Hi:
I want to write a report where even lines are written with no
background and odd lines with a light gray background.
The idea is an memo (MemoBackground) in the background of the
masterData Band that is gray and I set visible or invisible,
according with the line.
I have created a report variable "LineCounter"
In the ColumnHeader band (the report has two columns) I have a Script
Begin
LineCounter:=0;
end;
In the GorupHeader header I have this script
Begin
LineCounter:=0;
end;
In the masterData band Script:
begin
LineCounter:=LineCounter+1;
MemoBackground.visible:=(LineCounter mod 2 = 0);
end
Probably the easiest way of doing what you want is using an empty memo
object sized to the extent you want for the background row, any other
field on the band should be 'above' the background memo (you can just
select the background memo and press the 'send to bottom' tool
button), any field on the band should be transparent color. Then edit
the background memo and use this script:
if [LINE#] mod 2 = 0 then
FillColor := clGray
else
FillColor := clWhite;
As written and because the variable Line# starts at 1, the first line
will be white.
You can apply this method to any existing report as it doesn't require
modifying the source code of your application.
Regards.

Ok I'll try
Nevertheless, that doesn't answer my question: How to use
"not-predefined" variables. How can I access to the variable lineCounter?
