与SqlDataSource绑定的GridView...
其中增加了两列TemplateField...其中有TextBox...具体效果如图：
现在想实现这样一个效果：当商品数量TextBox和下一列数据不一致时...
此行背景色变化，并且最后一列变成有改动...
补充说明：此页面继承母版页...希望大家多多帮忙...尽量提供代码...

刚开始的时候落下了：TextBox中AutoPostBack="true"
又给amandag发了封私信...打扰了...现在明白了...
谢谢大家...
结帖去了呃...说点题外话...是不是其实这样做不好啊？每次都得给服务器发送请求...
得抓紧学习javascript和ajax之类的技术了...
