如何讓tcxGrid左邊顯示序號

第一步：

設置cxgrid的屬性， OptionsView.Indicator = True

第二步：

寫OnCustomDrawIndicatorCell方法

procedure TForm1.cxGrid1DBTableView1CustomDrawIndicatorCell(Sender: TcxGridTableView; ACanvas: TcxCanvas; AViewInfo: TcxCustomGridIndicatorItemViewInfo; var ADone: Boolean);
var
  FValue: string;
  FBounds: TRect;
begin
  if (AViewInfo is TcxGridIndicatorRowItemViewInfo) then
  begin
    FValue := IntToStr(TcxGridIndicatorRowItemViewInfo(AViewInfo).GridRecord.Index + 1);
    FBounds := AViewInfo.Bounds;
    ACanvas.FillRect(FBounds);
    ACanvas.DrawComplexFrame(FBounds, clBtnHighlight, clBtnShadow, [bBottom, bLeft, bRight], 1);
    InflateRect(FBounds, -1, -1);
    ACanvas.Font.Color := clBlack;
    ACanvas.Brush.Style := bsClear;
    ACanvas.DrawText(FValue, FBounds, cxAlignCenter or cxAlignTop);
    ADone := True;
  end;
end;
