Page breaking

rbuser

Is it possible to force RB to start a new page if there is not enough room
left on the page to print all stretchable fields of a record, i.e. the
equivalent of a Group's keep together property.

My report template comprises of TppDBMemo fields seperated by vertical
lines, all of which stretch with parent. If a page break occurs in the
middle of a memo, the rest is printed on the next page but without the
lines.

Check out the grouping option. I believe you can specify "keep group together" If the memo cannot be printed entirely on the page it will eject to the next.

Question:

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

2 of the best solutions follow:

Solution 1:

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;


Solution 2:

1. Place a subreport at the point where you might want a page break.

2. Remove its summary band and reduce the height of its detail and
title bands to zero.

By programmatically setting the title band's NewPage property you can
conditionally force a page break. Note that everything after the
subreport that is in the same band with it will need to
ShiftRelativeTo the subreport.

Thanks for the info but it does seem a bit of a fiddle for what is a simple
objective. Can I suggest the inclusion of a "Keep Together" or "Start New
Page If Row Doesn't Fit" property for the DetailBand in a future release.

Cheers,

James,

Try placing everything in the Detailband inside a Region. Then you can set
the Region.KeepTogether property to true so the detail fields will stay
together if the page breaks.
