How do I prevent AutoPostBack from closing the ModalPopupExtender Panel?

I placed a Formview inside a Panel inside an UpdatePanel. A Button triggers the ModalPopupExtender which displays the formview. I can change and update any field on the form. CalendarExtenders work just fine, too. But when I try to do something fancy like programmatically change the DueDate and OverDueDate fields, the formview closes and returns to the calling page.

How can I call my class methods without closing the modal popup panel?

Thanks for any thoughts or ideas.

The problem was the position of the UpdatePanel.
UpdatePanel
       Panel
           Formview

Move the UpdatePanel inside the Panel and it performs partial page refreshes correctly.
Panel
     UpdatePanel
