Any Limits on the number of subreports on a Report

rbuser

Hi,

-Is there a limit on the number of subreports per report? I want to make a
report consisting of 4 pbsection style subreports. Each pbsectionreport will
contain a number of pbchild subreports. I would need +/- 150 subreports to
get this done. Is this a good idea?
- Each pbchildreport will have to print data from the same pipeline but only
a range from the total of rows. In each pbchildreport.OnPrint event i will
activate a filter (See below) and it will be only printed when it contains
filtered data. Is it ok to activate a filter on the
pbchildreport.DataPipeline.DataSet in the pbchild subreport.OnPrint ?

procedure TForm3.ppSubReport1Print(Sender: TObject);
begin
Details.DisableControls;
try
Details.Filtered := False;
Details.OnFilterRecord := DetailsFilter11Record;
Details.Filtered := True;
finally
Details.EnableControls;
end;

ppSubReport1.Visible := not(Details.IsEmpty);
end;

Hi Filip,

Although we have never tested a report with 150 subreports, is should be
possible. If this gets too dificult to manage, you may consider saving
these subreports as templates and creating them dynamically as you need them
in your main report.

Also, firing the code below in the Subreport.OnPrint event may not be early
enough to set that subreport's visibility to False. You may need to do this
in the Band.BeforePrint event.
