你好MANI，



请写你的代码

Hi MANI,

Please write your code inside

protected void Page_Load(object sender, EventArgs e)
        {

            if (!IsPostBack)
            { 
            //Write the timere code here. 
            //This code block will be executed when the page will be loaded first time. 
            }
        }

请尝试以下代码：

Try following code:

protected void Page_Load(object sender, EventArgs e)
{

    if (!IsPostBack)
    {
    //Write the timere code here.
    //This code block will be executed when the page will be loaded first time.
        System.Timers.Timer aTimer = new System.Timers.Timer();
        aTimer.Elapsed += new ElapsedEventHandler(TimerCharts_Tick);
        // Set the Interval to 5 seconds.
        aTimer.Interval = 10000;
        aTimer.Enabled = true;
    }
}

protected void TimerCharts_Tick(object sender, EventArgs e)
{
    GetValidCharts();
}

从aspx页面删除控件：

Remove the control from aspx page :

<asp:Timer ID="TimerCharts" runat="server" Interval="300000" OnTick="TimerCharts_Tick"  >
          </asp:Timer>
