The below sample javascript code used to disable the browser back button in the asp.net applications. so that we can restrict the user to go back by pressing the browser back button. Include the below code in the Master page
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="WebApplication1.Site1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript">
function DisableBack() {
window.history.forward();
}
DisableBack();
window.onload = DisableBack;
window.onpageshow = function(evt) {
if (evt.persisted) DisableBack();
}
window.onunload = function() { void (0); }
</script>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
