Disable Browser Back Button Using Javascript ASP.NET

This example explains how to Disable Browser Back Button Using Javascript In ASP.NET. to avoid user going to previous page by clicking on back button of browser, for this we need to use javascript to prevent user navigating to previous page by hitting back button.

Disable Browser Back Button Using Javascript
Just put this javascript on the html section of aspx page above head section

<script type = "text/javascript" >
function disableBackButton()
{
window.history.forward();
}
setTimeout("disableBackButton()", 0);
</script>


We need to put it on the html section of the page which we want to prevent user to visit by hitting the back button

Complete code of the page looks like this
<%@ Page Language="C#" AutoEventWireup="true"
CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!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>Untitled Page</title>
<script type = "text/javascript" >
function disableBackButton()
{
window.history.forward();
}
setTimeout("disableBackButton()", 0);
</script>
</head>
<body onload="disableBackButton()">
<form id="form1" runat="server">
<div>
This is First page <br />
<br />
Go to Second page
<br />
<br />
<asp:LinkButton ID="LinkButton1" runat="server"
PostBackUrl="~/Default2.aspx">Go to Second Page
</asp:LinkButton></div>
</form>
</body>
</html>

If you are using firefox then use <body onunload="disableBackButton()"> instead of onload

If you want to disable back button using code behind of aspx page,than you need to write below mentioned code

C# code behind 
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
string strDisAbleBackButton;
strDisAbleBackButton = "";
ClientScript.RegisterClientScriptBlock(this.Page.GetType(), "clientScript", strDisAbleBackButton);
}

VB.NET code behind 
Protected Overloads Overrides Sub OnPreRender(ByVal e As EventArgs)
    MyBase.OnPreRender(e)
    Dim strDisAbleBackButton As String
    strDisAbleBackButton = ""
    ClientScript.RegisterClientScriptBlock(Me.Page.[GetType](), "clientScript", strDisAbleBackButton)
End Sub


We can also achieve this by disabling browser caching or cache by writing this line of code either in Page_load event or in Page_Init event

protected void Page_Init(object Sender, EventArgs e)
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
Response.Cache.SetNoStore();
}
Doing this,user will get the page has expired message when hitting back button of browser


Have fun

    Hi Amit,

    I have tried both of your solutions however none of them is working for me. I am able to use 'Back' button while i m on the second page.

    What I am doing is, I created a simple HTML/JS page with one hyperlink to another dummy page with just text message in it. Now, while I am on the second page, my browser does "Allow" me to move back by clicking on the 'Back' button.

    I tried C# version by pasting the C# code in page load as well as init of second page, but no success.

    Can you help me?

    Thanks,
    Sumeet

    @sumeet:

    Which browser u r using ? if you are using firefox than u need to write onunload instead of onload

    Also check whether javascript is enabled in your browser or not ?

    I've checked the code again and it's working fine for me in IE or Firefox

    Check this sample code

    And do let me know whether it works for you or not ?

    Do you know any way by which I can trap the Back button when it is clicked so that I can show an alert message to the user.

    Also by using above code I have noticed that although the page does not reside in Temporary folder however, is there any possibility that I can also deny it from storing in the "Drop down" of BACK button??

    Please suggest.


    Thanks,
    Sumeet

    Amit,
    What if the page you are trying to disable the back button for is just a content place holder on a master page, and the body tag is located in the master page. I don't want to disable the back button on my entire site, just when the user submits a specific request.
