Assembly: PresentationFramework (in presentationframework.dll)
The old style.
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).
