DataServiceCollection<T> Class

Represents a dynamic entity collection that provides notifications when items get added, removed, or when the list is refreshed.

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

public class DataServiceCollection<T> : ObservableCollection<T>

Type Parameters

T

An entity type.

The DataServiceCollection<T> type exposes the following members.

  NameDescription
Public methodDataServiceCollection<T>()Creates a new instance of the DataServiceCollection<T> class with automatic change tracking enabled.
Public methodDataServiceCollection<T>(DataServiceContext)Creates a new instance of the DataServiceCollection<T> class that uses the specified DataServiceContext.
Public methodDataServiceCollection<T>(IEnumerable<T>)Creates a new instance of the DataServiceCollection<T> class based on query execution.
Public methodDataServiceCollection<T>(IEnumerable<T>, TrackingMode)Creates a new instance of the DataServiceCollection<T> class based on query execution and with the specified tracking mode.
Public methodDataServiceCollection<T>(DataServiceContext, String, Func<EntityChangedParams, Boolean>, Func<EntityCollectionChangedParams, Boolean>)Creates a new instance of the DataServiceCollection<T> class with the supplied change method delegates and that uses the specified DataServiceContext.
Public methodDataServiceCollection<T>(IEnumerable<T>, TrackingMode, String, Func<EntityChangedParams, Boolean>, Func<EntityCollectionChangedParams, Boolean>)Creates a new instance of the DataServiceCollection<T> class a based on query execution and with the supplied change method delegates.
Public methodDataServiceCollection<T>(DataServiceContext, IEnumerable<T>, TrackingMode, String, Func<EntityChangedParams, Boolean>, Func<EntityCollectionChangedParams, Boolean>)Creates a new instance of the DataServiceCollection<T> class a based on query execution, with the supplied change method delegates, and that uses the supplied DataServiceContext.

WCF Data Services provides the DataServiceCollection<T> class to support binding data to Silverlight controls. This class inherits from the ObservableCollection<T> class, which implements the INotifyCollectionChanged interface and is the primary data binding mechanism for Silverlight-based applications.

You can load an ObservableCollection<T> binding collection by using any collection that implements the IEnumerable<T> interface. Items loaded into the binding collection must implement the INotifyPropertyChanged interface.

Silverlight

Supported in: 5, 4

For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
