NoData Event...

rbuser

I like to hide the detail band completly when the report does not contain
any data. Unfortunatly the row is being printed before the event is
triggered. Can I somehow detect if there is data in the "BeforePrint" event
or manage to do this in another way?

Configure the NoDataBehaviors property of the report to BlankPage.

If you want to check for records in the BeforePrint event of the detail band
then you can do this:

procedure TForm1.ppDetailBand1BeforePrint(Sender: TObject);
begin
if ppReport1.Datapipeline.EOF then
ppDetailband1.Visible := False
else
ppDetailband1.Visible := True;
end;

And you'll want to also check to make sure that the RecordNo property of the
data pipeline is equal to zero.

Hi Jim,

I solved that problem a bit before you posted your solution. However,
slightly different. Your solution does not work as the datapipeline does not
contain any meaningful data during the "BeforePrint" event (trying to
opening this pipeline causes an error that there is no query to be executed
in my DADE plugin). What I do now instead is, I assign the OnStartPage event
just before I do the print, determine there if the detail band should be
visible (using the same method you have suggested in your solution) and
unassign the event handler by setting it to nil.

Seems to work fine
