DataServiceCollection(Of T) Constructor (IEnumerable(Of T), TrackingMode)

Creates a new instance of the DataServiceCollection(Of T) class based on query execution and with the specified tracking mode.

Namespace:  System.Data.Services.Client
Assembly:  System.Data.Services.Client (in System.Data.Services.Client.dll)

Public Sub New ( _
	items As IEnumerable(Of T), _
	trackingMode As TrackingMode _


Type: System.Collections.Generic.IEnumerable(Of T)
A DataServiceQuery(Of TElement) or LINQ query that returns an IEnumerable(Of T) collection of objects that are used to initialize the collection.
Type: System.Data.Services.Client.TrackingMode
A TrackingMode value that indicated whether or not changes made to items in the collection are automatically tracked.

By default, automatic change tracking is enabled for a DataServiceCollection(Of T). Use this class constructor and supply a value of None for trackingMode to create an instance of DataServiceCollection(Of T) that uses manual change tracking. When you use manual tracking, you must implement INotifyPropertyChanged and INotifyCollectionChanged and handle the raise events to manually report changes to the DataServiceContext.

The IEnumerable(Of T) collection of objects supplied for items is usually a query that returns the items in the collection. However, any IEnumerable(Of T) collection of the correct type can be supplied.
