  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
