Allows a designer to add to the set of properties that it exposes through a TypeDescriptor.
Assembly: System.Design (in System.Design.dll)
This method provides a way to add items to the dictionary of properties that a designer exposes through a TypeDescriptor.
You can directly modify the dictionary that is accessible through the properties parameter, or you can leave it unchanged. If you override this method, call the base implementation before you perform your own filtering.
