variable height components

rbuser

This is probably trivial stuff, but I want to use a section that does not
take up any space (vertical) if I do not wish (dynamically) to display it.
The only way I can find to do this is to use groups which I then make
invisible if I don't want them.

This is a lot of work and retro-fitting a group inside a page is even more
work.

How do i do this?

Hi Cedric,

Rather than toggling the visibility of a group band, you could either
use a TppRegion set to Stretch or child subreport. Then simply toggle
the visibility of that component inside the Band.BeforePrint event based
on what you would like to see.

If I use a region or a child sub report and I make it invisible it still
takes up space on the preview, it shows as a blank area.
What am I doing wrong?

This depends on the design of the report. First be sure the band has a
dynamic height (phDynamic). Second, if there are any non-stretchable
components below the empty region, they also need to be placed into a
region which is then set to ShiftRelativeTo the invisible one.
