Hello Kishor,

Please check the IIS settings for the process:

1. If the used connection strings allow connection to the database;
2. If there are proper read/write privileges for the process to access the cache, if it is configured in the application;
3. If the authorization rules allow access to the viewer's handler - Telerik.ReportViewer.axd;

If it is an emergency, please use our support ticketing system to send us a demo project that reproduces the problem. Using the support ticketing system guarantees you an answer by Telerik representative in a timely manner.

Regards,

hello

 I observe that the above error occours only if there are more records in report

because some of the reports work properly having 20-25 rows of records

is there any restriction on size / number of records in reports.
please guide me.

or please explain me the other setting that are required tio set in IIS.

thanks
Kishor

Hello Kishor,

The report is a document processed and render on the server with the assigned to it data. In general there are no limitations for the used data as long as the machine has enough memory and CPU to handle the document generation - Performance Considerations.

In your case, my recommendation is to use Fiddler and check the Inspectors - Response - Raw tab to check the actual response. Then check the server's Event Viewer for any error logs. The actual exception's stack trace will be helpful to identify the problem and troubleshoot it.
Test also the suggestions from my previous post and let us know the result of each and the logged exceptions.
