TypeDescriptor.Refresh Method (Module)
Clears the properties and events for the specified module from the cache.
Assembly: System (in System.dll)
Properties and events are cached by TypeDescriptor for speed. Typically, they are constant for the lifetime of an object. However, extender providers and designers can change the set of properties on an object. If they do, they can call this method to clear the property and event descriptors of the object. This method is used only at design time. It is not used during run time.
This method also raises a Refreshed event to notify all classes that want to be notified when the property set of a component changes.
