MenuCommandService::OnCommandsChanged Method (MenuCommandsChangedEventArgs^)

.NET Framework (current version)

Namespace: System.ComponentModel.Design
Assembly: System.Design (in System.Design.dll)

Syntax

protected:
virtual void OnCommandsChanged(
	MenuCommandsChangedEventArgs^ e
)

Parameters

e: Type: System.ComponentModel.Design::MenuCommandsChangedEventArgs^
A MenuCommandsChangedEventArgs that contains the event data.

Remarks

The OnCommandsChanged method is called by a menu command when its status has changed.

Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.

The OnCommandsChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors:

When overriding OnCommandsChanged in a derived class, be sure to call the base class’s OnCommandsChanged method so that registered delegates receive the event.
