showing + hiding regions --> infinite pages!!!

edited July 2002 in General
Hi!

I generate all my report builder reports at the code-level which works
very well. I now needed 3 regions to be some sort of header for 3 detail
(sub-)reports. in the BeforePrint-Event I show or hide these regions, so
I don't have to repeat headers that are the same. The problem is that
ReportBuilder has a problem with the pagebreak and somehow stops showing
the report and just shows plain blank pages! this goes on forever,
litarally. Pressing the ">>" button ends in an endless loop counting
blank pages....

any help? this is obviously a bug!

thanks,
Tom.

    See the guidlelines below for possibilities on why the report could be
    producing endless pages.

    Article: TroubleShooting: Report Prints Endless Pages
    ------------------------------------------------------

    Occasionally, we have customers state that their reports are in some
    infinite state where page after empty page prints forever.

    There are a few items to check when this occurs.

    The TppReport.AutoStop property is the first thing to check. If this is
    false when the DataPipeline property is unassigned, the endless report will
    be the result. AutoStop is automatically set to True when DataPipeline is
    set to nil, but it is possible to set it back to False. Check for instances
    in your code where you might have created this condition.

    Another thing to check is that all subreports in your report have their
    DataPipeline set. When a subreport does not have its pipeline set, you will
    sometimes see a condition where the first detail record prints and then you
    get blank pages.

    Another, non-data related cause can sometimes be your margin settings. If
    you have stretching bands that need to overflow to the next page, if your
    margins are too tight, sometimes the report engine will endlessly overflow
    to the next page trying to fit the overflow material. As a test, try setting
    DetailBand.PrintHeight to phDynamic. A dynamic height band can overflow to
    additional pages as needed.

    Still another cause might be having a statically positioned control, set to
    ReprintOnOverFlow, in the same band with a stretching control. For instance,
    if you have a memo set to stretch and in that same band, a label control set
    to ReprintOnOverFlow, then on every page after the first, the memo will
    begin to print after the label control. If the label is placed low enough
    that the memo has no room to print, the report will forever be trying to
    print the overflowing memo on the next page.

    the problem couldn't be solved with any of your guidelines... instead, David
    McNeill solved it (.public.reportbuilder.subreports): I had to set the
    StopPosition property to something like PaperHeight - MarginBottom - ..
    no it works!!
