public virtual ConnectionInterfaceCollection GetSecondaryInterfaces ( Control control )
public function GetSecondaryInterfaces ( control : Control ) : ConnectionInterfaceCollection
The control acting as the provider in a Web Parts connection.
Return ValueA ConnectionInterfaceCollection of additional interfaces provided by the control acting as a provider.
A provider connection point object always has a default interface that is used to establish a connection with consumers. An instance of the default interface is retrieved by calling the GetObject method on a ProviderConnectionPoint object.
However, some provider controls will implement multiple interfaces to provide to consumers as part of a connection. These interfaces, which are not the default ones used to establish a connection, are called secondary interfaces. The GetSecondaryInterfaces method provides a way to return a collection of references to the secondary interfaces, just as the GetObject method returns a reference to the default interface.Notes to Inheritors The GetSecondaryInterfaces method in the ProviderConnectionPoint class contains no implementation; it returns an empty collection of secondary interfaces. To implement this method, you must inherit from the ProviderConnectionPoint class, and override this method, returning from it a specific set of secondary interfaces.
