any ideas? ive tried using javascript to catch the event and strip out
the \n's and \r's but  onkeydown, onkeyup and onchange dont capture
the event when you past into it
 

onchange fires only after the text box looses focus. What you need to do 
is check the the text box while it has focus. A combination of onkeyup 
and onmousemove might work, but I haven't tested it. It would likely 
have the disadvantage of not making the change until after the user 
leaves the field, which could be confusing. A possible solution it 
polling while the text box has focus using setInterval. How often to 
poll is a judgment call; below I used 50 milliseconds, or 1/20 of a second.

var txtbox;
var intr;
var txt;
function setUp() {
  txtbox=document.getElementById("txtboxid");
  txtbox.onfocus = function(){txt=this;intr = 
setInterval("checkTextBox(txt)",50);};
  txtbox.onblur = function() {clearInterval(intr);};
 
}

window.onload = setUp;
