Raises the WebPartClosing event, which occurs during the process of a WebPart or server control being removed from a page.
Assembly: System.Web (in System.Web.dll)
Parameters

Type:
System.Web.UI.WebControls.WebParts::WebPartCancelEventArgs^
A WebPartCancelEventArgs that contains the event data.
The OnWebPartClosing method raises the WebPartClosing event to indicate that a control is in the process of being closed or removed from a page. The method also provides the option to cancel the closing process. If the control is successfully removed from the page, the WebPartClosed event follows.
Page developers can provide a custom handler for the associated event by adding the OnWebPartClosinging attribute to the <asp:webpartmanager> element on a Web page, and then assigning a custom method name to the attribute.
Notes to Inheritors:
Developers who create derived WebPartManager classes can override the OnWebPartClosing method to customize the event handling.
