}

The WebPartClosed event indicates that a control has been successfully closed, either by a user or programmatically. To close a WebPart control means to remove it from a page so that it is not rendered, and also to place it in a special holding object called a page catalog. A page catalog, which corresponds to the PageCatalogPart control, maintains references to closed WebPart controls for each page. If a PageCatalogPart control is declared on a page within a CatalogZone zone, users can switch a page into catalog display mode, and add back to a page any controls that were previously closed.

The WebPartClosed event is associated with the OnWebPartClosed method, which both raises the event and provides a handler for it.

Page developers can add a custom handler for the event by adding an OnWebPartClosed attribute to the <asp:webpartmanager> element in a page, and then assigning a custom method name to the attribute.
