Hide Band if no visible lines in subreport

rbuser

Hello all
I would like to know how its possible to hide the detail band in the main
report if there is no visible lines in the subreport (I'm hiding the lines
at runtime).

thanks in advance

You need to use the main report's DetailBand.BeforePrint event to set the
DetailBand.Visible property. For a master/detail report you can check the
detail datapipeline to determine whether there are any related records for
the current master:

if myDetailPipeline.Bof and myDetailPipeline.Eof then
myReport.DetailBand.Visible := False // no detail records
else
myReport.DetailBand.Visible := True

The problem is that there are records in the detail pipeline but im hiding
it because it does not meet the criteria to be shown and i need it in the
pipeline because of the calculations

I think you still need to use the main report's DetailBand.BeforePrint event
to set the DetailBand.Visible property. Perhaps you can create a summary
query to perform some of the calculations.
