Summary
Incoming requests to ASP.NET trigger a series of events that begins and ends with the application. The page postback system simulates statefulness in a Web form through a combination of hidden form fields and JavaScript on the browser, while the code executing on the server works in a similar manner to a desktop application.Events are wired up to event handlers, which are the actual methods that execute when an event occurs. In the context of a page, event handlers may be wired up declaratively in the page or programmatically.If you want to get deeper into the specifics of server controls and events in ASP.NET, I highly recommend Developing Microsoft ASP.NET Server Controls and Components by Nikhil Kothari and Vandana Datye (Microsoft Press, 2002).You might also want to consider Chris Sells' Windows Forms Programming (Addison-Wesley, 2003), which is available in both C# and VB.NET versions. Although it's not an ASP.NET book, it does teach events and delegates in one of the most easily digestible methods I've seen. You also might be surprised at how much you can learn by developing a Windows application and applying that knowledge to ASP.NET.
