Hi,
I want to disable bacskapce (going to previous page) in radwindows.
So I added js code:

function getKey(keyStroke) {

var t = window.event.srcElement.type;

var keyCode = (document.layers) ? keyStroke.which : event.keyCode;

var keyString = String.fromCharCode(keyCode).toLowerCase();

var leftArrowKey = 37;

var backSpaceKey = 8;

var escKey = 27;

if (t && (t == 'text' || t == 'textarea' || t == 'file')) {

//do not cancel the event

} else {

if ((window.event.altKey && window.event.keyCode == leftArrowKey) || (keyCode == escKey) || (keyCode == backSpaceKey)) {

alert(keyCode);

return false;

}

}



<body onkeydown="getKey()">...

but it doesn't work (alert is showing, but "false"doesn't stop going to previous page). Is any specific approach in radwindows to achieve the target?
Thanks.

Hi, I don't remember now where I had a mistake but below I pasted my working code:

function pageLoad() {

var holder;

var element;

/* IE uses this */

if (typeof window.event != 'undefined') {

document.onkeydown = function() {

element = event.srcElement.tagName.toUpperCase();

// alert(element);

if (event.srcElement.tagName.toUpperCase() != 'INPUT' && event.srcElement.tagName.toUpperCase() != 'TEXTAREA') {

holder = event.keyCode;

// alert(holder);

return cancelBackspace(holder);

}

else {

if (event.srcElement.readOnly || event.srcElement.disabled) {

holder = event.keyCode;

return cancelBackspace(holder);

}

}



function cancelBackspace(holder) {

    if (holder == 8) {

        return false;

    }

}
