Cross Page Postback doesn't work for client-side enabled button
<p>I am using a cross page postback for Page A to pass data to Page B.</p>

<p>The button that causes the postback has its postbackurl set but is disabled until the user selects a value from a DDL at which point the button is enable using javascript. However this prevents the cross page postback from occurring, Page A just postbacks to itself.</p>

<p>If the button is never disabled it works fine. Anyone know how to solve this?</p>
