DataServiceContext.BeginSaveChanges Method (AsyncCallback, Object)

Asynchronously submits the pending changes to the data service collected by the DataServiceContext since the last time changes were saved.

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

public IAsyncResult BeginSaveChanges(
	AsyncCallback callback,
	Object state


Type: System.AsyncCallback
The delegate to call when the operation is completed.
Type: System.Object
The user-defined state object that is used to pass context data to the callback method.

Return Value

Type: System.IAsyncResult
An IAsyncResult that represents the status of the asynchronous operation.

Changes are added to the DataServiceContext by calling the AddObject, AddLink, AttachTo, AttachLink, DeleteObject, DeleteLink, Detach, or DetachLink.

Changes are sent to the data service, as with the SaveChanges method, one change operation per HTTP request.

If an error occurs while processing an operation, no additional operations are processed by the data service. Instead, a response is generated telling the client what operations were executed, the results, and which operations were not tried because of an error.
