Clears the properties and events for the specified component from the cache.
public:
static void Refresh(System::Object ^ component);public static void Refresh (object component);static member Refresh : obj -> unitPublic Shared Sub Refresh (component As Object)Parameters
- component
- Object
A component for which the properties or events have changed.
Examples
For an example of using this method, see the RefreshEventHandler class.
Remarks
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 should 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 when the properties or events of a component change. This event is only raised if there was a prior call to the GetProperties or GetEvents method that cached the information.

This method also raises a Refreshed event to notify all classes that want to be notified when the property set of a component changes.
