My first article appeared today on DotNetJunkies.com:

I wrote about ASP.NET 2.0's new Client Callback Feature, which allows you to call server-side methods from JavaScript without the need for posting back. As an example, I built a Windows Explorer-lookalike that is all client-script driven although you navigate through the server's file system.
I'd like to thank Adam Kinney and Derrill Dabkoski for proof-reading the article and provide me with suggestions.
