  You can add watermark in the TfrxReport.OnEndDoc

  procedure TForm1.frxReport1EndDoc(Sender: TObject);
  var p: TfrxReportPage;
  m: TfrxMemoView;
  i: integer;
  begin
  frxReport1.Preview.Lock;
  for i := 0 to frxReport1.PreviewPages.Count - 1 do
  begin
  p:=TfrxReportPage(frxReport1.PreviewPages.Page[i]);
  m:=TfrxMemoView.Create(p);
  m.CreateUniqueName;
  m.SetBounds(0, 0, (p.PaperWidth - p.RightMargin - p.LeftMargin) * fr01cm, (p.PaperHeight - p.TopMargin - p.BottomMargin) * fr01cm);
  m.Text := 'Demo';
  m.Rotation := 45;
  m.Font.Size := 128;
  m.VAlign := vaCenter;
  m.HAlign := haCenter;
  frxReport1.PreviewPages.ModifyPage(i,p);
  end;
  frxReport1.Preview.UnLock;
  end;
  

  
  or before page's printing in the TfrxReport.OnPrintPage
  

  procedure TForm1.frxReport1PrintPage(Page: TfrxReportPage;
  CopyNo: Integer);
  var m: TfrxMemoView;
  begin
  m:=TfrxMemoView.Create(page);
  m.CreateUniqueName;
  m.SetBounds(0, 0, (page.PaperWidth - page.RightMargin - page.LeftMargin) * fr01cm, (page.PaperHeight - page.TopMargin - page.BottomMargin) * fr01cm);
  m.Text := 'Demo';
  m.Rotation := 45;
  m.Font.Size := 128;
  m.VAlign := vaCenter;
  m.HAlign := haCenter;
  end;

  For me this only works when commenting out these lines:

  frxReportInternal.Preview.Lock;

  frxReportInternal.Preview.UnLock;

  Otherwise it crashes in the .Lock line.

  This is FastReports 6.x Embarcadero edition in 10.4.2. The report is on a data module but preview works as expected when these lines are commented out.

  Any clue why this crashes with an access violation?

  Exception of class $C0000005 with message 'access violation at 0x00b3c969: read of address 0x00000000' occurred.

  And how to get the memo to the background instead of the foreground?
