DesignerEventHandler Delegate
.NET Framework (current version)
Represents the method that will handle the DesignerCreated and DesignerDisposed events that are raised when a document is created or disposed of.
Assembly: System (in System.dll)
[HostProtectionAttribute(SecurityAction::LinkDemand, SharedState = true)] public delegate void DesignerEventHandler( Object^ sender, DesignerEventArgs^ e )
Parameters
- sender
-
Type:
System::Object^
The source of the event.
- e
-
Type:
System.ComponentModel.Design::DesignerEventArgs^
A DesignerEventArgs that contains the event data.
When you create a DesignerEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see NIB: Events and Delegates.
The following example demonstrates registering a DesignerEventHandler and handling the DesignerCreated and DesignerDisposed events.
public: void LinkDesignerEvent( IDesignerEventService^ eventService ) { // Registers an event handler for the DesignerCreated and DesignerDisposed events. eventService->DesignerCreated += gcnew DesignerEventHandler( this, &DesignerEventHandlerExample::OnDesignerEvent ); eventService->DesignerDisposed += gcnew DesignerEventHandler( this, &DesignerEventHandlerExample::OnDesignerEvent ); } private: void OnDesignerEvent( Object^ sender, DesignerEventArgs^ e ) { // Displays designer event information on the console. Console::WriteLine( "Name of the root component of the created or disposed designer: " + e->Designer->RootComponentClassName ); }
