Two pass mode problem

rbuser

Hello, I'm using RB 14.04 enterprise and I have a problem with a report
using Two-Pass Mode.

When I preview the report at the end of the first page the detail rows
stop five rows before the end of the page but when the first page is
regenerated in the second pass, the last five rows appear.

In this situation in the second page the same five rows is reprinted.

This problem disappear if I set the single pass mode but I must use the
two-pass mode because I must know the total number of pages printed.

Thank you in advance.

Hi Massimo,

Please upgrade to RB 14.08 and retest your application. If you still
get the issue, I recommend downloading a trial of the latest version of
ReportBuilder and testing with that.

For upgrade instructions, contact info@digital-metaphors.com with your
serial number and purchasing email address.

Hi Nico and thank you for your immediate answer.

I have retested the application with RB 14.08 and 15.03 but the problem
persist.

Do you have any other suggestion ?

Thank you.

Hi Massimo,

Please create a simple example demonstrating this behavior using only RB
and Delphi components and send it to support@digital-metaphors.com in
.zip format.

Hi Nico,
unfortunately the report is very complex (seven sub-reports and a lot of
rap code) and Is very difficult to reproduce this behavior on a simple
report.

I set into the create event (in rap mode) the two pass mode on a
condition, using this command :

Report.PassSetting := psTwoPass;

Is correct ?

Since the only purpose for which I use the Two pass mode is to find the
total number of pages that will be printed, to circumvent the problem
there is the possibility of knowing how many pages will be printed and
avoid using the two-step?

Thank you.

Hi Massimo,

The code you have to set the PassSetting looks correct.

Unfortunately the only way to know how many pages will be in the report
is to have a two pass report.

Hi Nico,
I have found the problem that is related to the footer band.

Into the report structure the footer band was visible and into the
create method I had set footer.visible to false and then to true only in
a particular condition.

To solve the problem I have deleted the previous statement in the create
event, I have set in the footer band of the report structure the visible
parameter to false and in the beforeprint event of the footer i set the
visible to false or true.

I hope those informations will be useful to other Reportbuilder users.

Thank you for the support.

Hi Massimo,

Thanks for the information. Yes, altering the visibility of the footer
band for certain conditions could cause issues with page measurement
during the first pass of the report if it became out of sync with the
second pass (which it appears it was when using the OnCreate event).

I'm glad you got it solved.
