FrameworkElement.OnStyleChanged Method

Invoked when the style in use on this element changes, which will invalidate the layout.

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

protected internal virtual void OnStyleChanged (
	Style oldStyle,
	Style newStyle
)
protected void OnStyleChanged (
	Style oldStyle, 
	Style newStyle
)
protected internal function OnStyleChanged (
	oldStyle : Style, 
	newStyle : Style
)
You cannot use methods in XAML.

Parameters

oldStyle

The old style.

newStyle

The new style.

This method has a default implementation that sets an internal flag that notes the style changed condition.

Notes to Inheritors: You should not typically have to override this method. Any change to a style that involves a measure or arrange change would already trigger another render cycle, assuming a typical implementation of ArrangeOverride / MeasureOverride, or the defaults. Overrides of OnStyleChanged might be appropriate if your ArrangeOverride / MeasureOverride implementations were deliberately optimizing or supporting partial updates, but still wanted to apply changes to styles more directly. (The partial updates would be an attempt to avoid multiple incremental calls to Measure and Arrange on any child elements).
