ComboBox::OnDropDownStyleChanged Method

Raises the DropDownStyleChanged event.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

protected:
virtual void OnDropDownStyleChanged(
	EventArgs^ e
)

Parameters

e
Type: System::EventArgs

An EventArgs that contains the event data.

This event is raised when you set DropDownStyle to a new value.

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

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