OnValidating Method (EditBase)

Raises the System.Windows.Forms.Control.Validating event.

Syntax

Visual Basic
C#

'Declaration
 
Protected Overrides Sub OnValidating( _
   ByVal e As CancelEventArgs _
)

'Usage
 
Dim instance As EditBase
Dim e As CancelEventArgs
 
instance.OnValidating(e)

protected override void OnValidating( 
   CancelEventArgs e
)

Parameters

e: A System.ComponentModel.CancelEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate.

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

Requirements

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