Hi team,

Waiting for your valuable reply.

Hi Harshal,

Such long JavaScript exceptions are usually thrown by the Microsoft AJAX Framework and that indicates that there are errors/exceptions on the server but they are being hidden by AJAX. To find out more about the issue, turn AJAX off temporarily and test the application again. Once you do that the error from the server will be visible in the browser, see Get more descriptive errors by disabling AJAX. Once the error shows up you will have a better idea of what causes the problem and you'll be able to spot it right away.

We highly advise every developer, to make the Web application fully functional before turning AJAX on. The AJAX is only there to smoothen the process of multiple PostBacks and also increase performance, but the application must be fully functional before this is enabled.

Kind regards,
