OnValidating Method (EditBase)


GrapeCity.Win.PluginInputMan Assembly > GrapeCity.Win.Spread.InputMan.CellType Namespace > EditBase Class : OnValidating Method
A System.ComponentModel.CancelEventArgs that contains the event data.
Raises the System.Windows.Forms.Control.Validating event.
Syntax
'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.
