I use Cristal Report in my C# Application. Therefore I use the ReportDocument class.
How can I add a parameter to this ReportDocument class, which I can use in the cristal report (*.rpt file).
What do I have to do in the cristal report file (*.rpt file) to work with this parameter? Do I have to define a shared variable? Or can I work with parameter fields?
I want to use this parameter to open a subreport.
