Protected Overridable Sub OnKeyUp( _
   ByVal sender As Object, _
   ByVal e As KeyEventArgs _
) 

Visual Basic (Usage)	Copy Code
Dim instance As DropDownEditor Dim sender As Object Dim e As KeyEventArgs   instance.OnKeyUp(sender, e)

protected virtual void OnKeyUp( 
   object sender,
   KeyEventArgs e
)

Parameters

sender

An System.Object value that indicates the event sender.

e

The System.Windows.Forms.KeyEventArgs instance that contains the event data.

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

Target Platforms: Windows 2000 Professional (SP4), Windows 2000 Server, Windows 2003 Server (SP1), Windows 2008, Windows XP (SP2), Windows Vista, Windows 7, Windows 8
