UpDownBase.OnTextBoxKeyPress Method

Raises the KeyPress event.

[Visual Basic]
Protected Overridable Sub OnTextBoxKeyPress( _
   ByVal source As Object, _
   ByVal e As KeyPressEventArgs _
protected virtual void OnTextBoxKeyPress(
 object source,
 KeyPressEventArgs e
protected: virtual void OnTextBoxKeyPress(
 Object* source,
 KeyPressEventArgs* e
protected function OnTextBoxKeyPress(
   source : Object,
 e : KeyPressEventArgs


The source of the event.
A KeyPressEventArgs that contains the event data.


Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

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