User control with if/else statment? : So.. I want to include an ascx file with navigator bar. There are two versions, one shows up when user is not logged in and one is for logged user.

        <div class="navigator">
                 
        <uc1:nav runat="server" ID="nav" />
              
        </div>


This is how I can link one of the nav... but I have no idea how to make this path into if/else statment 

Tried to do some things inside of <% %> but.... without any success.

Could anyone help me?
