How to disable Browser Back button in asp.net application

Jul 18 2012 1:23 AM
Hi, Recently i got a requirement, to disable browser back button through out application. I tried with different ways like

 function disableBackButton() { window.history.forward() }
        disableBackButton();
        window.onload = disableBackButton;
        window.onpageshow = function(evt) { if (evt.persisted) disableBackButton() }
        window.onunload = function() { void (0) }

I put the above code in master page, but in some scenario this is not working fine, and more over when i click browser back button page is loading.


After then I tried with following code.  Put the follwoing code in Master page Header section.

<script type="text/javascript">

function changeHashOnLoad() {
            window.location.href += "#";
            setTimeout("changeHashAgain()", "50");
        }
        function changeHashAgain() {
            window.location.href += "1";
        }
        var storedHash = window.location.hash;
        window.setInterval(function() {
        if (window.location.hash != storedHash)
        { window.location.hash = storedHash; } }, 50);

</script> 

<body onload ="changeHashOnLoad();">



Using the above code the browser back button will not work in all browsers and page loading also avoided.. I hope itwill work fine.
