How do I disable Back button on the browser?

Question

I would like to disable the back button on the browser. I have done it before using this code on the page load, but for some reason it is not working anymore.

Response.Cache.SetCacheability(HttpCacheability.NoCache)

the application that I am running it is actually running as an iFrame for a second application, I wondering if this is the reason my code it is not working.

Note that there are some people that will be very frustrated by applications that do that. You might need to partially go back within your application but totally disabling the ability to go back even to the pages prior to your application can be frustrating. If you could hear them you would know that many people are not happy when they can't go back. The whole system of HTTP and HTML and ASP is not well-designed and the history of navigations is a victom of that. In other words history often does not work correctly in ASP applications. It is frustrating for me when applications such as Facebook cannot remember where I have been. I really depend on navigation history to get me back to where I have been. Sometimes it is highly inconvenient to somehow get back to where I have been when the history does not work.

I sort of work just like function disableBackButton() { window.history.forward(); } setTimeout(disableBackButton() 0); What I was actually looking for was to be able to remove the history cache so it would gray out the back button.

this might helps you.. protected override void OnPreRender(EventArgs e) { base.OnPreRender(e); string strDisAbleBackButton; strDisAbleBackButton =  
; strDisAbleBackButton += window.history.forward(1);
; strDisAbleBackButton += 
 ; ClientScript.RegisterClientScriptBlock(this.Page.GetType() clientScript strDisAbleBackButton); }
