ClassRadExpander
Represents a collapsible content control that can expand and collapse to reveal or hide its content.
The RadExpander class derives from HeaderedContentControl and implements the IThemable interface.
It provides features for handling expansion and collapsing events, customizing the appearance of the header and button,
and managing the visual states corresponding to the various expansion directions.
The IsExpanded property determines whether the content is currently displayed.
The control also includes properties for various header alignments, orientations, and styles, as well as events that notify
when the content is expanded or collapsed.
