<asp:ListView runat="server" ID="_simpleTableListView">   <LayoutTemplate>     <table>       <thead>         <tr>              <th id="Th1" runat="server">                  ID</th>              <th id="Th2" runat="server">                  StudentID</th>              <th id="Th3" runat="server">                  Name</th>              <th id="Th4" runat="server">                  Math</th>              <th id="Th5" runat="server">                  English</th>              <th id="Th6" runat="server">                  Chinese</th>         </tr>       </thead>       <tbody>         <asp:PlaceHolder runat="server" ID="itemPlaceholder" />       </tbody>     </table>   </LayoutTemplate>   <ItemTemplate>     <tr>         <td>             <asp:Label ID="IDLabel" runat="server" Text='<%# Eval("ID") %>' />         </td>         <td>             <asp:Label ID="StudentIDLabel" runat="server" Text='<%# Eval("StudentID") %>' />         </td>         <td>             <asp:Label ID="NameLabel" runat="server" Text='<%# Eval("Name") %>' />         </td>         <td>             <asp:Label ID="MathLabel" runat="server" Text='<%# Eval("Math") %>' />         </td>         <td>             <asp:Label ID="EnglishLabel" runat="server" Text='<%# Eval("English") %>' />         </td>         <td>             <asp:Label ID="ChineseLabel" runat="server" Text='<%# Eval("Chinese") %>' />         </td>     </tr>   </ItemTemplate> </asp:ListView> <asp:DataPager ID="DataPager2" runat="server"     PagedControlID="_simpleTableListView" PageSize="2"     onprerender="DataPager2_PreRender">     <Fields>         <asp:NextPreviousPagerField ButtonType="Button" ShowFirstPageButton="True"             ShowLastPageButton="True" />     </Fields> </asp:DataPager>

後台代碼：
   

代碼如下

複製代碼

protected void DataPager2_PreRender(object sender, EventArgs e)     {         BindData();     }  private void BindData()     {   using (OleDbConnection conn = new OleDbConnection(OleDbHelper.ConnectionString))   {    string sql = "select * from studentscore";    OleDbDataAdapter dp=new OleDbDataAdapter(sql,conn);    DataTable dt = new DataTable();    dp.Fill(dt);    _simpleTableListView.DataSource = dt;    _simpleTableListView.DataBind();   }     }

注意：使用本方法，不需要在頁面的Page_Load事件中綁定資料到ListView控制項，
否則分頁會有問題。

第2種方法：

代碼如下	複製代碼
protected void Page_Load(object sender, EventArgs e)     {         if (!IsPostBack)         {             BindData();         }     }  protected void _simpleTableListView_PagePropertiesChanging(object sender, PagePropertiesChangingEventArgs e)     {         DataPager2.SetPageProperties(e.StartRowIndex, e.MaximumRows, false);         BindData();     }
