The FilterWebPartVerbs method provides a way to automatically filter certain verbs from the collection of verbs associated with a WebPart control, and prevent the filtered verbs from being rendered.
Notes to Inheritors:
If you create a custom WebPartChrome class, you can optionally override the FilterWebPartVerbs method to filter out specific verbs from being rendered. The most common way to do this is to create a private method that checks the verbs in the Verbs collection of a WebPart control and determines whether each verb should be rendered, based on criteria that you choose. Note that the base method provides a lot of default filtering criteria that would be difficult to reproduce if you completely override the method; if you only have a few special cases, you might want to call the base method first, and then pass the resulting collection through your own additional method to apply your custom filtering criteria.
