我有网格视图。当页面加载事件发生时，网格视图中的值会正确显示。但是当我尝试向该数据表插入一个新值时，它不起作用，只有插入的值显示并非数据表中的所有值。这个怎么解决？？我的代码：

   if (!IsPostBack)
        {
   SqlCommand cmd = new SqlCommand("SELECT QuestionID,Options from QuestMultiChoice where QuestionID= '"+ labelID.Text +"'", con);
            cmd.CommandType = CommandType.Text;
            SqlDataAdapter da1 = new SqlDataAdapter();
            da1.SelectCommand = cmd;

            da1.Fill(TempDTable);
            gvDetails.DataSource = TempDTable;
            gvDetails.DataBind();
}

   protected void imgbtnAdd_Click1(object sender, ImageClickEventArgs e)
    {
        DataTable TempDTable = new DataTable();

        if (ViewState["PdataTable1"] == null)
        {

            TempDTable.Columns.Add("QuestionID", typeof(string));
            TempDTable.Columns.Add("Options", typeof(string));
        }
        else
        {
            TempDTable = (DataTable)ViewState["PdataTable1"];
        }
        DataRow row = TempDTable.NewRow();
        TextBox txtftr = (TextBox)gvDetails.FooterRow.FindControl("txtftr");

        row["QuestionID"] = labelID.Text;
        row["Options"] = txtftr.Text;

        TempDTable.Rows.Add(row);
        //this.GridViewColumns.Visible = true;
        ViewState["PdataTable1"] = TempDTable;
        gvDetails.DataSource = TempDTable;
        gvDetails.DataBind();
    }

aspx 代码：
