Allows a designer to change or remove items from the set of properties that it exposes through a System.ComponentModel.TypeDescriptor.
This method provides a way to change or remove the items within the dictionary of properties that are exposed through a System.ComponentModel.TypeDescriptor.
The keys in the dictionary of properties are the names of the properties. The objects are of type System.ComponentModel.PropertyDescriptor. This method is called immediately after the ComponentDesigner.PreFilterProperties(IDictionary) method.
