You have to do this via script in the HTML. ASP.NET code runs ENTIRELY server-side. That means that is has absolutely no control over the client page once it's finished being sent, so your timer will never work.

I can't as I haven't done javascript or an ASP.NET app is years. I don't have an example, but if you Google "javascript timer" you can come up with examples quite easily.

maybe you can use server side coding. is suggest you make a hidden field for the timer for example label2 is assigned to count the timer but it is hidden and the user cannot see it.

XML

 if label1.text = "30" then
label1.visible = false
end if

Hi
First, know that ASP.NET label tag will be rendered as an html div or span.
Second, you dont need to setup a timer in your code behind. just trigger a javascript with either an input or an anchor or anything else.

Try this :

<input type="submit"  önclick="flick(yourlabelid);" value="hello" />
<a href="javascript:flick(yourlabelid); return false;">hello</a>
<div id="yourlabelid">content</div>

JavaScript

<script type="text/javascript">
function flick(id){
 hideLabel(id);
 var t=setTimeout("showLabel("+id+")",30000);
}
function hideLabel(id) {
document.getElementById(id).style.display = "none";
}
function showLabel(id) {
document.getElementById(id).style.display = "block";
}
</script>

in this example both input and anchor launch javascript function named flick. this function hides rendered label, waits 30 seconds and shows the label again.
