Problem with Column Traversal. (RB 12.01)

rbuser

Hi,

I've just encountered a problem. It's a new report I'm designing so I can't
say if it's new to Version 12.

I have a simple report with a subreport (pbChild) on it. The subreport has 3
column (ctTopToBottom).

What happens is, when the first column of the subreport "overflow", it makes
the report's own "overflow" indicator to be turned on, making the report
print a (potentially) blank page.

The subreport is linked to a TppDBPipeline which is linked to a
TClientDataset.

If I turn the ColumnTraversal property to ctLeftToRight, the is no problem.

Here's an exemple:

Assuming a subreport with 3 column, each printing 5 elements each.


Elements To Print | Page Printed | Blank Page

0-5 | 1 |
No
6-10 | 2 |
Yes
11-15 | 2 |
Yes
16-20 | 2 |
No
21-25 | 3 |
Yes

etc.

Is it something I'm doing wrong or is it a bug with the version?

Oh... and I did reproduce it with a test report with nothing on it except
the subreport.

Here's my setup :

ReportBuilder 12.01
Delphi 2010
WinXP
Printer : InfoPrint 1130 (Probably irrelevant as the problem is there in the
print preview on screen)

Hi Ken,

We have not seen this behavior before. If possible, please send a simple
example (perhaps using the DBDEMOS database) that demonstrates this behavior
and that I can run on my machine in .zip format to
support@digital-metaphors.com and I'll take a look at it for you.

Thanks for sending the example. I researched this. The solution is to remove
the SummaryBand. It's presence is causing the additional page. The current
implementation of the summary band always generates a new page when it is
preceded by top to bottom columns. This happens regardless of whether the
summary band has a zero height or visible false, I think this is because in
the band BeforePrint event these properties could be modified.

Improving the report engine so that the summary band can display on the same
page as the top to bottom columns is an item we have on our requested
feature list for future versions.
