Checbox在GridView中的应用

先看效果图：

前台代码：样式自己定义哦！

       <div style="text-align: center; width: 80%">            <yxy:HkrGridView ID="tabGridView1" runat="server" AutoGenerateColumns="False" Width="100%"                OnRowDataBound="HkrGridView1_RowDataBound" OnRowCreated="HkrGridView1_RowCreated"                ShowHeader="True" AllowPaging="false" DataKeyNames="keyId" ShowFooter="false">                <Columns>                    <asp:BoundField>                        <ItemStyle HorizontalAlign="Center" Width="5%" />                    </asp:BoundField>                    <asp:TemplateField>                    <ItemTemplate>                    <a href='<%#DataBinder.Eval(Container.DataItem,"newName")%>' ><%#DataBinder.Eval(Container.DataItem,"oldName")%></a>                    </ItemTemplate>                    </asp:TemplateField>                 <asp:BoundField DataField="memo">                        <ItemStyle Width="20%" HorizontalAlign="left" />                    </asp:BoundField>                    <asp:TemplateField>                        <ItemTemplate>                            <asp:CheckBox ID="CheckBox" runat="server" />                        </ItemTemplate>                        <ItemStyle HorizontalAlign="Center" Width="5%" />                    </asp:TemplateField>                </Columns>                <FooterStyle ForeColor="Red" HorizontalAlign="Center" Font-Bold="true" />            </yxy:HkrGridView>            <div id="DivOne" style="text-align: right">                <asp:CheckBox ID="CheckBoxAll" runat="server" Text="全选" Width="80px" AutoPostBack="True"                    OnCheckedChanged="CheckBoxAll_CheckedChanged" />                <asp:CheckBox ID="CheckBox1" runat="server" Text="反选" Width="80px" AutoPostBack="True"                    OnCheckedChanged="CheckBox1_CheckedChanged" />                                   <asp:Button ID="Button1" runat="server" Text="取　消" CssClass="Button" OnClick="Button1_Click" />            </div>        </div>

后台代码：
