Fixed area with overflow (2)

rbuser

Sometime ago I asked for the best way to build an end-user report with fixed
area subreports.
The solution you gave to me works (PrintBehaviour = pbFixed and
TraverseAllData=True for the overflowing subreports, ReprintOnOverFlow=True
for the remaining controls), but it seems to work only if the report layout
fits in one page.
My report actually needs two pages (the detail band layout is two pages
long). With two pages the report preview generates thousand of white (empty)
pages
I can provide an example built with your tutorial if necessary

Thanks in advance

Hi Filippo,

How are you breaking to the next page? In ReportBuilder, if the detail band
is physically larger than one page you will get the endless page effect.
You might try adding a Section Style subreport to the Footer or Summary of
your main report and adding your second page information to that. By
default the Section Style subreport will start on a new page. For
information on other options you can take to break a page, please see the
article below.

Article: Forcing a Page Break
---------------------------------------------

Question:

How can I force a page break occur based upon
a condition calculated at run-time.

Solution:

Define a Group that starts on a new page when
it breaks. Then use the Group.OnGetBreakValue
event to control the timing of the break.

1. From the Report Designer, select Report | Groups
to access the Group dialog.

2. Define a group based upon a static component,
such as a Label or Variable. Click the
Start new page checkbox. Close the dialog.

3. Using the object inspector's drop down list,
find and select the TppGroup object.

4. Create an event-handler for the Group's
OnGetBreakValue event.

5. Add code to set the break value.


procedure Form1.Group1OnGetBreakValue(Sender: TObject; var aBreakValue:
String);
begin

if condition then
aBreakValue := 'Some Value';

end;

I used a detail band with DynamicHeight.
Actually the detail band is two physical pages height.
This seems not cause and endless pages effect, unless we enable the
ReprintOnOverflow (and so on..)
Anyway I tried your suggestion:
1. I putted a section subreport in the footer band
2. put all the second page's controls in the subreport
But the second page data never gets printed
I then tried to put the subreport as the first control in the footer and
then, below it, the other controls but this cause the endless printing

Hi Filippo,

Sorry, my mistake. You cannot place a dynamically sized object inside the
page footer. Try placing the subreport in the summary band and see if you
get different results.
