Numbering Detail-Lines

rbuser

What's the suggested way to print the record number at the beginning of the
detail line.
I'm using a TppLabel and fill it with ppDetailBand2.count.

Hi Norbert,

Try placing a DBCalc component in the detail band and set its calculations
to Count(*).

In my case Count(*) gives me always zero.
I've done it with
object rvLfdNr: TppVariable
CalcType = veDataPipelineTraversal
DataType = dtInteger
DisplayFormat = '"("0")"'
OnCalc = rvLfdNrCalc
ResetComponent = ppGroup1
ResetType = veGroupStart
CalcDataPipelineName = 'rpE'
end
and
procedure TrbDr.rvLfdNrCalc(Sender: TObject; var Value: Variant);
begin
rvLfdNr.Value := rvLfdNr.Value + 1;
end;

rvLfdNr.Value instead of Value was necessary to realize the DisplayFormat.

Hi Norbert,

Glad you got it working. A DBCalc with the calculation Count(*) should not
ever keep giving 0 if it properly connected to a dataset. Be sure it was
connected to the dataset the report is connected to.

Surprise, surprise: I've added a new TppDBCalc to the detailband, typed *
for datafield, set the resetgroup and - it works.
Don't know whats wrong in the first try. I'd only choosen a datafield
instead of typing *. But this works now also.
Thank you.
