The first time the ComponentEditorForm.OnActivated(EventArgs) method is executed, it shows the first component editor page in the list.

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

The ComponentEditorForm.OnActivated(EventArgs) 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.
