Raises the Control.LostFocus event.
- source
- The source of the event.
- e
- An EventArgs that contains the event data.
This method validates the text in the text box portion of the control when the spin box (also known as an up-down control) loses focus.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The UpDownBase.OnTextBoxLostFocus(object, EventArgs) 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.
