Move user to next page after a certain period of time...

use page timeout using javascript for moving next page after some time

In addition to what Shrikant suggests, you might want to do more to prevent and/or detect cheating. JavaScript can easily be figured out.

You could compare the time that an answer is received by the server and if it is sufficiently past the time period it is supposed to be then there is reason to suspect cheating, but you can't assume someone is guilty since the problem might be a bad connection.

I think it would work to do this from the server instead of using JavaScript but I don't know ASP well enough to suggest how to do it. You will need to use a timer in the server.

If you want to show a countdown timer then you probably want to use JavaScript for that.

Hi,
  The following javascript is used to redirect the user to another page after 60 seconds. 
window.setTimeout('window.location.href=\"WebPage1.aspx\"',60000);
function Timer()
{
window.setTimeout('UpdateLabel()',1000);
}
function UpdateLabel()
{
var label = document.getElementById('<%=Label1.ClientID %>');
label.innerHTML = parseInt(label.innerHTML) - parseInt('1');
window.setTimeout('UpdateLabel()',1000);
}

1. Set timer to 60 seconds which will redirect the user to WebPage1.
2. Call the UpdateLabel Function each second to show the decremental timer to the user
3. Get the label object
4. Decrease the label value by 1
5. Recall this function every 1 seconds.
