Called before the TextInput event occurs.
Assembly: System.Windows (in System.Windows.dll)
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
