CheckedListBox.OnKeyPress(KeyPressEventArgs) Method

Definition

Raises the KeyPress event.

protected override void OnKeyPress (System.Windows.Forms.KeyPressEventArgs e);

Parameters

e
KeyPressEventArgs

The KeyPressEventArgs that was raised.

Remarks

If the spacebar is pressed and the SelectionMode property is not set to SelectionMode.None, the OnKeyPress method switches the check state of the item currently selected.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnKeyPress 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 OnKeyPress(KeyPressEventArgs) in a derived class, be sure to call the base class' OnKeyPress(KeyPressEventArgs) method so that registered delegates receive the event.
