WebFormsReferenceManager Class
Assembly: System.Design (in system.design.dll)
The WebFormsReferenceManager base class is implemented by designer hosts to provide access to types, directives, and user controls defined in a Web project document. A control designer class can use the WebFormsReferenceManager to access the definitions in the current document, and to add a new tag prefix to the current document.
You access the WebFormsReferenceManager services supplied by the designer host through the ReferenceManager property of a WebFormsRootDesigner implementation. The WebFormsRootDesigner implementation can be accessed in two ways:
-
Classes deriving from ControlDesigner can use the RootDesigner property to access a WebFormsRootDesigner implementation supplied by the designer host. The WebFormsReferenceManager implementation is supplied through the ReferenceManager property of RootDesigner property.
-
Other designer classes can access the WebFormsRootDesigner implementation by first obtaining the IDesignerHost services implementation through the designer component's Site, and then calling the GetDesigner method using the designer host RootComponent property.
Note: WebFormsReferenceManager replaces the obsolete interface IWebFormReferenceManager. Older designer hosts may only support the IWebFormReferenceManager interface implementation. Check that the WebFormsRootDesigner and WebFormsReferenceManager implementations supplied by the designer host are not a null reference (Nothing in Visual Basic) to ensure the designer host implements the WebFormsRootDesigner and WebFormsReferenceManager classes.
