WebPartManager.OnWebPartClosing Method

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

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

protected virtual void OnWebPartClosing(
	WebPartCancelEventArgs e
)

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.
