Not all of the Shape classes typically use Height or Width to specify their appearance, and instead use specific properties that might define a set of points. In this case a Height or Width is calculated, but is not typically set directly. See Shapes and Drawing. Custom classes might have similar considerations where the class might have properties that are more meaningful for specifying dimensions than are Height or Width.

In this case Height or Width will both still be available as members and are settable, even though the desirable behavior might be to not enable Height or Width setting. In critical cases, it might be worth shadowing the Height and Width properties to prevent them from being set directly by consumers of the class. TextBlock is an example of a container object, where the container displays text within it. The size of that text can influence the size of the rendered TextBlock ; therefore, TextBlock might not be honoring the specified Height or Width.

For container objects such as TextBlock , you should check two additional properties that expose that calculated size, ActualHeight and ActualWidth. Negative values for Width are not permitted. Non-integral values for Width are technically permitted. Values are preserved as non-integral values if set that way in XAML or code, but should generally be avoided and are normally rounded by the default layout rounding behavior.

See Layout Rounding. In addition to the validation check, there is a nondeterministic upper value bound for Width this is a very large number, larger than Single. MaxValue but smaller than Double. Do not set Width to a value that is significantly larger than the maximum size of any possible visual display, or you may exceed this nondeterministic upper bound. The default value of Height and Width is not 0; it is Double.
