A ToolboxComponentsCreatingEventArgs that provides data for the event.
Remarks
The OnComponentsCreating method raises the ComponentsCreating event. This method is called after a toolbox item is invoked to create components, just before the CreateComponentsCore method is called.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnComponentsCreating 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 OnComponentsCreating(ToolboxComponentsCreatingEventArgs) in a derived class, be sure to call the base class' OnComponentsCreating(ToolboxComponentsCreatingEventArgs) method so that registered delegates receive the event.
