OnTextChanged Method

Summary

Occurs when the value Text property changes.

Syntax

C#
VB
C++
protected virtual void OnTextChanged( 
   RoutedPropertyChangedEventArgs<string> e 
) 
  
Protected Overridable Sub OnTextChanged( _ 
   ByVal e As RoutedPropertyChangedEventArgs(Of Double) _ 
)  
protected: 
virtual void OnTextChanged(  
   RoutedPropertyChangedEventArgs<double>^ e 
)  

Parameters

e
A RoutedPropertyChangedEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate.

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