This posible using JQuery.

See the below code:- 


<html xmlns="http://www.w3.org/1999/xhtml">

<head id="Head1" runat="server">

    <title></title>



    <script type="text/javascript" language="Javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>



    <script type="text/javascript" language="javascript">

        idleTime = 0;



        $(document).ready(function() {

            //Increment the idle time counter every minute.

            var idleInterval = setInterval("displayMessage()", 10000); // 10 Seconds



            //Zero the idle timer on mouse movement.

            $(this).mousemove(function(e) {

                idleTime = 0;

            });



            $(this).keypress(function(e) {

                idleTime = 0;

            });

        })



        function displayMessage() {

            idleTime = idleTime + 1;

            if (idleTime > 6) {

                alert('Idle for for 1 min.');

                idleTime = 0;

            }

        }

    </script>



</head>

<body>

    <form id="form1" runat="server">

    <div>

    </div>

    </form>

</body>

</html>

Hi Govind,
Once go through this code. This may help you.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">

jQuery(document).ready(function(e)
     {
     var tt_exp = "1"; //set the exp time in min 
     tt_exp     = (parseInt(tt_exp) * 60000); //set the time in microsecond 
     $(document).bind("idle.idleTimer", function(){
     $("#divId").html("Time Out"); //here you can attach any function for timeout action  
    });
$(document).bind("active.idleTimer", function(){
    //alert("You are alive ")
     $("#divId").html("You are alive"); //This means the session is alive 
    });
    jQuery.idleTimer(tt_exp);
  });
</script>


Thanks,
Prabhu Kiran Bommareddy

Hi,
Save the belove code as :"idle-timer.js" (JavaScript File) and try it.


( function( $ ) {

$.idleTimer = function( firstParam, elem, opts ) {

        // defaults that are to be stored as instance props on the elem
        opts = $.extend( {
                startImmediately: true,   //starts a timeout as soon as the timer is set up
                idle: false,              //indicates if the user is idle
                enabled: true,            //indicates if the idle timer is enabled
                timeout: 30000,           //the amount of time (ms) before the user is considered idle
                events: "mousemove keydown DOMMouseScroll mousewheel mousedown touchstart touchmove" // activity is one of these events
        }, opts );


        elem = elem || document;

        var jqElem = $( elem ),
                obj = jqElem.data("idleTimerObj") || {},

                /* (intentionally not documented)
