Represents a method that will handle operations that asynchronously retrieve objects from a data store.
A list of retrieved objects.
A Exception object containing the exception information related to an operation that asynchronously retrieved the objects.
When creating a AsyncSelectDataCallback delegate, you identify a method that will handle corresponding events. To associate an event with your event handler, add a delegate instance to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information on event handler delegates, see Events and Delegates in MSDN.
