Next, I need help .... I have a class that reads, converts and sends two parameters to the main report (StartDate and EndDate). In the main report, I do not need to define any queries, since I have four sub reports with querys of my own. Each subreport has the same two parameters (StartDate and EndDate) sent by the main report. It turns out that the thing does not work and it seems to me that the parameter values are not coming up in the sub reports. I've already made sure to set / send the main parameters to itself and to all sub-reports. When I use literal values in querys the thing goes that it's a beauty, but when I try to send the parameters to the thing I'm stalking / giving error. Has anyone gone through this or can you help me?
