  Inheritance Problems

  Apr 23, 2006 03:36 PM|LINK

  Hello and thank you for taking a moment to read this message.The practice of inheritance is something as a developer I am still struggling with a little bit. I have a page called productcatalog.aspx. It contains the following line of code.

  <%@ Page language="c#" Codebehind="productcatalog.aspx.cs" AutoEventWireup="false" Inherits="ShoppingCartCookies.WebForm1" %>

  Everytime I go to compile VS 2005 throws me the following build error:

  Error 2 Could not load type'ShoppingCartCookies.WebForm1'. C:\Documents and Settings\Jason Livengood\My Documents\Visual Studio 2005\WebSites\WebSite8\productcatalog.aspx 1 

  I was wondering if anybody could tell me where my mistake is. I would appreciate any help anybody can give. Below is my codebehind for the page.

  Thank You,

  Jason

  All that I can think of:
  1. Is the code file that you posted in the same application virtual as the aspx file?
  2. Is that code in the productcatalog.aspx.cs file? (Normally it would be named WebForm1.aspx.cs)
