关于GridView无法进行编辑、删除的问题（有点特殊，因为我的GridView是动态绑定数据的）

Question

我的数据是从数据库里找到并绑定到GridView上的，我需要对这些数据进行编辑、删除，怎么才能实现？也就是说GridView的数据源是动态的，这时候我需要编辑、删除怎么实现？？？

Answer 1

你查找的肯定是有个标识的吧，比如ID，那就根据ID，来操作不就可以了嘛

Answer 2

什么意思哦？一般的GridView是直接绑定数据源，在绑定数据源的时候可以点击高级把那段允许编辑、删除的选项选上就可以了但现在是未绑定数据源？？？该怎么实现啊？？

Answer 3

是不是在Gridview中没有设置datakeys

Answer 4

不知所云
楼主
说清楚点吧
 GridView 不都是gridView.datascoure=
   不就都是动态数据么
  你指的是个啥意思
  发代码

Answer 5

GridView“GridView1”激发了未处理的事件“RowEditing”。 报错就是这个

Answer 6

给你一个建议
  把按钮那一列改成模板列
     源码会变成<asp:linkbutton ...  commanName='delete'>
 然后你在gridView事件中 ：
  if(e.commanName=='delete')
{
获取此行数据ID，执行delete()
}

Answer 7

你这个错误是因为你启用了gridview编辑功能
   所以gridview 源码中已经调用了rowediting方法
 你在设计页面找到gridview的rowedinting事件
 双击就不会报错了
 你可以在这个方法里面写你想要实现的功能
