Print Empty rows if dataset is empty

  Make bands as you described and be sure to check the property Print if Detail Empty in your master data band
  
  You may want to look at other psots on child fillers if you desire to reserve or fill up the empty space in your report
  Be sure you have print on first and last page checked for your header and footer
  Hope that helps

  In the script, in the OnBeforePrintEvent of any of the bands (probably the header, maybe even of the page, if it's a simple report), check for the number of records of your dataset, and if = 0, set the masterdata1.rowcount property to 3 (the number you said you want its height to be).
  something like:
  

  Page1.OnBeforePrintEvent();
  begin
  if MyDataset.recordcount = 0 then
    masterdata1.rowcount := 3
  else
    masterdata1.rowcount := 0;
  end;
  

  
  The rowcount set to anything other than 0 means you are forcing it to be printed X number of times, regardless of the dataset (even if it doesn't have one).
  The Header and Footer should behave as you expect with this.
  I hope it helps

  the rowcound property has no effect when the band is connected to a dataset., it only controls howmany times the band outputs its objects to the output page. if the band is connected to a dataset the dataset controls the output.

  Well, in that case...
  

  Page1.OnBeforePrintEvent();
  begin
  if MyDataset.recordcount = 0 then
     begin
       masterdata1.Dataset := nil; 
       masterdata1.rowcount := 3;
     end
  else begin
       masterdata1.Dataset := MyDataset;
       masterdata1.rowcount := 0;
       end;
  end;
  

  
  (It's getting a little dodgy at this point, if this doesn't work, try another way)

  that would result in the first record of the master data printing n times unless you write code to control the dataset movement.
  if your bands and record spacing is always the same height(not stretching )
  instead of using framesof memos add an overlay band and use lines.
  tip on overlays they are realy underlays, set the designer page to large height in design mode
  add your overlay band below all others after designing

  Hi All
  
  Thanks for the suggestions. I found this forum topic which gave me my final solution [topic="5791"]Repeating the MasterData for n-times[/topic].
  Below is my final code. I would be keen to know, if there is a better way of doing this.
  
  var
  bPrintedLastTop3International : Boolean;
  bPrintedLastTop3National : Boolean;
  dsTop3National: TfrxDataSet;
  dsTop3International: TfrxDataSet;
  
  ...
  
  procedure MasterData21OnBeforePrint(Sender: TfrxComponent);
  begin
  if (Engine.FinalPass) then
  if (dsTop3National.RecordCount>0)
  and (dsTop3National.recno <= dsTop3National.recordcount)
  and (not bPrintedLastTop3National) then
  begin
  if (dsTop3National.recno = dsTop3National.recordcount) then
  bPrintedLastTop3National := True;
  Memo24.Text := dsTop3National.Value;
  dsTop3National.Next;
  end
  else
  Memo24.Text := '';
  end;
  
  procedure MasterData22OnBeforePrint(Sender: TfrxComponent);
  begin
  if (Engine.FinalPass) then
  if (dsTop3International.RecordCount>0)
  and (dsTop3International.recno <= dsTop3International.recordcount)
  and (not bPrintedLastTop3International) then
  begin
  if (dsTop3National.recno = dsTop3National.recordcount) then
  bPrintedLastTop3International := True;
  Memo27.Text := dsTop3International.Value;
  dsTop3International.Next;
  end
  else
  Memo27.Text := '';
  end;
  
  //Main script begin ... end
  begin
  dsTop3National := Report.GetDataset('fdtsHL_Top3National');
  dsTop3International := Report.GetDataset('fdtsHL_Top3International');
  if (Engine.FinalPass) then
  begin
  dsTop3National.First;
  dsTop3International.First;
  bPrintedLastTop3International := False;
  bPrintedLastTop3National := False;
  end;
  end.
  
  Regards,
  Regan

  Hi
  
  Sorry, forget to add the RowCount property of the MasterBands were set to 3.
