前面我們提到了，如果想要一次將從TextBox資訊新增到GridView的幾行資料記錄新增到資料庫中，我們在設計ASP.NET的頁面時，建議採用AJAX技術，進行區域性資料重新整理。

如圖所示：【建議在IE瀏覽器下執行】以下都是控制元件的拖動，大家都懂的。

另外，在protected void Page_Load(object sender, EventArgse)事件中，定義如下：

        {

            if(!IsPostBack)

            {

                DataSetdsGv = new DataSet();

                DataTable

                dt.Columns.Add("userName",typeof(string));//列

                dt.Columns.Add("sex",typeof(string));

                dt.Columns.Add("address",typeof(string));

                dt.Columns.Add("gradeID",typeof(int));

                dsGv.Tables.Add(dt);

                ViewState["dsGv"

                bind();

            }

        }

這樣每一新增一個數據，就會在原來的基礎上加入一條記錄，而不會每次都重新整理頁面，導致每次都是顯示一條資料。

這樣每次填寫完資訊，點選【新增】，便顯示在GridView中【本案例將gridview命名為GvInformation】

【注意】寫在if(!IsPostBack)中。。。 。                                                               

protected void bind() //繫結顯示資料

        {

            if(((DataSet)ViewState["dsGv"]).Tables[0].Rows.Count > 0)

            {

                GvInformation.DataSource = ((DataSet)ViewState["dsGv"]);

                GvInformation.DataBind();

            }

            else

            {

                GvInformation.DataSource = null;

                GvInformation.DataBind();

            }

        }

///<summary>

        ///新增按鈕

        ///</summary>

        ///<param name="sender"></param>

        ///<paramname="e"></param>

        protectedvoid Button1_Click(objectsender,EventArgs e)//新增按鈕操作

        {

            if(TxtGradeID.Text.Trim() !=""&& Convert.ToInt32(TxtGradeID.Text.Trim())> 0 &&int.Parse(TxtGradeID.Text.Trim())< 9)

            {

                DataRowdr =((DataSet)ViewState["dsGv"]).Tables[0].NewRow();//創ä¡ä建¡§一°?個?新?紀¨ª錄?，ê?並¡é修T改?紀¨ª錄?的Ì?值¦Ì

                dr.ItemArray = newobject[] {  //這個方法很多，您也可以用其他方法

            TxtName.Text.Trim(),

            TxtSex.Text.Trim(),

            TxtAddress.Text.Trim(),

            int.Parse(TxtGradeID.Text.Trim())  //轉換

            };

                ((DataSet)ViewState["dsGv"]).Tables[0].Rows.Add(dr); //填充到表中

                bind();

                TxtName.Text = "";

                TxtGradeID.Text = "";

                TxtSex.Text = "";

                TxtAddress.Text = "";

            }

            else

            {

               message.AjaxResponeSrcipt(UpdatePanel1, this.GetType(),"請您填寫完整資訊");

            }

        }

//也許你會有疑問，為什麼我會通過一個GridView進行顯示，其實這樣的作用有：

//*****便於使用者在大量新增資料的時候，在表格中顯示了，容易檢查是否輸錯，便於修改

protected void BtnSubmit_Click(object sender, EventArgs e) //提交操作，儲存到資料庫中
