Ejemplo de ControlTemplate de Frame

Actualización: noviembre 2007

Los controles de Windows Presentation Foundation (WPF) tienen un objeto ControlTemplate que contiene el árbol visual de ese control. Puede cambiar la estructura y la apariencia de un control si modifica la ControlTemplate de ese control. No existe ningún modo de reemplazar únicamente una parte del árbol visual de un control; para modificar el árbol visual de un control, debe establecer la propiedad Template del control en su nuevo y completo objeto ControlTemplate.

En este tema se muestra el objeto ControlTemplate del control Frame de WPF.
