Part. On Deleting(EventArgs) Method
Enables derived classes to provide custom handling when a WebPart control is permanently removed from a Web Parts page.
protected public: virtual void OnDeleting(EventArgs ^ e);
protected internal virtual void OnDeleting (EventArgs e);
abstract member OnDeleting : EventArgs -> unit override this.OnDeleting : EventArgs -> unit
Protected Friend Overridable Sub OnDeleting (e As EventArgs)
The method in the WebPart base class contains no implementation.
Notes to Inheritors
A derived control needs to override the OnDeleting(EventArgs) method. Developers can raise custom events or carry out other actions. The method is called when the DeleteWebPart(WebPart) method is called.
