 三、

1）html代码

<asp:ButtonField ButtonType="Button" CommandName="observe" HeaderText="操作" Text="查看" />

2）

        protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName == "observe")
            {
                try
                {
                    int index = Convert.ToInt32(e.CommandArgument);
                    string LiencePlateNumber = ((Label)GridView1.Rows[index].Cells[1].FindControl("label2")).Text.ToString().Trim();
                    string CreateTime = ((Label)GridView1.Rows[index].Cells[7].FindControl("label8")).Text.ToString().Trim();
                    string url = "../Management/ExDetails.html?LiencePlateNumber=" + LiencePlateNumber + "&CreateTime=" + CreateTime;
                    string js = "window.open("../Management/ExDetails.html?LiencePlateNumber=" + LiencePlateNumber + "&CreateTime=" + CreateTime + "","_blank")";
                    ScriptManager.RegisterStartupScript(UpdatePanel1, GetType(), System.DateTime.Now.Ticks.ToString(), js, true);
                }
                catch (Exception ex)
                {
                    Logger.Write("后台查看异常详情失败，原因：" + ex.Message);
                    throw ex;
                }

            }
