Dear Experts
I used to code in ASP.net without MVC and use Update Panel, ajax toolkit for Ajax. Now a days it seems (as people tells!) this is out of date and slow comparing with JSON, jQuery etc.
Can you please suggest which way of programming (ajax update panel or JSON, jQuery or something else) best for best performance in ASP.Net with Ajax and how much code will be extra for it.
It will be helpful if can suggest some URL or ebooks to learn these quickly.
Thanks in advance for your helpful information.
