SizeChangedEventArgs.WidthChanged Property

Gets a value that indicates whether the Width component of the size changed.

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

public bool WidthChanged { get; }

Property Value

Type: System.Boolean
true if the Width component of the size changed; otherwise, false.

Because Double precision numbers process imprecisely, this property might return a value of false even when PreviousSize and NewSize are not equal.

The layout system occasionally experiences this state due to minor fluctuations in the input parameters; however, the overall rendered scene is considered to be the same; therefore, no visible changes are detected. The handler for the SizeChanged event should check for this state in order to avoid invalidation of layout if the dimension didn't actually change.
