How to specify javascript to run when ModalPopupExtender is shown

Detection score: 4.0

<p>I know this is an old post but I've been trying for hours trying to get  the add_shown event to fire for a popup extender in an update panel.  Primarily trying to set the add_shown event using the pageLoad function in JavaScript.  The add_shown event wouldn't fire no matter what I did.   Nothing worked until I added the script action example given by John Ward.  Now I can set focus to my controls.  Thank you John!</p>
