Calling this method causes an AsyncOperationCanceledException to be thrown, which is caught and propagated to listeners via the DataSourceError event.
Canceling an asynchronous update does not reverse the change to the data source; upon the next operation that triggers an update, the change for which the update was canceled is applied as well.
Operations for which an update was canceled are not recorded as PendingChanges.
In the case where the UpdateAsync method is canceled, any remaining uncommitted pending changes are discarded.
