How to Refresh Grid Auto........


add this method.

  //Set and start the timer
        private void SetTimer()
        {
            DispatcherTimer dispatcherTimer = new DispatcherTimer();
            dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
            dispatcherTimer.Interval = new TimeSpan(0, 0, 60);
            dispatcherTimer.Start();
        }

create this Event where you want
 protected void dispatcherTimer_Tick(object sender, EventArgs e)
        {
           btnSearch_Click(null,null);
        }
