Question

Answer 1

This works for me. I can include my menu on any page I want:

<div ID="menuContent" runat="server">
    <!-- #Include virtual="/menu.aspx" -->
</div>   

In my menu.aspx file I have raw html and some C# codeblocks and ASP will resolve those after inserting the content into the page. Great huh?
