Forcing Group Headers to Start on Odd Pages

Question: "I have a report that is printing duplexed and therefore I want to force the group headers to
start on odd pages."

Solution:

Using demo report #71 do the following:

1. Add a subreport to the GroupFooter band, just below the existing controls.
2. Set the subreport's PrintBehavior property to pbSection - do not add any controls to the subreport - leave it blank.
3. Add a Private field to the form: FPrintingSpacer: Boolean.
4. Add an event handler for the FormCreate event with the following code:

 FPrintingSpacer := False;

5. Add an event handler for the ppOrderDetailGroupFooterBand1BeforePrint event with the following code:

 if not FPrintingSpacer then
    begin
      ppSubReport1.Visible := odd(ppOrderDetail.AbsolutePageNo) and 
        not ppOrderDetailGroupFooterBand1.Overflow;
      FPrintingSpacer := ppSubReport1.Visible;
    end
  else
    FPrintingSpacer := False;

6. Run the project and view report #71.

Note that when a group is to start, it will only start on an odd page.

Caveats: We are brute-forcing this solution by causing the even numbered page to be taken up by the section style subreport. As a result, any page headers or footers you have in the main report will not appear on the even pages that are blank. To get around this, you could add identical header/footers or custom header/footers with only page numbers, or some such.
