Ajax Rating System

Rating Demystified: Ajax Way, Amazon
Way*
Ever wondered, how the amazon rating system works with
multiple items in the same page, here is a simple article to describe the basic
bare bones needed to create an asynchronous rating module using ASP.NET , SQL
Server and ..... AJAX

This article describes an ASP.NET web module along with some chunks of
Javascripts and ...Ajax to create a Rating System. This can be added
/customized for any table to add a rating/score module. I was
quite amazed, when i first saw the capability of rating multiple
items at amazon website without refreshing the page. That nice piece of
functionality followed me like destiny, till i needed to implement it in a
web application.

Well ! putting it in a live scenario needs much more than just
javascript. I started with a bit of frenzied hacking. To understand how
exactly it works, by scanning the javascript from online asynchronous
rating websites. That was just the beginning, on the way i learned much
more than earlier imagined. Here is the result of the
effort.
