获得编号 这个编号要在GridView中设置一下属性 DataKeyNames 这里设置的是数据库的主键ID
4

e.RowIndex 这个通过 事件源 e 来获得RowIndex 代表 行号

这里是取得编辑时的值

通过 Rows[e.RowIndex] 当时事件的行
9
//
FindControl[""]代表获取GridView内的控件名称，如FindControl("txtshehui")
10
//
我们取出来的控件的类型都是Control类型 的,所以,我们要根据我们定义的控件类型去转换,这里是TextBox类型 (注意 括号的加法)
11
//
如果是其它类型,就转换成其它的类型就可以了如DropDownList
