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