Note: This class is new in the .NET Framework version 2.0.
Provides design-time support in a visual designer for a control where the design surface must use a preview of the associated control.
Namespace: System.Web.UI.Design.WebControls Assembly: System.Design (in system.design.dll)
Notes to Inheritors
The only distinction between the PreviewControlDesigner class and the ControlDesigner class is that the design host always displays a preview of the control and any modifications that are made in Design view are applied only to the preview of the control. Your code must specifically persist changes to the control.
