How to inherit an user control?

[Danny Ni]

Hi,

I have an user control named GuestBook.ascx. I want to create another user
control by inheriting it. So I add a class file named GuestBookNew.vb into
the project. Inside this class file I have:

Public Class GuestBookNew
Inherits GuestBook

Then I tried to use the new control in a web form by adding
<%@ Register TagPrefix="eShop" Namespace="eShop" Assembly="eShop" %>


By the way, eShop is the VB.Net project name.

This is not working at all, I am getting "Error Creating Control" in web
form designer.

Please help.

TIA
