Protected Overrides Sub OnUnsubscribeControlEvents (control As Control)

Parameters

control: Control

The control from which to unsubscribe events.

Remarks

Override the OnSubscribeControlEvents method to unsubscribe events subscribed in OnSubscribeControlEvents.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnUnsubscribeControlEvents method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnUnsubscribeControlEvents(Control) in a derived class, be sure to call the base class’s OnUnsubscribeControlEvents(Control) method so that registered delegates receive the event.
