CodeBehind for .ascx file isn't working

Beginning asp.net 1.1 with vb.net 2003 -- Chapter 12 summary.

I'm trying to do step 3 in the summary of chapter 12.

my difficulty is that it says you can write the codeBehind file just as we did for all the other pages. However I think this is a mistake in that this is not a page but a control. I have imported all the namespaces for the objects referenced in the NavBar UserControl. However I'm struggling with the reference to the Session variable, I think it need the System.Web.UI.Page namespace imported, but then I get some ambiguous message because I'm importing the System.Web.UI.Control namespace too.

Has anyone successfully done step 3? If so how?

Thanks

got it.

navbar.ascx

Code:

<%@ Control Inherits="Wrox.navBarCodeBehind" Src="navBar.ascx.vb" %>
.....

the book says exactly like the other examples here we need a directive to the "Control" class not the "Page" class like all previous examples.

navbar.ascx.vb

Code:

Imports System
Imports System.DateTime
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.Web.UI.UserControl

Namespace Wrox

    Public Class navBarCodeBehind : Inherits UserControl

Obviously we need to import all namespaces which are referenced in the code but in addition we need to import the System.Web.UI.UserControl namespace and then inherit all characterisitcs from the class "UserControl" into our newly created navBarCodeBehind class -- not quite exactly how we did all previous snippets.

For anyone else going through Beginning ASP.Net 1.1 with vb.net 2003.
