Hi,

you can do it in javascript.Here 'm providing code for try that

ASP.NET

<head runat="server">
    <title></title>
    <script language ="javascript">
        var sdf;
        function f1() {
            sdf = setTimeout("f2()", 300);
        }
        function f2() {
            location.href = "default2.aspx";
        }
    </script>
</head>
<body onload="f1()">
    <form id="form1" runat="server">
    <div>

    </div>
    </form>
</body>
</html>

In the above code you've to set what is your time requirement.
The time here is in millisec so you can give correct time for it.

Here im giving for count down time for you requirement.

HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script language ="javascript" >
        var tim = 10000;
        var timset;
        function f1() {
            timset = setInterval("f2()", 1000);
        }
        function f2() {

            tim = parseInt(tim) - 10;
            if (parseInt(tim) < 0) {
                clearInterval(timset);
            }
            else {
                document.getElementById("timershow").value = tim;
                timset = setInterval("f2()", 1000);
            }

        }
    </script>
</head>
<body onload ="f1()" >
    <form id="form1" runat="server">
    <div>
      <input type ="text" id="timershow" />
    </div>
    </form>
</body>
</html>

All the best

You try this for decrease order..You have to edit this code for you requirement...

XML

<html>
<body>
<div id="countdown"></div>
<div id="notifier"></div>

<script type="text/javascript">

(function () {
  function display( notifier, str ) {
    document.getElementById(notifier).innerHTML = str;
  }

  function toMinuteAndSecond( x ) {
    return Math.floor(x/60) + ":" + (x=x%60 < 10 ? 0 : x);
  }

  function setTimer( remain, actions ) {
    var action;
    (function countdown() {
       display("countdown", toMinuteAndSecond(remain));
       if (action = actions[remain]) {
         action();
       }
       if (remain > 0) {
         remain -= 1;
         setTimeout(arguments.callee, 1000);
       }
    })(); // End countdown
  }

  setTimer(20, {
    10: function () { display("notifier", "Just 10 seconds to go"); },
     5: function () { display("notifier", "5 seconds left");        },
     0: function () { display("notifier", "Time is up baby");       }
  });
})();

</script>
</body>
</html>
