Hi,
I am developing an on line test application. All test are timed. Duration is 60 minutes.. I want to implement countdown time which decreases by seconds. Somewhere on my page time remaining should be displayed. Like 59:59, 59:58, 59:57... After 60 mins is over the test should automatically be submitted. Before 60 mins also we can also submit the test.

You can use Timer Control by using ajax controls

ASP.NET

    <asp:timer id="Timer1" runat="server" interval="1000" ontick="Timer1_Tick" xmlns:asp="#unknown"></asp:timer>
<asp:lable id="Lable1" runat="server" xmlns:asp="#unknown" />

Add ontick event code in cs file:

C#

protected void Timer1_Tick(object sender, EventArgs e)
       {
            int seconds;
           if (Convert.ToString(Label1.Text) != "")
           {
               seconds = int.Parse(Label1.Text);
           }
           else
           {
               seconds =Convert.ToInt32(defaultTimer);//set some time count in default timer
           }
           Session[timeout"] = (seconds - 1).ToString();
           if (seconds> 0)
           {

               Label1.Text = (seconds - 1).ToString();

           }
           else
           {
               Timer1.Enabled = false;
               
           }
       }

you can use timer control (ajax extension control)

ASP.NET

<asp:timer xmlns:asp="#unknown">
       ID="Timer1" runat="server" Interval="1000" >
   </asp:timer>
