Chapter 9: Web Forms UI

Overview

In Chapter 8, we built a Windows Forms UI based on our ProjectTracker business objects. But C# also supports web development through ASP.NET and the Web Forms technology. We can use our business objects to create a Web Forms interface in a similar manner to the way we built the Windows Forms interface.

Web Forms can be used to create many different user interfaces, and this chapter isn't intended to act as a tutorial on web development in ASP.NET. Instead, we'll focus on how business objects are used within a web application, including state management and data binding.

Tip  

ASP.NET is the .NET web-server component that hosts Web Forms, web services, and other server-side handlers in Internet Information Services (IIS). ASP.NET is a very broad and flexible technology. Web Forms are hosted within ASP.NET and provide us with "normal" web-development capabilities.

Before we get into the development of the Web Forms UI, we need to discuss some of the basic concepts around the use of business objects in web development.
