The following is my code and it is working with only one report.
rptbill = New CrystalReport1
rptexp = New ExpensesReport
rptmain = New MAINREPORT
rptbill.SetDataSource(dtincom)
rptexp.SetDataSource(dtexp)
frmCrystalReport.CrystalReportViewer1.ReportSource = rptmain
What I want is that my rptmain shows the field of my submenus rptbill and rptexp. I don't know how to get this to work.
