这篇与前一篇改进部分，也许大家会留意到动画演示，主要是GridVeiw的更新与删除会在每row都有。因此Insus.NET把它抽取出来，放在GridView外。致于一次性更新多笔记录，Insus.NET在很早之前已经录制过视频：http://www.cnblogs.com/insus/articles/1400150.html 。还有一个就是删除，在每row第一列放了一个CheckBox，让用户可以选择记录进行删除。

View Code <asp:TemplateField>
                        <ItemStyle BorderWidth="1" BorderColor="#c0c0c0" Width="1%" />
                        <ItemTemplate>
                            <asp:CheckBox ID="CheckBox1" runat="server" onclick="Javascript:changeRowBgColor(this)" />
                        </ItemTemplate>
                    </asp:TemplateField>

删除前提示用户确认之后，再删除，但是在这里遇上一个问题，就是首先判断是否有选择记录，再confirm用户确认删除

还有一点要注意的地方，就是选择CheckBox之后，行可以Highlight，实现方可以参考：http://www.cnblogs.com/insus/archive/2011/09/07/2169742.html
