Solution 1

1.Your AddToCart class (from your code behind) is not visible in your ASP page because is part of a namespace that is different then the application default one.

2.The solution is to specify also the class namespace (PayPalDemo.AddToCart) like bellow:

ASP.NET

<%@ Page Language="C#" AutoEventWireup="true" Inherits="PayPalDemo.AddToCart" Codebehind="AddToCart.aspx.cs" %>

Torakami 23-Sep-14 2:27am

not exactly as same , but adding namespaces for each classes ..your namespace concept helped me

I am glad that I could help you, so it will be nice from you to accept my solution!

PS: For any solution the idea for solving the problem is the most important, because I do not have your code to can test it.
