WebPartManager.OnWebPartClosing(WebPartCancelEventArgs) Method

Definition

Raises the WebPartClosing event, which occurs during the process of a WebPart or server control being removed from a page.

C#
protected virtual void OnWebPartClosing(System.Web.UI.WebControls.WebParts.WebPartCancelEventArgs e);

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.
