Control.OnLostFocus(EventArgs) Method
Definition
Raises the LostFocus event.
protected:

protected virtual void OnLostFocus (EventArgs e);
abstract member OnLostFocus : EventArgs -> unit

Protected Overridable Sub OnLostFocus (e As EventArgs)
Parameters
Remarks
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(EventArgs) in a derived class, be sure to call the base class's OnLostFocus(EventArgs) method so that registered delegates receive the event.
