protected internal virtual void OnStyleChanged(
	Style oldStyle,
	Style newStyle
)

Parameters

oldStyle
Type: System.Windows.Style

The old style.

newStyle
Type: System.Windows.Style

The new style.

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