There are AJAX controls for webforms, so it hasn't really "broke[n] down hard"?

Drag an AJAX control on the form, and whatever is in there, that part of the page will be ajaxed.

I should have added a disclaimer that I haven't worked with web forms in many years, so my commentary is probably not the most infomred. The ajax controls always seemed a bit ugly to me.
