DX：神奇的LayoutControl.BestFit()

自动生成LayoutControl后，界面总是不对：

在LayoutControl中找到一个BestFit()方法，调用后神奇的结果出现了，这不正是我想要的吗？

测试代码：

public partial class TEST2 : Form

{

    public TEST2()

    {

        InitializeComponent();

    }

    private void TEST2_Load(object sender, EventArgs e)

    {

        layoutControl1.Root.Clear();

        LayoutControlItem billDateItem = new LayoutControlItem();

        billDateItem.Control = new TextEdit();

        billDateItem.Text = "日期";

        billDateItem.AppearanceItemCaption.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;

        layoutControl1.Root.AddItem(billDateItem);

        LayoutControlItem billCodeItem = new LayoutControlItem();

        billCodeItem.Control = new TextEdit();

        billCodeItem.Text = "单号";

        billCodeItem.AppearanceItemCaption.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;

        layoutControl1.Root.AddItem(billCodeItem, billDateItem, InsertType.Right);

        LayoutControlItem billStateItem = new LayoutControlItem();

        billStateItem.Control = new TextEdit();

        billStateItem.Text = "状态";

        billStateItem.AppearanceItemCaption.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;

        layoutControl1.Root.AddItem(billStateItem, billDateItem, InsertType.Right);

        LayoutControlItem iotypeItem = new LayoutControlItem();

        iotypeItem.Control = new TextEdit();

        iotypeItem.Text = "出入库类型";

        iotypeItem.AppearanceItemCaption.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;

        layoutControl1.Root.AddItem(iotypeItem);

        LayoutControlItem workshopItem = new LayoutControlItem();

        workshopItem.Control = new TextEdit();

        workshopItem.Text = "生产车间";

        workshopItem.AppearanceItemCaption.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;

        layoutControl1.Root.AddItem(workshopItem, iotypeItem, InsertType.Right);

        LayoutControlItem warehouseItem = new LayoutControlItem();

        warehouseItem.Control = new TextEdit();

        warehouseItem.Text = "仓库";

        warehouseItem.AppearanceItemCaption.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;

        layoutControl1.Root.AddItem(warehouseItem, iotypeItem, InsertType.Right);

        layoutControl1.BestFit();

    }

}
