Fresh of Code Camp in Portland, which was a blast, I’m the fill in speaker for the Portland .NET User Group meeting on Wednesday. Due to some schedule conflicts the previously scheduled speaker was unavailable and your’s truly will be filling the slot.

It’s a little short notice and I picked a session I hadn’t done before on Script Callbacks in ASP.NET 2.0 and a general overview of AJAX technology with ASP.NET. Here’s the session abstract:

Getting familiar with Client Script Callbacks in ASP.NET 2.0

by Rick Strahl

Script Callbacks in ASP.NET 2.0 are Microsoft's first step towards providing AJAX functionality in ASP.NET 2.0. AJAX provides the ability to call server code from the client side without full page postbacks using commonly available XmlHttp technology in modern browsers.  The mechanism provides the ability to have client script code call back on the ASP.NET server page and provide content to update the client page without refreshing the entire page. This session introduces the basics of the technology and then delves into how you can utilize this feature realistically in your applications. Some issues covered are determining which format to use to pass data, when to use Postbacks vs. Client Script Callbacks and how to avoid excessive complexity managing code both on the client and the server. We'll also look at ways to implement this sort of functionality in ASP.NET 1.1 and cover an overview of the underlying AJAX technology.
