我想用javascript判断我选中的行是否删除 但是我点否它也能删除 为什么？
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[6].Attributes.Add("onclick", "javascript:return confirm('你确认要删除吗?')");
}

Cells[6]里是放的什么控件？button吗？
试试这样
(Button(e.Row.Cells[6].Controls[0])).Attributes.Add("onclick", "javascript:return confirm('你确认要删除吗?')");

#region 删除提示
protected void gv_Message_RowDataBound(object sender, GridViewRowEventArgs e)
{
LinkButton btn_del = (LinkButton)(e.Row.FindControl("LinkButton1"));
if (btn_del != null)
{
btn_del.Attributes.Add("onClick", "javascript:return confirm('你确定要删除吗?');");
}
}
#endregion

楼上正解,写在..DataBound()里面

你这样没提示

我的全部代码是这样的 红色的代码是我用来判断的

有啊
不然就把该列设置为模板列，但觉得没有必要。
2楼的不是告诉你的错误了吗？
为什么不改呢？

那种方法不行

我自己就是这样做的啊
可以提示的
