Show menu item only for logged-on users

Question

I'm new to ASP.NET MVC and am using version 1.0 of the framework. I have a site.master page with the following hard-coded menu

<div id="menucontainer">
    <ul id="menu">              
    <li><%= Html.ActionLink("Home", "Index", "Home")%></li>
    <li><%= Html.ActionLink("Drivers", "List/?category=Drivers", "Product")%></li>
    <li><%= Html.ActionLink("Irons", "List/?category=Irons", "Product") %></li>
    <li><%= Html.ActionLink("Wedges", "List/?category=Wedges", "Product") %></li>
    <li><%= Html.ActionLink("Putters", "List/?category=Putters", "Product") %></li> 
    </ul>  
 </div>

I want to show an extra item on the menu only if users are logged on. Something like "View My Listings". I have no problem doing this in a dirty hacky way so I have tried

<% if (User.Identity.IsAuthenticated) ...

but User is not valid in this context. My question is how to show an extra menu item only if users are logged on?

Answer 1

For MVC 4+ We do like this:

@if(Context.User.Identity.IsAuthenticated) {
     <li> @Html.ActionLink(... 
   }

Answer 2

I also just discovered that I could use

<% if (Request.IsAuthenticated) { %>
  <li><%= Html.ActionLink("View my Listings", "MyListings", "List")%>
<% } %>
