Basically sometimes I need to show a form that is pre-populated with a record. Depending on the users privileges, he may or may not be able to edit the data.

The problem I’m encountering is that sometimes a user will try to edit a textbox that’s been disabled by clicking on it and hitting the “backspace” button to edit the text. This causes the browser to go back one page… Annoying.

    If it’s asp .net you can simply do it like this:

    <script language=javascript>   

    function cancelBack()   
    {   
        if ((event.keyCode == 8 ||    
           (event.keyCode == 37 && event.altKey) ||    
           (event.keyCode == 39 && event.altKey))   
            &&    
           (event.srcElement.form == null || event.srcElement.isTextEdit == false)   
          )   
        {   
            event.cancelBubble = true;   
            event.returnValue = false;   
        }   
    }   

</script>   
<body onkeydown=cancelBack()>
