I have series of nested groups, for some of them, I would like to be able to print the group header in a whole page, then print all the detail items in the next page and continue the report.
You might try either placing a Section Style subreport inside the group header with the header information inside the subreport. If this does not work, you can try using the Band.OutOfSpace property to break a page. See the article below for more ways to break a page.
--------------------------------------------- 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
>except that it added a blank page before the header.
I was afraid of that . Yes, this is the normal behavior. Section style subreports work best if they are placed in the detail band. You might try keeping the group header objects inside the group header band, then placing a section style subreport inside the detail band holding all the detail information. If this does not give you the correct results, you may have to look at some of the other options for forcing a page break.
I reposted the question on a new thread, sorry about that, I was so messy that I didn't realize basically I asked the same thing again.
If I simply drag the lower band delimiter, the one that says "^Group Header[0] : MyGroup", just to make it big enough to cover a letter and/or A4 page ... guess what ? That does the job. Now, since it look so simple, I'm afraid it could lead to some weird behavior that I'm not preventing now. Any comments on this ?
This was actually the initial way I got this type of report working. I later decided that it looked a little too messy in the designer to recommend this route. This method should work for your needs if you can stand having a band sized that big in your design .

Nico :
The trick with the section subreport seemed to work great, except that it
added a blank page before the header.
Is this an expected behavior ?
Also, respecting blank page I have to add, my report looks like :
MainReport (this contains a subreport)
->SubRep1 (the subreport in main report contains all these)
->SubRep2
->SubRep3
->SubRep7
Subreports are Section style.
In this layout I always get two blank pages before the report started, is
this "normal" ?

subreports work best if they are placed in the detail band. You might try
keeping the group header objects inside the group header band, then placing
a section style subreport inside the detail band holding all the detail
information. If this does not give you the correct results, you may have to
