Supress detail band on master-detail with no detail data

collectivefriction

I have a report with one master and one detail band. In my dataset there will always be data in the master band but often the objects on detail band will be empty.

The detail band though when it is populated is quite large and as things l stand my report contains lots of empty space. PrintIfDetailEmpty is false on the Detaildata band.

Is there a way of supressing the detail band if there is no data to display?

DetailData1.Visible := False

Thanks gpi

but that makes the detaildata band invisible irrespective of whether there is data in any of the object on the band.

I am suprised that this is not the default position for FR, it would seem to make sense that if there is no data to display on a band then it is not displayed.

I'm pretty much sure that there's a good reason for this. I just can't think of any.

Use band's OnBeforePrint event to hide/show band

I'm using OnBeforePrint to print DetailData1 if it IS empty:

procedure DetailData1OnBeforePrint(Sender: TfrxComponent);
begin
  if DetailData1.RowCount = 0 then
  begin                  
   Engine.ShowBand(DetailData1);
   DetailData1.Visible := True;
   DetailData1.PrintIfDetailEmpty := True;
  end;                 
end;

begin
end.

And none of that, separately or together, seems to work. An example would be nice.

It's the opposite :

Set on the FR Designer the MasterData BAND :

PrintifDetailIsEmpty : True
