Cómo: Hospedar un control de Windows Presentation Foundation en formularios Windows Forms mediante el uso de ElementHost

Actualización: noviembre 2007

La clase ElementHost permite hospedar un control de Windows Presentation Foundation (WPF) en formularios Windows Forms. Al hospedar el control, puede recibir los eventos y obtener acceso las propiedades expuestas del control. La manera más simple de hospedar un control de WPF es agregar un control Panel al formulario y, a continuación, hospedar el control de WPF en Panel. Esto se suele hacer en el controlador de eventos Load del formulario.

En el ejemplo de código siguiente se muestra cómo utilizar el control ElementHost para hospedar un control de WPF en formularios Windows Forms. También se muestra cómo asociar controladores a dos de los eventos OnButtonClick personalizados del control. Consulte Ejemplo Hosting a Simple Windows Presentation Foundation Control in Windows Forms para obtener el ejemplo completo.
