I am developing an online test system.
I have developed a timer using timer control.
The problem is when I start the test the page is getting refreshed automatically.
I want to stop auto refresh of timer.

//.aspx code

ASP

<asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" OnTick="Timer1_Tick"
                    Interval="1000">
<asp:Label ID="label_time"
                runat="server" Text=""></asp:Label>

//.aspx.cs code

C#

int totalSeconds = 0;
   int seconds = 0;
   int minutes = 0;
   string time = &amp;amp;quot;&amp;amp;quot;;



  protected void Page_Load(object sender, EventArgs e)
   {

           if (!Page.IsPostBack)
           {
               Session["time"] = 1800 ;


           }


      }


    protected void Timer1_Tick(object sender, EventArgs e)
   {
       Session["time"] = Convert.ToInt16(Session["time"]) - 1;
       if (Convert.ToInt16(Session["time"]) <= 0)
       {

          label_time.Text = "TimeOut!";
           insert_result();
           Response.Redirect("Show_result.aspx");
       }

       else
       {
           totalSeconds = Convert.ToInt16(Session["time"]);
            seconds = totalSeconds % 60;
            minutes = totalSeconds / 60;
            time = minutes + ":" + seconds;
           label_time.Text = time;
       }
   }

You have Timer's Tick event defined which means the code will get executed on every tick of the timer. That is why the page is getting refreshed. You should read how a timer control works first.

sir I have gone through many links and tutorials and finally implemented this code. Without tick event how will the time get decremented ?

If you are using time control then on tick event first of all you have to stop your timer in first line, then write line code which you want to execute in timer tick event, after that you have to start your timer in last line.

in between you want to stop your timer permanently, then you have to write Timer1.Enabled = false;

why do we need to stop timer? and yes what does stop permanently means for? if i stop the timer permanently then how it will display the time?

Mr. Mahesh Patel 18-Feb-13 8:19am

We have to stop timer because this event will occur at every time interval but my be possible that previous process may not completed. so system may get hang.

And yes, If you don't want to stop timer permanently, then don't do it dear.

Hi,

You should use your timer in UpdatePanel other than other controls on your page and if possible please use JavaScript timer so that it will not hit the server every time.

Please see this javascript code:-

XML

<html>
<head>
<title>Countdown</title>
<script type="text/javascript">
// set minutes
var mins = 5;

// calculate the seconds (don't change this! unless time progresses at a different speed for you...)
var secs = mins * 60;
function countdown() {
setTimeout('Decrement()',1000);
}
function Decrement() {
if (document.getElementById) {
minutes = document.getElementById("minutes");
seconds = document.getElementById("seconds");
// if less than a minute remaining
if (seconds < 59) {
seconds.value = secs;
} else {
minutes.value = getminutes();
seconds.value = getseconds();
}
secs--;
setTimeout('Decrement()',1000);
}
}
function getminutes() {
// minutes is seconds divided by 60, rounded down
mins = Math.floor(secs / 60);
return mins;
}
function getseconds() {
// take mins remaining (as seconds) away from total seconds remaining
return secs-Math.round(mins *60);
}
</script>
</head>
<body>

<div id="timer">
This is only valid for the next <input id="minutes" type="text" style="width: 14px; border: none; background-color:none; font-size: 16px; font-weight: bold;"> minutes and <input id="seconds" type="text" style="width: 26px; border: none; background-color:none; font-size: 16px; font-weight: bold;"> seconds.
</div>
<script>
countdown();
</script>

Thanks
