无法取出datalist里的CheckBox状态值，做批量删除遇到的问题

实际上我是想做个批量删除
结果调试中无论如何也取不到datalist里CheckBox的选中状态，有没有高人能帮我分析出原因
ASPX页面代码
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="批量删除" OnClick="Button1_Click" />
    <asp:DataList ID="DataList1" runat="server" CellPadding="4" ForeColor="#333333" Width="100%"  >
                                            <HeaderTemplate>
                                            <table width="100%"  border="0" cellpadding="0" cellspacing="0">
                                                <tr>
                                                    <td  style="width:5%">删除</td>

                                                </tr>
                                            </table>
                                            </HeaderTemplate>
                                            <ItemTemplate>

                                                        <asp:CheckBox ID="CheckBox1" runat="server"  Text="aa"  />
                                                        <asp:Label ID="Label1" runat="server"  Text='<%# Eval("xmname")%>'></asp:Label>

  1.   

    try protected void Page_Load(object sender, EventArgs e) 
        { 
    if(!Page.IsPostBack)//====
            top_link_disp(); 
        } 
      

  2.   


    protected void Page_Load(object sender, EventArgs e) 
        { 
           if(!Page.IsPostBack)
           {
            top_link_disp(); 
           }    }

    的确如二楼所说
    我在datalist绑定数据前面的时候没有加页面post判断
    结构每次刷新页面CheckBox都是新生成的....
    感谢二楼的关注
