高手们，帮帮小妹吧，一开始GridView1_RowUpdating这里报错，后来改了改上面又报错了，急求高手指点 --------------------编程问答-------------------- GridView1数数看有没有8列(第1列是0),或者用FindControl试试 --------------------编程问答-------------------- 是8列，FindControl怎么试，我是新手，麻烦说的具体点，谢谢了 --------------------编程问答--------------------
((LinkButton)(e.Row.FindControl("ControlID"))).Attributes.Add("onclick", "return confirm('确定要删除吗？')");
试试 --------------------编程问答-------------------- Cells[7] 的下标是从0开始的，0就表示1，后面依次类推。 --------------------编程问答--------------------
这个可以++ --------------------编程问答-------------------- cell[7]问题。改为cell[6]吧！或者是Cell[7]不是LinkButton！
自己单步试试！ --------------------编程问答--------------------
+++ --------------------编程问答--------------------
我这么做之后，又报 未将对象引用设置到对象的实例这个错 --------------------编程问答-------------------- index取的不对，不是7，改为6 --------------------编程问答--------------------
((LinkButton)(e.Row.FindControl("ControlID"))).Attributes.Add("onclick", "return confirm('确定要删除吗？')");中的ControlID你改成了gridview中的LinkButton的ID了吗?
补充：.NET技术 , ASP.NET
