如何加载更多数据绑定？

Question

当我选择itemFooter时，数据绑定将获取数据并加载继续

    public void getFeed()
    {
        waittingopen();
        if (listRSS != null && listRSS.Count > 0)
        {
            List<Article> listArticle = getArticle();

            if (listArticle.Count > 0)
            {
                if (loadmor != null && list.Items.Contains(loadmor))
                {
                    list.Items.Remove(loadmor);
                }

                #region  add item
                for (int i = 0; i < listArticle.Count; i++)
                {
                    dataDetail dataDetail;
                    if (i == 0 && dtListBoxx.Count == 0)
                        dataDetail = new dataDetail { title = listArticle[i].title, feedName = listRSS[indexLoadmor].name, Type = "itemBigContent", isVisileLineLeft = System.Windows.Visibility.Collapsed, isVisileBook = System.Windows.Visibility.Collapsed };
                    else
                        dataDetail = new dataDetail { title = listArticle[i].title, feedName = listRSS[indexLoadmor].name, Type = "itemContent", isVisileLineLeft = System.Windows.Visibility.Collapsed, isVisileBook = System.Windows.Visibility.Collapsed };
                    dtListBoxx.Add(dataDetail);
                }
                #endregion

                if (intLoad == 0)
                {
                    listArticle.Clear();
                    listArticle = null;
                    indexLoadmor++;
                    intLoad++;
                    getFeed();
                }
                else
                {
                    intLoad = 0;
                    dataDetail dataLoadmoreItem = new dataDetail { Type = "itemFooter" };
                    dtListBoxx.Add(dataLoadmoreItem);

                    this.list.ItemsSource = dtListBoxx;
                }
                waittingClose();
            }
            else
            {
                getfeed = new Getfeed(listRSS[indexLoadmor].link.ToString(), "", listRSS[indexLoadmor].rid, intLoad);
                getfeed.onComplete += new Getfeed.DownloadComplete(getfeed_onComplete);
                if (intLoad == 1)
                    intLoad = 0;
            }
        }
    }

如何使用this.list.ItemsSource = dtListBoxx加载更多数据？我试过但是当dataDetail添加项目时，listbox没有更新

请帮助我！

使用ObservableCollection代替List。它会自动引发OnCollectionChanged事件，以通知视图集合中发生了一些更改。
