CheckedListBox::OnKeyPress Method (KeyPressEventArgs^)

 

Raises the KeyPress event.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

protected:
virtual void OnKeyPress(
	KeyPressEventArgs^ e
) override

Parameters

e
Type: System.Windows.Forms::KeyPressEventArgs^

The KeyPressEventArgs that was raised.

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 in a derived class, be sure to call the base class’s OnKeyPress method so that registered delegates receive the event.
