Control.OnKeyPress Method (KeyPressEventArgs)

 

Raises the KeyPress event.

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

abstract OnKeyPress : 
        e:KeyPressEventArgs -> unit
override OnKeyPress : 
        e:KeyPressEventArgs -> unit

Parameters

e
Type: System.Windows.Forms.KeyPressEventArgs

A KeyPressEventArgs that contains the event data.

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.

The following code example uses the KeyPress event to prevent characters from entering the control.
