Overrides the base property to prevent a value from being assigned.
Assembly: System.Web (in System.Web.dll)
The property overrides the base property to prevent a value from being assigned to it, which has the effect of preventing skins from being used with the ProxyWebPartManager control. This is done because the control never exposes a user interface (UI) on a page. The same behavior is implemented by the WebPartManager control for its WebPartManager.SkinID property.
