WebPart.OnClosing Method

Enables derived classes to provide custom handling when a WebPart control is closed on a Web Parts page.

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

protected internal virtual void OnClosing(
	EventArgs e
)

Parameters

e
Type: System.EventArgs

An EventArgs that contains the event data.

The method in the WebPart base class contains no implementation. Derived WebPart controls can override the method if needed to provide custom handling when the control is closed. The WebPartManager control automatically invokes the OnClosing method if you provide an implementation in a derived class.
