The DesignerActionService.Clear method empties the internal table used to store information about components and their push-model smart tag lists.
Because this method affects all components managed by the current service, and not just the current component, this method should be used judiciously. Typically, the design-time tool developer uses it when resetting a design surface. Component developers should use one of the erload:System.ComponentModel.Design.DesignerActionService.Remove methods instead to remove individual smart tag items or lists.
A DesignerActionService.DesignerActionListsChanged event is raised for each component that was previously managed by the current service.
