Section subreport

rbuser

Hi,

I'm using Delphi7 and RB 7.01 now. I have a report structure like this: In
the details from the Main Report(No DataPipeline), there are 4 SECTION style
supreports: Subreport1(DataPipeline1), Subreport2(No DataPipeline),
Subreport3(DataPipeline2), Subreport4(DataPipeline3). If I hide Subreport3
and Subreport4, the report engine does print the report correctly
(MainReport, Subreport1 and Subreport2). The problem I have is that if I
hide Subreport1 and Subreport2, then the report engine prints like:

MainReport, BLANK PAGE, Subreport3 and Subreport4

if I ask to print them all (all subreports are visible), it does print
MainReport, Subreport1, Subreport2, Subreport3 and Subreport4, Obviously I
don't have any code to ask to print a blank page. so where is this blank
page comes from?

Thanks

William

As a test try creating a new report that contains only main, subreport3 and
subreport4. Does that print correctly?

Is there anything in subreport3 that would cause a page break - a start new
page group perhaps or a title band.


Try setting the Visibility prior to calling Report.Print.

Hi, Nard

As I said, I don't have anything would cause a page break. otherwise
printing all of them together would have problem, which I don't have, what I
did is wrote the RAP code in the Report.BeforePrint:

if Condition then
begin
Subreport1.Visible := True;
Subreport2.Visible := True;
Subreport3.Visible := False;
Subreport4.Visible := False;
end
else
begin
Subreport1.Visible := False;
Subreport2.Visible := False;
Subreport3.Visible := True;
Subreport4.Visible := True;
end;

NOW, I found where the problem is, Since every report has a footer with a
PageSetDesc system variable(Sorry, not metion it in my previous message), In
order to make the report engine won't print a blank page, I have to make the
footer of Main report to INVISIBLE!.

This is not good, and I think this is a BUG! Please let me if there is a
workaround.

Try modeling the report a slightly different way.

Create a main report that has only a detail band - no header or footer.

Use a section style subreport to print the first page. (this will be what is
now the first page).
Then print the remaining section subreports (1, 2, 3, 4).

Hi, Nard

It worked!!!, Thanks a lot. BTW, Why could it happen?

The recommended method of modeling the output you require is to use the
approach that I suggested.

If the main report has a footer and contains section, there may be a
tendency for the generating process to get confused on what
report/childreport is in control of a page. In other words the concept of
page is getting confused. By using a main report with only a detail band,
the main report will act as a driver and will not have any pages to
produced.
