DevExpress CxGrid ComponentPrinter如何去除打印文档中的<Filter is Empty>行？

Hey there! That <Filter is Empty> line showing up in your print preview is DevExpress's default filter status panel—it’s meant to display the grid’s current filter state. Getting rid of it is super straightforward, though.

Solution: Disable the Filter Panel in the Report Link #

You just need to toggle one property on your TcxGridReportLink (which is dxComponentPrinter1Link1 in your code) to hide this panel. Here’s how to do it:

1. Add this line of code right after your ReportPageSetUp call in the Btn_PrintClick procedure:

   dxComponentPrinter1Link1.OptionsView.ShowFilterPanel := False;
   

Modified Code Example #

Here’s what your updated Btn_PrintClick procedure will look like:

procedure TFormMain.Btn_PrintClick(Sender: TObject);
procedure ReportPageSetUp(APL : TBasedxReportLink; APaperSize : Integer; AOrientation : Integer; AFitToPage : Boolean; ATitle : String; ACenterTitle : String; ATitleFont : String; AFontStyle : TFontStyles; ATitleSize : Integer);
begin
  APL.PrinterPage.DMPaper:=APaperSize;
  case AOrientation of
    0 : APL.PrinterPage.Orientation:=dxPrnDev.poPortrait;
    1 : APL.PrinterPage.Orientation:=dxPrnDev.poLandscape;
  end;
  APL.ShrinkToPageWidth:=AFitToPage;
  APL.ReportTitle.Text:=ATitle;
  APL.PrinterPage.PageHeader.LeftTitle.Clear;
  APL.PrinterPage.PageHeader.CenterTitle.Clear;
  APL.PrinterPage.PageHeader.RightTitle.Clear;
  APL.PrinterPage.PageHeader.Font.Name:=ATitleFont;
  APL.PrinterPage.PageHeader.Font.Style:=AFontStyle;
  APL.PrinterPage.PageHeader.Font.Size:=ATitleSize;
  APL.PrinterPage.PageHeader.LeftTitle.Add('username');
  APL.PrinterPage.PageHeader.CenterTitle.Add(ACenterTitle);
  APL.PrinterPage.PageHeader.RightTitle.Add('[date printed] [time printed]');
  APL.PrinterPage.ApplyToPrintDevice;
END;
var
  AOrientation: byte;
begin
  AOrientation := Integer(True);
  ReportPageSetUp(dxComponentPrinter1Link1, DMPAPER_A4, AOrientation, true, 'Title 1' , 'Title 2', 'Times New Roman',[fsBold],10);
  // Hide the filter status panel including "<Filter is Empty>" line
  dxComponentPrinter1Link1.OptionsView.ShowFilterPanel := False;
  dxComponentPrinter1.Preview(true, dxComponentPrinter1Link1);
end;

Alternative: Set It in Design Mode #

If you don’t need to toggle this setting dynamically, you can set it directly in the IDE:

• Locate dxComponentPrinter1Link1 in your form’s component list
• Expand the OptionsView property
• Uncheck the ShowFilterPanel option

This will permanently disable the filter panel for all print jobs using this report link.
