问题 I am little confused about Update Panel usage and usage of Jquery:Ajax() method. Do both of them are used for Partial Post backs.. Which is the best approach to fallow?

The browser then replaces the contents of the update panel with the new html. jQuery's AJAX method allows you to make any request to any page and handle the response data

Any other major differences? ...and CallBack (without ViewState) vs WebMethod.
