008 01 26 asp-net-menu-and-sitemap-security-trimming-plus-a-trick-for-when-your-menu-and-security-don-t-match-up aspx  Another option that works  but is less ideal is to use the loginview control which can display controls based on role   This might be the quickest  but least flexible performant  option   You can find a guide here  http   weblogs asp net sukumarraju archive 2010 07 28 role-based-authorization-using-loginview-control aspx
