Blank form at design or run time
Question:
Using QuickReports 2, I have a report with only a title band
and some QRLabels, at design or run time I can not print or
preview the form (It is blank). What is wrong?
Answer:
Most likly, QuickReport doesn't think you any Data to print or
preview. At runtime you can tell QR to print using this
techinque: On the Report's OnNeedData event, add this code:
If Form1.tag = 0 then
begin
MoreData := True;
Form1.Tag := 1;
end else
MoreData := False;
This tells the QR component that it got data, go ahead and
print. Then the component on the next time into the event to
stop - no longer needs data avoiding an infinite loop. Of
couse Form1's tag property is simple being used as a flag,
thus can be replaced by any other flaging scheme.
