in the aspx page do this. Can't remember how to do timers off the top of my head but you should be able to get the point.

<script language=java>
alert('<% writeDuration();%>')
</script>

and then in the code behind put this function

public void writeDuration(){
int duration;
// get the duration from the database then

Response.Write(duration.ToString());

}

The best way is to use an HTML control instead of Web control
use text filed from HTML tab instead of TextBox in Web Controls Tab
and then right click on it -> run as server control .
then you can use it as a server control (in asp.net) and as an html control in javascript.
You can get it in javascript by document.formname.fieldname
where formname is the form name , and field name is the name of the text filed you created.
and user settimeout(func,1000) which execute the func every 1 second and display the time in the text field through the defintion of the func.
