[2005] ASP.Net and reloading contents of a Listbox?

Hey guys, before I go off and code this with Ajax, I was just wondering if ASP.Net already supported this natively.

Basically, 3 select boxes (if you prefer it in html :p) / Drop Down Boxes (or if you prefer asp :p), the first one controls the contents of the second one based off what you choose, and the second one controls the contents of the third.

Is there a way to do this in ASP easily? Or do I need to stick with Ajax?

Thanks in advance. :)


Edit: Lol! Microsoft just released Ajax for ASP.Net and it has a control for doing this. :)

ASP.NET can do that too...
