Disable Browser Back Button Programmatically

Disable Browser Back Button Programmatically

Today I will show how to Disable Back Button of Browser Programmatically.

Concept:

We know that browser's back button can not be disabled because browser resides at user's machine and not on Server. All we can do is to prevent a page for being cached. So if a page is not being cached at client then browser back button will not allow a user to navigate to that page. 

How to do this:

Suppose you dont want the user to navigate to this Page1.aspx from Page2.aspx.

Use following 3 lines in HEAD section (HTML view) of Page1.aspx

<meta http-equiv="cache-control" content="no-store"/>

<meta http-equiv="expires" content="0"/>

<meta http-equiv="pragma" content="no-cache"/>

Then in the code behind inside Page_Load  event of Page1.aspx:

VB

Response.Cache.SetCacheability(HttpCacheability.NoCache)

Response.Buffer = True

Response.ExpiresAbsolute = DateTime.Now().AddDays(-1)

Response.Expires = 0

Response.CacheControl = "no-cache"

C # (C Sharp)

Response.Cache.SetCacheability(HttpCacheability.NoCache);

Response.Buffer = true;

Response.ExpiresAbsolute = DateTime.Now().AddDays(-1);

Response.Expires = 0;

Response.CacheControl = "no-cache";
