I am trying to place a popup element in a specific position, relative to the Placement control.
In order to achieve that i need to find out the actual width of the popup control. But trying to get this value before or after displaying the popup (IsOpen = True) it always returns 0.
Anybody got a clue?
(I know Things would be ok if i could just hard code the size of the popup, but unfortunately i cant do so in this case)
