  • DataGridView实现倒计时功能(源码)

     需求:最近做一个即时通项目,需要结合OA项目;其中有一个待办事项需要倒计时,准备在DataGridView里展示,如图:

    第一步:绑定数据

      for (int intLoop = 1; intLoop <= 5; intLoop++)
                {
                    this.dgvSteps.Rows.Add(
                        Test.Properties.Resources.PROCESS_READY,
                        intLoop.ToString(),
                        "" + intLoop.ToString() + "个任务&为开始",
                        "{0}天{1}小时{2}分钟{3}秒",
                        "处理"
                        );
                }

    第二步:定义System.Threading.Timer(一定要在定义局部变量,不然会被回收的)

    DateTime dtStart;
            private System.Threading.Timer timerClose;
            private void btnStart_Click(object sender, EventArgs e)
            {
                AutoResetEvent autoEvent = new AutoResetEvent(false);
                timerClose = new System.Threading.Timer(new TimerCallback(timerCall), autoEvent, 1000, 1000);
                dtStart = DateTime.Now.AddHours(5);
            }
    
            private void timerCall(object obj)
            {
    
                TimeSpan ts = dtStart - DateTime.Now;
                if (ts < TimeSpan.Zero)
                {
                    for (int i = 0; i < this.dgvSteps.Rows.Count; i++)
                    {
                        this.dgvSteps.Rows[i].Cells[3].Value = "超时";
                    }
                }
                else
                {
                    for (int i = 0; i < this.dgvSteps.Rows.Count; i++)
                    {
                        this.dgvSteps.Rows[i].Cells[3].Value = string.Format("{0}天{1}小时{2}分钟{3}秒", ts.Days, ts.Hours, ts.Minutes, ts.Seconds);
                    }
                }
              
            }
