Raises the DropDownClosed event.

protected public:
 virtual void OnDropDownClosed(EventArgs ^ e);

protected internal virtual void OnDropDownClosed(EventArgs e);

abstract member OnDropDownClosed : EventArgs -> unit
override this.OnDropDownClosed : EventArgs -> unit

Protected Friend Overridable Sub OnDropDownClosed (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 OnDropDownClosed 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 OnDropDownClosed(EventArgs) in a derived class, be sure to call the base class' OnDropDownClosed(EventArgs) method so that registered delegates receive the event.
