I am trying to place a <code>Popup</code> element in a specific position, relative to the <code>Placement</code> control. In order to achieve that I need to find out the <code>ActualWidth</code> of the popup control. But trying to get this value before or after displaying the popup (IsOpen = True) it always returns 0. Unfortunately I cannot hard code the size of the popup. How can I determine the <code>ActualWidth</code>?

Have you tried getting the <code>ActualWidth</code> of the popup's child element?
