XAF中如何制作弹出窗体选择数据到ListView列表

1.问题：

         有多对对关系对象，想为从对象选择数据录入从别的相关对象。

2.实现思路：

 　　 A.弹出选择窗体，从中选出所需记录

       B.将A和B组合为从对象，保存

       C.修改主从对象列表为可编辑（在View 中 Item_Detail_ListView设置为可编辑）

3.代码实现

   public partial class MP_Item_SelectOrderVC : ViewController
    {
        public MP_Item_SelectOrderVC()
        {
            InitializeComponent();
            RegisterActions(components);
        }

        protected override void OnActivated()
        {
            base.OnActivated();
            //按鈕在ViewId == "MP_Item_MP_ItemDetailCollection_ListView" 顯示
            pwsaSelectOrder.Active.SetItemValue("ViewId", View.Id == "MP_Item_MP_ItemDetails_ListView");// Application.FindListViewId(typeof(MP_ItemDetail)));

            //啟用Lookup查詢
            if (View.Id == Application.FindListViewId(typeof(MP_MRF)) && Frame.Template is ILookupPopupFrameTemplate)
            {
                ((ILookupPopupFrameTemplate)Frame.Template).IsSearchEnabled = true;
                ListView listView = ((ListView)View);
                listView.CollectionSource.Criteria.Add("EmptyCollectionCriteria", CollectionSource.EmptyCollectionCriteria);
                listView.CollectionSource.Criteria.Changed += delegate(object sender, EventArgs e)
                {
                    //if (!ReferenceEquals(listView.CollectionSource.Criteria[FullTextSearchCriteriaBuilder.CriteriaName], null))
                    if (!ReferenceEquals(listView.CollectionSource.Criteria[FilterController.FullTextSearchCriteriaName], null))
                    {
                        listView.CollectionSource.Criteria.Remove("EmptyCollectionCriteria");
                    }
                    else
                    {
                        if (!listView.CollectionSource.Criteria.ContainsKey("EmptyCollectionCriteria"))
                        {
                            listView.CollectionSource.Criteria.Add("EmptyCollectionCriteria", CollectionSource.EmptyCollectionCriteria);
                        }
                    }
                };

        }
