Remarks

The TimeIntervalCollection represents a collection of TimeInterval objects. The properties and methods declared by this class can be used to perform common collection operations such as adding new or deleting existing items. Individual items can be accessed using indexer notation.

The TimeIntervalCollection class also serves as a base for the collections that contain time intervals of different types.

An instance of the TimeIntervalCollection class can be accessed via the SchedulerViewBase.VisibleIntervals property of the View object.

The following code snippets (auto-collected from DevExpress Examples) contain references to the TimeIntervalCollection class.
