OnLostFocus Method

NumericUpDown.OnLostFocus Method (EventArgs)


Raises the LostFocus event.

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

protected override void OnLostFocus(
	EventArgs e


Type: System.EventArgs

An EventArgs that contains the event data.

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

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