Ejemplos

En el ejemplo de código siguiente se muestra un métodoreemplazado WebPart.PartCommunicationMainque crea una instancia de la clase ParametersOutReadyEventArgs para enviar cuando se produce el evento ParametersOutReady . Este ejemplo de código forma parte de un ejemplo más extenso de la interfaz IParametersOutProvider .
