Protected Overridable Sub OnWebPartClosing (e As WebPartCancelEventArgs)

Parameters

e: WebPartCancelEventArgs

A WebPartCancelEventArgs that contains the event data.

Remarks

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 OnWebPartClosing 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(WebPartCancelEventArgs) method to customize the event handling.
