Hi Team,
I have a page with Radgrid, LoadingPanel, and some ASP Panels on it.
My grid has more than 1000 items on it and I don't want paging also. So I have to show all items on single page only.
The number of items on page may vary, can be greater or less than 1000.
When I select all items on page and click Add button, it throws a server error.

JavaScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

When I test the same scenario on a published link, I get different error message.
A script on this page is causing Internet explorer to run slowly. If it continues to run, your computer might become unresponsive

Here is my MasterPage:

Hi Lokesh,

To prevent such warning message, you must have less number of rows in the page. To optimize the performance consider reducing the number of visible column as much as possible (either hiding some of the columns or removing them completely and extracting their values on the client using key values), enable paging or virtual scrolling for grid, and disable the client-side features which you do not intend to use.

Additional hints about how to speed up the performance of our web grid can be found here:

In my case it's an ISS issue, If your running your project in IIS express in VS 2013 like mine try changing this

To This, change (../) to tilde(~/)
