asp.net ajax popupextender aligment issue

I have used the ajax popup in my application where one link opens a popup and from the popup, there is another popupextender that gets opened. This popup is not center aligned. Is there any way i c开发者_运维百科an align this popup to the center of the screen. Note that the first popup is center aligned but second one is not.

are you hiding the first popup when showing another one?, if not, use client side scripts to do so and i think that will solve your problem.

you can see good example here - http://beta.firstphera.com/GiftRegistry/ProductDetails.aspx?pcid=23

just click on any product image, enter quantity and click on add to registry
