The company I work for generates multiple PDF reports everyday on a schedule. We loop through a list that we generate reports for. The reports have multiple sub reports that have datasources that connect to our databases. The sub reports have sub reports as well. We have run into an issue that we have been wrestling with and need some assistance.
Every now and then a report is generated, without throwing errors, that is mostly blank. All it has on it is some text, a logo and a page number; none of which are sub reports. We have error handling all around the code in which does the actual rendering, yet we don't see an exception being thrown. We also check to see if there isn't data for the report before and if there isn't we don't ask the Telerik Reporting library to render anything.
I've attached three images, the first is "blank" report and the second that is populated report. The blank report was generated through our automated process along with other reports. The populated report is one that I generated using the same code but manually outside of the scheduled time in which we "batch" generate reports. These would be considered the same report, because the same parameters were used in the query for the same database.
The third image is the report designer view of the same report -- the top most report.
Thank you for any help you can give us.
