In working in the Telerik Report Designer, I am passing a field from the main report datasource to a parameter in the subreport. I have verified that the field in the main report is not null or empty by displaying it on the report, showing a value. But in the subreport it is getting passed as null for some reason (I know it is null and not empty because if I set Allow Nulls to false for the parameter it errors), and displaying the parameter on the subreport shows nothing.
I have searched this issue and all I can find is how to work with parameters in C# or VB.Net code, but I am not at that step yet and am just wanting to preview the report within the standalone designer. I can get the main report to show the data it should, but the subreport is always blank due to the null parameter.
