Valeur de la propriétéA horizontal alignment setting, as a value of the enumeration. The default is Stretch.
When Height and Width properties are explicitly set on an element, these measurements take higher precedent during layout and will cancel the typical effects of setting HorizontalAlignment to Stretch.
HorizontalAlignment is the Microsoft .NET property accessor for what is in reality a dependency property. This particular dependency property quite frequently has its apparent "default" value set differently in subclassed elements, particularly controls. This generally occurs in one of two ways: the dependency property is re-registered to a particular subclass, but with different metadata for setting its defaults; or there is a default style being applied that sets that dependency property value differently. For example, the apparent "default" of HorizontalAlignment for a Label control will be Left, even though Label inherits HorizontalAlignment direct from FrameworkElement. This is because that value was reset within the default style of Label, within the style's control template.
Canvas does not use HorizontalAlignment when composing layout, because Canvas is based on absolute positioning.
When inherited by Label or derived classes, Label redefines the default value of this dependency property to be Left.
