Many of the UIElement derived objects are also derived from Shape. Not all the Shape classes typically use Height or Width to specify their appearance. Instead, they use specific properties that might define a set of points. In this case, a Height or Width is calculated but not typically set directly.
TextBlock is a container object that displays text within it. The size of that text can influence the size of the rendered TextBlock. Therefore, TextBlock supports two additional properties that expose that calculated size: ActualHeight and ActualWidth.
