How to hide my menu for non authenticated users?

Question

I have authenticated users to log on my system using this code:

FormsAuthentication.SetAuthCookie(user, false);

I want to hide my system menu for non authenticated users. Something like this:

<% if(???) {%>
   <ul id="menu>
      ...
   </ul>
<% } %>

How can I do this?

Thank you.

Answer 1

if (Request.IsAuthenticated)

(This is how it's done in the default ASP.NET MVC template)

Answer 2

if (Request.IsAuthenticated)

There's an example of this in the login user control of the basic mvc project.

if you want roles then

if (HttpContext.Current.User.IsInRole("myrole"))

Answer 3

I think you want to use:

<% if(this.User.Identity.IsAuthenticated) { %>
<% } %>
