-/**
- * TMultiView class
- *
- * TMultiView serves as a container for a group of {@link TView} controls.
- * The view collection can be retrieved by {@link getViews Views}.
- * Each view contains child controls. TMultiView determines which view and its
- * child controls are visible. At any time, at most one view is visible (called
- * active). To make a view active, set {@link setActiveView ActiveView} or
- * {@link setActiveViewIndex ActiveViewIndex}.
- *
- * TMultiView also responds to specific command events raised from button controls
- * contained in current active view. A command event with name 'NextView'
- * will cause TMultiView to make the next available view active.
- * Other command names recognized by TMultiView include
- * - PreviousView : switch to previous view
- * - SwitchViewID : switch to a view by its ID path
- * - SwitchViewIndex : switch to a view by its index in the {@link getViews Views} collection.
- *
- * TMultiView raises {@link OnActiveViewChanged OnActiveViewChanged} event
- * when its active view is changed during a postback.
