Combining reports with SetReportProperty

rbuser

Hi, I'm using D2007 Win 32/ ReportBuilder 10.06

I have a MasterReport with a SubReport on the detailband and wants to load
different reports into the SubReport runtime. I need to do it in a pbChild
style to prevent the subreports starting a new page.

I'm using this code in the master report detailband BeforePrint:

SubReport.SetReportProperty(GetMySubReport(jitPipe.recordindex));

With the MasterReport.Detailband.PrintHeight = phDynamic and
SubReport.PrintBehavior=pbChild

This works fine when the subreports fit into one page, but hangs when it
spans over to the next page (Previewer never finish calculating the next
page).
For the record: the subreport previews fine by itself, so it shold not be a
terminating problem.

Any ideas?

Rather than changing the subreport.Report while the application is running.
Prior to calling Report.Print, create a separate Subreport instance for each
report layout that you need to print. Then use Band.BeforePrint to set the
subreport.Visible property for each subreport.

(I think the other approach is prone to what you are experiencing.
Band.BeforePrint will fire when the subreport generates on the first page
and it will fire again, when it overflows. which means that you are again
setting up the subreport and it is starting over, thus infinite generation.)
