WebPartCancelEventHandler Delegate

Note: This delegate is new in the .NET Framework version 2.0.

Represents the method that will handle the SelectedWebPartChanging event, WebPartClosing event, or WebPartDeleting event of the WebPartManager class.

Namespace: System.Web.UI.WebControls.WebParts
Assembly: System.Web (in system.web.dll)

public delegate void WebPartCancelEventHandler (
	Object sender,
	WebPartCancelEventArgs e
)
/** @delegate */
public delegate void WebPartCancelEventHandler (
	Object sender, 
	WebPartCancelEventArgs e
)
JScript supports the use of delegates, but not the declaration of new ones.

Parameters

sender

The source of the event.

e

A WebPartCancelEventArgs that contains the event data.

The method specified in the WebPartCancelEventHandler delegate is called when a SelectedWebPartChanging event, WebPartClosing event, or 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 on programmatically assigning an event handler, see How to: Connect Event Handler Methods to Events.
