Assembly: System.Web (in system.web.dll)
The WebPartDescriptionCollection class is created by the various CatalogPart controls in their implementations of the GetAvailableWebPartDescriptions method. For each WebPart control that is contained in a CatalogPart control, a WebPartDescription object is created. This object maintains basic information about a WebPart control, including its ID, its title, its description, and a path to an associated icon. The various CatalogPart controls can use a WebPartDescription object to display a WebPart control's information in the catalog, without having to create an instance of the WebPart control itself.
The WebPartDescriptionCollection class is used internally by the Web Parts control set to maintain a collection of all the WebPartDescription objects used in a catalog. The WebPartDescriptionCollection collection is used only when a page is in catalog display mode. When a CatalogPart control is being rendered, it loops through the WebPartDescriptionCollection collection, adding the information from each WebPartDescription object to the displayed catalog.
