OnTextChanging Method (EditBase)

Raises the TextChanging event.

Syntax

Visual Basic
C#

'Declaration
 
Protected Overridable Sub OnTextChanging( _
   ByVal e As TextChangingEventArgs _
)

'Usage
 
Dim instance As EditBase
Dim e As TextChangingEventArgs
 
instance.OnTextChanging(e)

protected virtual void OnTextChanging( 
   TextChangingEventArgs e
)

Parameters

e: The TextChangingEventArgs instance that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate.

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