asp.net中使用repeater和PageDataSource搭配實現分頁代碼

代碼如下:
 PagedDataSource objPage = new PagedDataSource();

            DataView dv = bllBook.GetListByState("", true);
            //設置數據源
            objPage.DataSource =dv ;

            //允許分頁
            objPage.AllowPaging = true;

            //設置每頁顯示的項數
            objPage.PageSize = 10;

            //定義變量用來保存當前頁索引
            int CurPage;
            int RecordCount;
            int PageCount = objPage.PageCount;

            RecordCount = dv.Count;

            //判斷是否具有頁面跳轉的請求
            if (Request.QueryString["Page"] != null)
            {
                CurPage = Convert.ToInt32(Request.QueryString["Page"]);
            }

            else
            {
                CurPage = 1;
            }

            //設置當前頁的索引
            objPage.CurrentPageIndex = CurPage - 1;

            //顯示狀態信息
            lblCurPage.Text = "第  " + CurPage.ToString() + "/" + PageCount.ToString() + "頁    共  " + RecordCount.ToString() + " 記錄 ";

            //如果當前頁面不是首頁
            if (!objPage.IsFirstPage)
            //定義 "上一頁 "超級鏈接的URL為：當前執行頁面的虛擬路徑,并傳遞下一頁面的索引值
            {
                lnkPrev.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1);
                lnkFirst.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(1);
            }

            //如果當前頁面不是最后一頁
            if (!objPage.IsLastPage)
            //定義 "下一頁 "超級鏈接的URL為：當前執行頁面的虛擬路徑,并傳遞下一頁面的索引值
            {
                lnkNext.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage + 1);
                lnkLast.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(PageCount);
            }

            //進行數據綁定
            Repeater1.DataSource = objPage;
            Repeater1.DataBind();
