RowDefinition.ActualHeight Property

Gets a value that represents the calculated height of the RowDefinition.

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

public double ActualHeight { get; }

Property Value

Type: System.Double
A Double that represents the calculated height in device independent pixels. The default value is 0.0.

When you use these values in the same code example, the MinHeight value takes precedence over the MaxHeight value, which in turn takes precedence over the Height value.

When you add or remove rows or columns, the ActualWidth for all ColumnDefinition elements and the ActualHeight of all RowDefinition elements becomes zero until Measure is called.
