TAdvStringGrid Narrow Down Filter

Is there a way to get the column header check box to check all of the rows that are displayed when the grid is in a filtered state using narrow down filtering?  If I load 20 rows, filter it down to 5 and then check the header box, it checks 5 boxes, but not necessarily the ones that are displayed.


with AdvStringGrid1 do
  begin
      ControlLook.NoDisabledCheckRadioLook := True;
      Options := Options + [goEditing];
      ShowSelection := False;
      ColCount := 4;
      FixedCols := 1;
      FixedColWidth := 22;
      RowCount := 2;
      FixedRows := 1;
      ColWidths[1] := 14;
      ColWidths[2] := 150;
      ColWidths[3] := 600;
      AddCheckBoxColumn(1);
      AddCheckBox(1,0,false,false);
      MouseActions.CheckAllCheck := True;
  end;
