Disregarding the RTF for a moment, you'd need to save the contents of the
text fields in a TStringlist instance in the 'afterscroll' event of the dataset.
This instance can then be used to create a data loop for a sub band
(using TFPReportUserData).
The band connected to the dataset (the master band) would not print anything.
Instead, the child band will print the cell content line by line and split it
over pages.
From your drawing, it is not quite clear how you construct your columns,
if you're using columns, I'm not sure how the band will behave.

Thanks again for your suggestions. I haven't tried it yet but now I've got the
idea. Your are so optimistic but I still fear all the things which might make
troubles in a more complex report with grouping, master/detail data,
calculations, layout adjustments, HTML tags, table borders etc.
However, finally I've tried to extend/improve the original FPReport classes and
now I really have a FPReport version that supports band splitting for simple
FPReportMemos.
I was not able to implement this using inheritance - I've had to change the
original source code in the FPC folder.
Without any doubt there are still many bugs in my FPReport. But if you want a
copy, let me know! :-)
I am always open for improvements.
Please do send me your sources or a diff...
Michael.
I have just started to resume my work on FPReport. I have found some errors in
my first version and currently I am trying to add RTF support. I utilize
TRichMemo for this because I think it is sufficient for my case (I only develop
and test for Windows 10/11 at the moment). Also SVG support is wanted.
What would be an appropiate way to provide my work and partial results? As I
deal with the FPC source code, your opinion and suggestions might be
particularly meaningful.
SVG support for FPC (and consequently FPReport) is on my wishlist.
RTF support using TRichmemo is useless for FPC itself as FPReport needs to be free of LCL or other dependencies.
If at some point RTF support is added, it will be using the RTF parser included
in Free Pascal.
If you wish to submit contributions, you can supply patches using the gitlab
issue tracker.
The RTF support for FPReport can of course be submitted to the Lazarus issue
tracker or
kept on github or some other repository...
Michael.
