BaseView.KeyDown Event

Fires when a key is pressed while the View has focus.

Namespace:DevExpress.XtraGrid.Views.Base
Assembly:DevExpress.XtraGrid.v17.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type System.Windows.Forms.KeyEventArgs containing data related to this event.

The following KeyEventArgs properties provide information specific to this event.
Property Description
Alt Gets a value indicating whether the ALT key was pressed.
Control Gets a value indicating whether the CTRL key was pressed.
Handled Gets or sets a value indicating whether the event was handled.
KeyCode Gets the keyboard code for a System.Windows.Forms.Control.KeyDown or System.Windows.Forms.Control.KeyUp event.
KeyData Gets the key data for a System.Windows.Forms.Control.KeyDown or System.Windows.Forms.Control.KeyUp event.
KeyValue Gets the keyboard value for a System.Windows.Forms.Control.KeyDown or System.Windows.Forms.Control.KeyUp event.
Modifiers Gets the modifier flags for a System.Windows.Forms.Control.KeyDown or System.Windows.Forms.Control.KeyUp event. The flags indicate which combination of CTRL, SHIFT, and ALT keys was pressed.
Shift Gets a value indicating whether the SHIFT key was pressed.
SuppressKeyPress Gets or sets a value indicating whether the key event should be passed on to the underlying control.

Expanded Remarks

When pressing a key, the KeyDown event is raised. If holding the key pressed for a while, the event is raised repeatedly with a short interval. Thus, you can handle the event to implement repeated actions. However, if you do not want to perform repeated actions, you need to have a flag indicating whether the desired actions have already been performed. This flag must be reset in the KeyUp event handler. The KeyUp event is raised when the pressed key is released.

As soon as the KeyDown event has been raised, the View generates a KeyPress event if a character key is pressed. The KeyPress event is not raised for non-character keys.

If an inplace editor is active, it processes key presses. In this case, the View's key events are not raised.
