Closes a selected WebPart control in a zone.
Assembly: System.Web (in System.Web.dll)
The typical way for an end user to close a WebPart control is by clicking the close verb in the control's title bar. The method calls the CloseWebPart method on the WebPartManager class, which carries out the action of closing the control. The method should only be used by derived WebPartZoneBase zones such as WebPartZone.
A closed WebPart control is not rendered on a page. Instead, it is added to the page catalog, which maintains a list of all closed controls on a page. If a Web Parts page on which a user closes a control also has an <asp:PageCatalogPart> element declared with a CatalogZone, then the user can switch the page into catalog display mode, and add the closed control back to the page.
