Creating reports and dashboards | Stimulsoft community forum

Hi,
I've a report with two data source. The second data source has as parameter a value of the first data source (attached Stim1.png).
In the preview I' don't have a problem, the render is ok.
When I call the report by the code (.NET), where I value only the parameter of the first data source, and after I call the method .Render(), the second data source is empty.
Do I need to call another method?
Thanks

Hello, Marco.

There could be different reasons.
What type of data source do you use?
Did you try to change the order of the data sources?
Do you get any message in the Report Checker?
Could you send us a sample project that will help us to reproduce the issue?
We will be able to answer your question after debugging it.

Thank you.
