Raises the KeyDown event.

override void OnKeyDown(System::Windows::Forms::KeyEventArgs ^ e);protected override void OnKeyDown (System.Windows.Forms.KeyEventArgs e);override this.OnKeyDown : System.Windows.Forms.KeyEventArgs -> unitProtected Overrides Sub OnKeyDown (e As KeyEventArgs)Parameters
A KeyEventArgs that contains the event data.
Remarks
By default, the OnKeyDown event handler allows the user to move the splitter down when the DOWN arrow key is pressed. The OnKeyDown event handler also draws the SplitterRectangle to show the current position of the splitter while it is moving.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnKeyDown 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 OnKeyDown(KeyEventArgs) in a derived class, be sure to call the base class's OnKeyDown(KeyEventArgs) method so that registered delegates receive the event.
