Using keyboard events (Windows Forms .NET)
Most Windows Forms programs process keyboard input by handling the keyboard events. This article provides an overview of the keyboard events, including details on when to use each event and the data that is supplied for each event. For more information about events in general, see Events overview (Windows Forms .NET).

Keyboard events
Windows Forms provides two events that occur when a user presses a keyboard key and one event when a user releases a keyboard key:
- The xref:System.Windows.Forms.Control.KeyDown event occurs once.
- The xref:System.Windows.Forms.Control.KeyPress event, which can occur multiple times when a user holds down the same key.
- The xref:System.Windows.Forms.Control.KeyUp event occurs once when a user releases a key.
When a user presses a key, Windows Forms determines which event to raise based on whether the keyboard message specifies a character key or a physical key. For more information about character and physical keys, see Keyboard overview, keyboard events.
The following table describes the three keyboard events.
| Keyboard event | Description | Results |
|---|---|---|
| xref:System.Windows.Forms.Control.KeyDown | This event is raised when a user presses a physical key. | The handler for xref:System.Windows.Forms.Control.KeyDown receives:
|
| xref:System.Windows.Forms.Control.KeyPress | This event is raised when the key or keys pressed result in a character. For example, a user presses SHIFT and the lowercase "a" keys, which result in a capital letter "A" character. | xref:System.Windows.Forms.Control.KeyPress is raised after xref:System.Windows.Forms.Control.KeyDown.
|
| xref:System.Windows.Forms.Control.KeyUp | This event is raised when a user releases a physical key. | The handler for xref:System.Windows.Forms.Control.KeyUp receives:
