UpDownBase.OnTextBoxKeyDown Method (Object, KeyEventArgs)
Raises the KeyDown event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
If the InterceptArrowKeys property is set to true and the user presses the UP ARROW key, the UpButton method is called. Likewise, if the user presses the DOWN ARROW key, the DownButton method is called.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
Themethod 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 overridingin a derived class, be sure to call the base class's method so that registered delegates receive the event.
