ModalPopup + UpdatePanel + UpdateProgress

I have an operation that takes about 1min to complete. I like the updatepanel and updateprogress controls but I would like to incorporate these with a modalpop. I would like the popup to contain the updateprogress control. I tried to implement this but it does not work. Has anyone tried to do something like this?I still have the same Problem. I want to user a ModalPopup in combination with UpdateProgressTemplate. Is there any possibility to goin' like that?
