override this.OnDropDown : EventArgs -> unit
Protected Overridable Sub OnDropDown (e As EventArgs)

Parameters

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 OnDropDown 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 OnDropDown(EventArgs) in a derived class, be sure to call the base class’ OnDropDown(EventArgs) method so that registered delegates receive the event.
