CHAPTER 5 ?– INTRODUCING SERVER CONTROLS IN ASP.NET AJAX 107
Figure 5-13. Timer control demo
Summary
This chapter introduced you to the server controls that are available to ASP.NET AJAX
programmers. It walked you through using the ScriptManager control, which is at the
heart of ASP.NET AJAX. This control takes care of managing the ASP.NET AJAX runtime as
well as associated scripts. Additionally, you looked at the UpdatePanel control, which is at
the heart of how ASP.NET AJAX enables AJAX functionality in existing ASP.NET pages
using partial-page updates.
This chapter gave you a high-level overview of the main ASP.NET AJAX server controls
and how they work. There is another group of ASP.NET AJAX server controls called the
extender controls that ship in the ASP.NET AJAX Control Toolkit. Although we didn??™t
discuss these controls here, they will be covered thoroughly in Chapters 7 and 8. In the
next chapter, you will look at some applications and samples that use this functionality,
dissecting them to understand how you can program similar applications of your own
in ASP.
