我试图添加一个标签，按钮，编辑和按钮到一个gridPanelLayout。我不知道如果sizestyle自动将是最好的或不想测试它。我在运行时创建组件。因此，我尝试为每个组件集添加一个新行。但是我不知道如何将SizeStyle的属性设置为auto。我目前有GridpanelLayout1.RowCollection[i].SizeStyle := TsizeStyle.auto，但它给出了错误，TSizeStyle是未声明的。

//add to grid
      gridpanelLayout1.BeginUpdate;

      if i <> 0 then
      begin
      GridpanelLayout1.rowcollection.Add;
      GridpanelLayout1.RowCollection[i].SizeStyle := TsizeStyle.auto
      end;

      GridpanelLayout1.ControlCollection.Add;
      GridpanelLayout1.ControlCollection[i].Column := 0;
      GridpanelLayout1.controlCollection[i].Row := i;
      GridpanelLayout1.ControlCollection[i].Control := (namelabel);

      GridpanelLayout1.ControlCollection.Add;
      GridpanelLayout1.ControlCollection[i].Column := 1;
      GridpanelLayout1.controlCollection[i].Row := i;
      GridpanelLayout1.ControlCollection[i].Control := (minusButton);

      GridpanelLayout1.ControlCollection.Add;
      GridpanelLayout1.ControlCollection[i].Column := 2;
      GridpanelLayout1.controlCollection[i].Row := i;
      GridpanelLayout1.ControlCollection[i].Control := (editfield);

      GridpanelLayout1.ControlCollection.Add;
      GridpanelLayout1.ControlCollection[i].Column := 3;
      GridpanelLayout1.controlCollection[i].Row := i;
      GridpanelLayout1.ControlCollection[i].Control := (Plusbutton);

      GridpanelLayout1.EndUpdate;
