Height or Width are both still available as members and are settable. The object where the Height or Width properties are set is almost always a child object in another parent's child collection, and setting Height or Width to a value is only a suggested value for the layout process.
The layout system as well as the particular layout logic of the parent's class will use the value as a nonbinding input during the layout process, and might have to clip, resize the object, resize the container, or some combination of these behaviors that spans multiple participating objects in layout. Margin and padding also influences the available size. For more info, see Alignment, margin, and padding. The return value of this property is always the same as any value that was set to it.
In contrast, the value of the ActualWidth property may vary. The variance can occur either statically, because the layout rejected the suggested size, or momentarily. The layout system itself works asynchronously relative to the property system's set of Width, and the layout system might not have processed that sizing property change yet.
