ASP.NET by Example

Chapter 9. Using ASP.NET User Controls

One of the greatest promises of ASP.NET is smaller, easier-to-manage code. One of the ways Microsoft delivers on this promise is by providing Web developers the ability to create user controls in order to encapsulate functionality and facilitate reuse. Previously enjoyed only by Visual Basic, Java, and other GUI developers, the ability to create these user controls finally brings object-oriented concepts to Web-based GUI development. The purpose of this chapter is to give you an overview of user controls and get you started using them in your ASP.NET applications.

In this chapter you will

• Learn how ASP.NET user controls differ from include files in previous versions of ASP

• Learn how to create ASP.NET user controls to encapsulate logic and reuse code

• Learn how to expose properties, methods , and events from ASP.NET user controls
