ASP.NET简化编辑界面解决思路及实现代码(2)_实用技巧

分享到:
程序是需要不断改进,上午做了,下午再去看时,会觉它不够完美。
比如这个:http://www.jb51.net/article/33563.htm现在Insus.NET把它改为下面这个样子:
 

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下载地址。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。

<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.jb51.net/article/33558.htm
以下较完整代码,仅供参考:
