Dear asp.net gurus:

I have a asp.net web page where I need user enter product serial number, and I need to validate the user's entry; if the serial number already exists in SQL server database, then asp.net validator will display error message like 'serial number has been used'. I do not want to do this check on the clientvalidation. I knew that can be done by creating a javascript calling a asp.net static page method and then return the isvalid value to validator. The isvalid value is exchange by using JSON serialization?

I just wonder if anybody can give me some example and source code  to show me how to implement the way I want it to be.

Please do not just copy and paste some links to me, please give me some explananation and then I can know how to integrate with my project.

Thanks in advance.

Shawn
