Can anyone point me in the right direction on how to run only the parameter values that are selected from the drop down to view the report, instead of it running all of the records or how to resolve the below error. I am using a Group By, but still have 67,000 records in the drop down, but I believe it is erroring, because of it trying to run through so many records, so how can I have it run only the selected records in the dropdown?
The error I get is:
Sys.WebForms.PageRequestManagerServerErrorException:
An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
I receive this error from the Report Server. The report runs fine from Report Manager and Report Builder.
And, I already added these lines to the Report Servers web.config file:
<appSettings>
<add key="aspnet:IgnoreFormActionAttribute" value="true" />
<add key="aspnet:MaxHttpCollectionKeys" value="100000" />
</appSettings>
Any help is appreciated.
