Classes

	Class	Description
	CollectionViewObject	Represents an object that resides within a RadCollectionViewSource instance.
	CurrentItemChangingEventArgs	Encapsulates the data associated with a CurrentItemChanging()()()() event.
	DataDescriptor	Base class for all descriptors that define one of the following data operations: sorting, filtering or grouping.
	DataGroup	Represents a group of items, created upon a grouping data operation.
	DataHelper	Exposes common data-related operations.
	GenericFilterDescriptor<(Of <(<'TElement>)>)>	Represents a data descriptor that defines filtering mechanism and uses a generic delegate to see whether an item meets filtering criteria.
	GenericGroupDescriptor<(Of <(<'TElement, TKey>)>)>	Represents a data descriptor that defines a grouping operation and uses generic delegates to retrieve each item's key.
	GenericKeyDataDescriptor<(Of <(<'TElement, TKey>)>)>	Base class for all descriptors that perform data operation upon certain keys and use a generic delegate to retrieve each item's key.
	GenericSortDescriptor<(Of <(<'TElement, TKey>)>)>	Represents a data descriptor that defines a sort operation and uses generic delegates to retrieve each item's key.
	PropertyDataDescriptor	Base class for all data descriptors that use a property name to extract data keys.
	PropertyGroupDescriptor	Represents a descriptor that defines a grouping data operation and uses the name of the desired property to look-up keys.
	PropertySortDescriptor	Represents a descriptor that defines a sorting data operation and uses property to retrieve the keys of each item.
	SortableDataDescriptor	Represents a DataDescriptor which has knowledge for a sort operation.
	VirtualizingDataCollection	Represents a data collection that allows for loading its data items on demand. The collection exposes events and API that notifies the user when data items at specific indexes have to be loaded and allows them to load the data into the collection when it is received.
	VirtualizingDataCollectionItemsLoadingEventArgs	Represents a class that holds information about the ItemsLoading event.

Interfaces

	Interface	Description
	ICurrencyManager	Defines a collection that adds support for tracking the current item within the collection.
	IDataSourceGroup	Represents a group view model within a collection view source.
	IDataSourceItem	Defines a data source view model, used by RadListSource.
	IDescriptorProcessor	Defines an instance that may perform data operation, using data descriptor.
	INamedDescriptor	Defines a DataDescriptor instance that is identified by a name.

Enumerations

	Enumeration	Description
	CollectionViewEnumerationMode	Defines how a RadCollectionViewSource instance may be iterated.
	CurrencyManagementMode	Specifies the mode used by a ICurrencyManager instance to update its CurrentItem property.
	DataOperationType	Defines the possible data descriptor types.
	ListSortMode	Defines the sorting mode within a SortableDataDescriptor.
