Hi, you can use timer control it allow you to do postbacks at certain intervals. If used together with UpdatePanels, which is the most common approach, it allows for timed partial updates of your page, but it can be used for posting back the entire page as well.

Here is a small example of using the Timer control. It simply updates a timestamp every 5 seconds.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:Timer runat="server" id="UpdateTimer" interval="5000" ontick="UpdateTimer_Tick" />
<asp:UpdatePanel runat="server" id="TimedPanel" updatemode="Conditional">
<asp:AsyncPostBackTrigger controlid="UpdateTimer" eventname="Tick" />
<asp:Label runat="server" id="DateStampLabel" />

You can put your code here to stop exam and display exam result,

protected void UpdateTimer_Tick(object sender, EventArgs e)
DateStampLabel.Text = DateTime.Now.ToString();

you can use timer control it allow you to do postbacks at certain intervals. if time interval is completed then it automatically stop the test and submit button will disable for submit the answer. and u can directly show the result .

Thanks And Regards.
