Answer 1

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
                {
                    if (this.GridView1.DataKeys[e.Row.RowIndex][1].ToString() == "管理员")
                    {
                        ((LinkButton)e.Row.FindControl("lbtnDel")).Visible = false;
                    }
                    else
                    {
                        ((LinkButton)e.Row.FindControl("lbtnDel")).Visible = true;
                    }
                }
            }
        }

Answer 2

1,3楼正解
2楼说AJAX，具体说说看，我想不出来怎么做。。

Answer 3

ajax不用考虑，不安全，网速慢显示不正常

Answer 4

这个在查询的时候就可以过滤
userName!='admin' 就行了
或者就用上面 一行一行判断

Answer 5

但是 【0】我发现不是遍历的Name 而是 userId  所以它报错啊 

Answer 6

[e.Row.RowIndex][???]你Name是第几列你就相应改一下就可以啦，列下标为0，从0开始计数

Answer 7

“System.ArgumentOutOfRangeException”类型的异常在 mscorlib.dll 中发生，但未在用户代码中进行处理其他信息: 索引超出范围。必须为非负值并小于集合大小。

Answer 9

this.GridView1.DataKeys[e.Row.RowIndex][1].ToString() 换成e.Row.Cells[1].Text，是我搞错了

Answer 10

你这里要这样用((Lable)e.Row.Cells[?].FindControl("lblName")).Text=="admin"

Answer 11

大哥还是不行啊  我DEBUG了一下发现e.Row.Cells[1].Text 总是为“”空啊,上面原因呢？

Answer 12

由于没有同名的lblName，这里((Lable)e.Row.FindControl("lblName")).Text=="admin"也行

Answer 13

使用<asp:BoundField DataField="Fil_Re" HeaderText="备注" />时，用e.Row.Cells[1].Text 
你这里使用了模板列，就要使用((Lable)e.Row.FindControl("lblName")).Text=="admin"了
