Assembly: System.Web (in system.web.dll)
A WebPartManager control uses a TransformerTypeCollection collection to keep a list of available WebPartTransformer objects on a page, whereas a ConnectionsZone object uses a TransformerTypeCollection collection to track the available WebPartTransformer objects that it contains.
Although the TransformerTypeCollection collection is read-only, you can make programmatic changes to the properties of the underlying controls referenced in the collection.
