Hi Faleh,
I regret for the delayed response.
It is not possible to align the waiting popup to show in middle - top which the CallbackPanel uses. But you can use a separate WaitingPopup control to show the control in Middle.
Please refer to our shipped browser sample to get more details and it is available in the below location:
