        public static ComboListControl CreateComboListControl(ListLogicalView view)
        {
            var titleProperty = view.Meta.TitleProperty;
            if (titleProperty == null) throw new InvalidProgramException(view.EntityType.Name + "类没有设置 Title 属性。");

            var ddl = new ComboListControl
            {
                InnerListView = view,
                Name = "下拉列表",
                VerticalAlignment = VerticalAlignment.Center,
                MinWidth = 150,
            };

            ddl.DataContext = view;
            ddl.SetBinding(ComboListControl.TextProperty, "CurrentObject." + titleProperty);

            //当 View 发生 Refreshed 事件时，很可能表示有底层数据改变了，但是没有级联通知到界面上，
            //所以当 View 的控件被 Refresh 后，这个下拉框也需要主动进行刷新。
            view.Refreshed += (o, e) =>
            {
                ddl.GetBindingExpression(ComboListControl.TextProperty).UpdateTarget();
            };

            return ddl;
        }
