修改数据 datagridview 绑定数据不刷新
目的是想用线程十秒绑定一次数据 显示状态

      private void Index_Load(object sender, EventArgs e)
    ｛
          Thread thread = new Thread(new ThreadStart(RunsOnWorkerThread));
                        thread.Start();
       ｝
        //委托
        private void RunsOnWorkerThread()
        {

            MethodInvoker mi = new MethodInvoker(dataSet1);

            BeginInvoke(mi);

        }



        //设备提醒
        void dataSet1()
        {
            if (AppRun)
            {
                dataGridView1.Rows.Clear();
                string sql = " select tw.*,b.gprs_number from dbo.Temp_WaterState as tw join basis_use_water_origin_rtu as b on  tw.T_ClientID=b.clientid";
                DataSet dt = DHelper.GetDataSet(sql);//帮助类
                int cot = dt.Tables[0].Rows.Count;
                dataGridView1.Rows.Add(cot);
                for (int i = 0; i < cot; i++)
                {
                    // DefaultCellStyle.BackColor = Color.Red;


                    dataGridView1.Rows[i].Cells["rtu"].Value = dt.Tables[0].Rows[i]["T_ClientID"] + "";
                    dataGridView1.Rows[i].Cells["jcd"].Value = DHelper.getName(dt.Tables[0].Rows[i]["T_ClientID"] + "");
                    dataGridView1.Rows[i].Cells["gxsj"].Value = dt.Tables[0].Rows[i]["T_Time"] + "";

                    dataGridView1.Rows[i].Cells["kzq"].Value = DHelper.getKZQ(kzq);// 状态。 正常还是中断
                    int wl = Convert.ToInt32(dt.Tables[0].Rows[i]["T_GPRSState"]);
                    if (wl == 0)

用虚模式比较好!
