Skipping labels.

rbuser

I know this is a reoccurring theme in this group. I have a quick question.
I have followed your skip label example and I have made one change that I
thought would work but it has not. Because our customer can load a custom
label at run time I don't know each field to set it's visible property to
false so I just set -> ppReport1.DetailBand.Visible := False;

However I still see the labels I wanted to skip.

One questions.

Will setting the detailband.visible to false do what I am
expecting........mainly suppress all the printing to the page but Rbuilder
still thinks it printed a label in that position so it moves to the next.

Thanks

Hi Paul,

Which event are you setting the DetailBand.Visible := False? You are going
to want to use the DetalBand.BeforePrint event to check a condition and set
the visible property. If you are already doing this, please send a small
example demonstrating this behavior to support@digital-metaphors.com and
I'll take a look at it.

Nico,
here is the only change I made to your skip label project.

procedure TForm1.ppDetailBand1BeforePrint(Sender: TObject);
begin
if ((((ppReport1.CurrentColumn - 1) * FTotalBandsPerColumn) +
ppReport1.DetailBand.Count) = (FSkip - 1)) then
begin
ppReport1.DetailBand.BandsPerRecord := 1;

ppDBCalc1.Visible := True;
ppDBText1.Visible := True;
ppReport1.DetailBand.Visible := True;
end
else
ppReport1.DetailBand.Visible := False;
end;

I would expect this to print one label down the page by the number of fskip
when the label number is = fskip-1.

nothing at all prints out

Am I thinking wrong?

I noted that if the detailband.visible := flase then the detail bandcount
remain's at 0 and does not increment.

Is this a bug or is this as expected.

Thanks in advance for your help

Hi Paul,

After further research, it looks as though setting the detail band's
visibility to False will not work for the Skip Labels example. The example
relies on the DetailBand.Count property to increment to work correctly yet
when you set the detail band's visibility property to False, this property
does not increment because there is no detail band present. My suggestion
would be to possibly place a TppRegion inside the Detail band with invisible
borders and ParentHeight and ParentWidth set to True and toggle the
visibility of that object rather than the entire band. If the region is not
visible, your users will not even know it is there for the most part.
