Answer 1

It sounds like the $find call is probably not finding the behavior. Can you change the code to:

var behavior = $find('ModalPopupExtender1');
var undefined;
if (behavior !== undefined)
   alert("found");
else
   alert("not found");

Answer 2

There are 2 options to solve this:

1)Change/add a behaviorID to the modalpopup and name it ("ModalPopupExtender1")

2)Change your script to this:

$find('<%= ModalPopupExtender1.ClientID%>').hide();
