WebPartManager.OnWebPartDeleting Método

Raises the WebPartDeleting event, which indicates that a dynamic WebPart control (or server or user control that is contained in a WebPartZoneBase zone) is in the process of being deleted.

Namespace:  System.Web.UI.WebControls.WebParts
Assembly:  System.Web (em System.Web. dll)

protected virtual void OnWebPartDeleting(
	WebPartCancelEventArgs e
)

Only dynamic WebPart controls can be deleted, and when a control is deleted, the control instance is permanently removed from a page and cannot be restored.Dynamic WebPart controls are those that are added programmatically, or from a Web Parts catalog, as opposed to static controls that are declared in the markup of a Web page.

The OnWebPartDeleting method raises the WebPartDeleting event to indicate that a control is being permanently deleted from its zone.O método também fornece a oportunidade para cancelar o Exclusão do processo.If the control is successfully deleted from the page, the WebPartDeleted event follows.

Page developers can provide a custom handler for the associated event by adding the OnWebPartDeleting attribute to the <asp:webpartmanager> element on a Web page, and then assigning a custom method name to the attribute.

OBSERVAÇÕES PARA Inheritors:

Developers who create derived WebPartManager classes can override the OnWebPartDeleting method to customize the event handling.
