Question

See more:

I have a asp.net page containing a LABEL control showing current time.

The way i used for it is,for each timer TICK event,set label.text as Now Time,

The way is enough for me,but when i scroll down to end of the page,its automatically goto beginning of the page after 60 seconds,so that i cant even view the details in the end of the page.

what i can do to avoid this,this also affecting some text fields in the page.
i am using seperate update panel for Timer and other controls

Please help me

You should control your page

               {}

Hi

You want to show server time or client time?. Alternatively to timer control.

Here is some example showing both client and server time using javascript and ajax.

Have a div sections in the aspx page as shown.

XML

<div><label >Client Time</label><div id="time2"></div></div>
<div><label>Server Time</label>
<asp:TextBox runat="server" ClientIDMode="Static" ID="time1" EnableViewState="false">
</div>

Have this javascript in the header section. If you use master pages then in the master header section.

C#

<script type="text/javascript">
    function getServerTime() {
    var timebox = document.getElementById('time1');
    var xmlhttp;
    if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    }
    else {
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function () {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
            timebox.innerHTML = xmlhttp.responseText;
        }
        else {
        }
    }
    xmlhttp.open("GET", "Default2.aspx", true);
    xmlhttp.send();
}
function showTime() {
    var d = new Date();
    var curr_hour = d.getHours();
    var curr_min = d.getMinutes();
    var curr_seconds = d.getSeconds();
    if (document.getElementById('time2') != null) {
        document.getElementById('time2').innerHTML = curr_hour + " : " + curr_min + " : "+curr_seconds;
    }
}
setInterval(showTime, 1000); //runs every 1 sec in a separate thread
setInterval(getServerTime, 1000);//runs every 1 sec in a separate thread
function test() {
    showTime();
    getServerTime();
}
</script>

The setInterval function run in separate thread. So it won't interfere with your page unnecessarily.

Add a new webform say Default2.aspx and in that page load event

C#

protected void Page_Load(object sender, EventArgs e)
{
    Response.Write(DateTime.Now.ToString("H : mm : ss"));
}

The Default2.aspx should not have any markup except the page directive

This will be called by the getServerTime javascript function using ajax every 1 sec.

on the body load event call both functions. <body onload="test();">

Hope this helps
