ClassRadExpanderAutomationPeer
Represents the automation peer for a RadExpander control, enabling UI automation support for the control's expand and collapse functionality. This class inherits from FrameworkElementAutomationPeer and implements the IExpandCollapseProvider interface. It provides functionality to determine the expanded or collapsed state of the control, as well as methods to expand and collapse the content. The class also supports retrieving the associated control patterns, automation control type, and details about the control such as its name and properties. It ensures that operations can only be performed on an enabled instance of RadExpander and raises appropriate automation events when the expand/collapse state changes.
