The ContentTemplate property is being defined when the ContentTemplateContainer property has already been created.

The UpdatePanel control's ContentTemplate property is instantiated during the OnInit method.

The OnInit method is used by control developers to extend the functionality of the UpdatePanel control.

Notes to Inheritors:

When you override the OnInit method in a derived class, make sure to call the OnInit method of the base class so that registered delegates can receive the event.
