Gerke Geurts has also
AJAX lately, with some pointers to resources and a company here in the
Netherlands called BackBase with some
excellent demos on how AJAX should work. They’ve build their own framework on
top of Java.
I just saw some more
links on Robin Curry’s website with some links on how to get functionality
like Google Suggest in ASP.NET 2.0 but also some example for the current
versions. Have fun!
