FrameworkElement.ActualHeight Property

Namespace:  System.Windows
Assembly:  PresentationFramework (in PresentationFramework.dll)

member ActualHeight : float with get

Property Value

Type: System.Double
The element's height, as a value in device-independent units (1/96th inch per unit). The default value is 0 (zero).

Identifier field

ActualHeightProperty

Metadata properties set to true

None

This property is a calculated value based on other height inputs, and the layout system. The value is set by the layout system itself, based on an actual rendering pass, and may therefore lag slightly behind the set value of properties such as Height that are the basis of the input change.

Because ActualHeight is a calculated value, you should be aware that there could be multiple or incremental reported changes to it as a result of various operations by the layout system. The layout system may be calculating required measure space for child elements, constraints by the parent element, and so on.

Although you cannot set this property from XAML, you can base a Trigger upon its value in a style.

The following example displays various height properties.
