Asynchronously loads items into the collection, when it represents the navigation property of an entity.
Assembly: System.Data.Services.Client (in System.Data.Services.Client.dll)
'Declaration Public Sub LoadAsync
public void LoadAsync()
When you use the Add Service Reference dialog or the DataSvcUtil.exe tool with the /binding option to generate the client data service classes, navigation properties that return a collection are generated as instances of DataServiceCollection<T>. When an instance of DataServiceCollection<T> is obtained from such a property, the LoadAsync method is used to load the related entities from the data service into the collection.
Because the LoadAsync method is asynchronous, the method returns before a response to the data service is received. You must handle the LoadCompleted event to access the QueryOperationResponse<T> that contains information about the result of the load operation. Items are loaded into the collection when the load operation is complete, whether or not the LoadCompleted event is handled.
The LoadAsync method can be called only once on the UI thread. The method cannot be called again until after the LoadCompleted event is raised. The LoadCompleted event is raised whether or not the query succeeds.
