Raises the VisibleChanged event.

override this.OnVisibleChanged : EventArgs -> unit

Protected Overridable Sub OnVisibleChanged (e As EventArgs)

Parameters

e

EventArgs

An EventArgs that contains the event data.

Remarks

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

The OnVisibleChanged 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 OnVisibleChanged(EventArgs) in a derived class, be sure to call the base class's OnVisibleChanged(EventArgs) method so that registered delegates receive the event.
