Part Manager. Web Part Closed Event
Occurs when a WebPart control (or server or user control) is removed from a page.
public: event System::Web::UI::WebControls::WebParts::WebPartEventHandler ^ WebPartClosed;
public event System.Web.UI.WebControls.WebParts.WebPartEventHandler WebPartClosed;
member this.WebPartClosed : System.Web.UI.WebControls.WebParts.WebPartEventHandler
Public Custom Event WebPartClosed As WebPartEventHandler
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.
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.
