Modal popup extender and multiple dropdownlists

Hi,

My requirement is that-On a panel,which acts as modal pup up extender,I have multipledropdownlists(cascading),so on selecting one,an autopostback happens,and then the modal pop up disappears.How can I handle,autopostbacksfrom modalpopup so that,the popup does not disappear.

In general, wrapping content in an UpdatePanel is the way to hide the postback of that content. ModalPopup allows UpdatePanels to be within the popup content, so that should work here, too.
