1模拟网易邮箱实现全选，全不的功能（服务端和客户端）

Demo.aspx

<head runat="server">
    <title></title>
    <script type="text/javascript" >
        function chage(sender) {
            var table = document.getElementById("GridView1");
            for (var i = 1; i < table.rows.length; i++) {
                table.rows[i].cells[0].getElementsByTagName("input")[0].checked = sender.checked;
            }
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <br />
        <br />
        <asp:SqlDataSource ID="SqlDataSource1" runat="server"
            ConnectionString="<%$ ConnectionStrings:studentConnectionString3 %>"
            SelectCommand="SELECT [sname], [sex], [age], [sid] FROM [student]"></asp:SqlDataSource>
        <asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1">
            <Columns>
                <asp:TemplateField>
                    <HeaderTemplate>
                        <asp:CheckBox ID="CheckBox2" runat="server" AutoPostBack="True"
                            Xoncheckedchanged="CheckBox2_CheckedChanged1" />
                        <br />
                        <input id="Checkbox3" type="checkbox" Xonclick="chage(this)" />
                    </HeaderTemplate>
                    <ItemTemplate>
                        <asp:CheckBox ID="CheckBox1" runat="server" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
        <br />
        <br />
    </div>
    </form>
</body>

Demo.aspx.cs

protected void CheckBox2_CheckedChanged1(object sender, EventArgs e)
        {
             CheckBox ckb= sender as CheckBox;
             foreach(GridViewRow row in this.GridView1 .Rows )
             {
                 if(row .RowType ==DataControlRowType .DataRow )
                 {
                     (row.FindControl("CheckBox1") as CheckBox).Checked = ckb.Checked;
                 }
             }

}

2 使用DataList实现加入购物车，编辑，删除，更新，取消功能。要求连一个产品表。

Demo.aspx

<head runat="server">
    <title></title>
    <style type="text/css">
        .style1
        {
            width: 99px;
        }
    </style>
</head>
<body>
    <form id="form1" runat="server">
    <div>

        <asp:DataList ID="DataList1" runat="server"
            Xoneditcommand="DataList1_EditCommand" Xonitemcommand="DataList1_ItemCommand"
            Xonupdatecommand="DataList1_UpdateCommand"
            Xondeletecommand="DataList1_DeleteCommand">
            <EditItemTemplate>
                <table style="width:100%;">
                    <tr>
                        <td class="style1">

                        <td>
                            <asp:TextBox ID="txtname" runat="server" Text='<%# Eval("sname") %>'></asp:TextBox>

                        </td>
                    </tr>
                    <tr>
                        <td class="style1">

                        </td>
                    </tr>
                </table>
            </EditItemTemplate>
            <ItemTemplate>
