A NDiagramTechnologyFactory factory is used by the NDrawingView class to create different NDiagramClientServerTechnology instances based on a Nevron.UI.WebForm.Controls.WebControlTechnologyType control parameter. The factory, used by a NDrawingView instance is initialized once in the control's constructor. Later, when the Technology property of the NDrawingView instance is changed, the factory replaces the current NDiagramClientServerTechnology instance, exposed by the ClientServerTechnology property of the NDrawingView object with a new instance of a different NDiagramClientServerTechnology implementation.

E.g. when the Technology property is set to WebControlTechnologyType.Ajax, the ClientServerTechnology is initialized with a NDiagramAjaxTechnology instance. When the Technology property is set to WebControlTechnologyType.Postback, the ClientServerTechnology is initialized with a NDiagramPostbackTechnology instance.
