I use the Reportingservice V5 to print a DevExpress report. This gives me the following error:

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

I use the same report to create a pdf and that works fine. I also use the same report within the (Windows) gui and that also works fine. So why would the report try to show a dialog form when I try to print it using the Reportingservice? Any help would be appreciated.

 

Using TW 2022.1 and Reportingservice 5

A possible reason for the popup to show is a mandatory report parameter without a value.
Could that be the case?

I don't think so. I checked all of them and the point is that I can create a pdf of that same report and I can also mail that pdf. That all seems to work fine. I use only 1 report parameter. I also checked the params in the get_reports procedure.

I suspect it is something similar to a pop-up generated because of incorrect margins or alike. Is that possible? Is it possible to suppress these kind of dialogs in DevExpress?

This has been fixed in the 5.04 release of the Reporting Service.
