Using Subreport in Crystal Report and ASP.NET C# -

my main report , subreport similar each other, using same parameters , formula difference order in derails section. when load subreport in report , run it, asp.net keeps on asking enter values parameters used.

i think need have code loads subreport.

 protected void page_load(object sender, eventargs e)     {                 report.load(server.mappath("monthlysalesreportp.rpt"));           report.setdatabaselogon           ("sa", "pw", @"databasename, "servername");            crystalreportviewer1.reportsource = report;         crystalreportviewer1.reuseparametervaluesonrefresh = true;         crystalreportviewer1.databind();         crystalreportviewer1.separatepages = false;            report.setparametervalue(0, monthlastyear);         report.setparametervalue(1, monthcurrent);         report.setparametervalue(2, monthprevious);         report.setparametervalue(3, rp);         report.setparametervalue(4, loc);         report.setparametervalue(5, cms);         report.setparametervalue(6, yearcurrent);         report.setparametervalue(7, yearprevious);         report.setparametervalue(8, yearlastyear);         report.setparametervalue(9, fullname);   } 

should include code needed read subreport?

i see suggestion

report.setdatasource(dtproductview); report.subreports[0].setdatasource(dsheader.tables[0]); report.subreports[1].setdatasource(dsfooter.tables[0]); 

but not have datatable or dataset, directly stored procedure

1. have tried linking parameters of subreport main report?

   (change subreport links in subreport context menu)

2. you can try, also:

   report.subreports[0].setparametervalue(0, monthlastyear);
