Called before the TextInput event occurs.
Assembly: System.Windows (in System.Windows.dll)
'Declaration Protected Overrides Sub OnTextInput ( _ e As TextCompositionEventArgs _ )
protected override void OnTextInput( TextCompositionEventArgs e )
Provides data about the event.
The OnTextInput method is called before any event handler for the TextInput event is called. This method allows derived classes to handle the TextInput event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding the OnTextInput method in a derived class, be sure to call the base class’s OnTextInput method so that registered delegates receive the event.
