## Remarks  
 The method specified in the <xref:System.Web.UI.WebControls.WebParts.WebPartCancelEventHandler> delegate is called when a <xref:System.Web.UI.WebControls.WebParts.WebPartManager.SelectedWebPartChanging> event, <xref:System.Web.UI.WebControls.WebParts.WebPartManager.WebPartClosing> event, or <xref:System.Web.UI.WebControls.WebParts.WebPartManager.WebPartDeleting> event is raised.  
  
 Page developers can provide custom handlers for Web Parts events by adding an `OnSelectedWebPartChanging` attribute, `OnWebPartClosing` attribute, or `OnWebPartDeleting` attribute to the `<asp:webpartmanager>` element in a page, and assigning a custom method name to the attribute. A custom handler can also be assigned programmatically. For more information about how to subscribe to an event, see [How to: Raise and Consume Events](/dotnet/standard/events/how-to-raise-and-consume-events).
