making own asp.net mvc2 web app first time. i've been using rails 3 years , consider myself pretty proficient framework. switching over, i've been reading pdfs , far impressed @ asp.net has offer. web app have ton of javascript in , i'm going use jquery. i've read nerddinner's pdfs on ajax still don't seem give me want. example, in rails, can make ajax call controller renders js partial, , in partial, able access different variables update view. what's asp.net equivalent of that? there tutorials can better me understand how asp.net handles ajax?

the js partial in rails nice. don't know there's equivalent in asp.net mvc. 1 thing serialize object json. in callback, can use properties of json object dynamically update html javascript. take approach. hope helps.

another option return normal aspx view. in case, response html , can drop div. aspx view contain script tags modify dom on $(document).ready()
