Use the BaseDockOptions.ShowAutoHideButton property to specify whether an end-user can enable/disable auto-hiding a panel at runtime. The Collapsing occurs at the very beginning of hiding a panel. After it is completely hidden, the Collapsed event occurs. The Expanding and Expanded event are opposite events, fired when a hidden auto-hide panel is shown.
