Comentarios

En tiempo de ejecución para la clase ResourcesAttribute busca el CustomPropertyToolPart . Si se encuentra, la CustomPropertyToolPart itera a través del método LoadResource (debe invalidar este método) con los valores de recursos desde el ResourcesAttribute. Si no se encuentra el recurso, se crea la interfaz de usuario de CustomPropertyToolPart con los valores predeterminados. De lo contrario, se crea la interfaz de usuario de CustomPropertyToolPart con los valores traducidos. Microsoft .NET Framework sólo proporcionará los valores de localización para la etiqueta de propiedad, descripciones y rótulo de categorías. No se traducirá el nombre de la propiedad base. Si no se define la clase ResourcesAttribute , la interfaz de usuario de CustomPropertyToolPart volverá a los metadatos no localizada (es decir, CategoryAttribute, DescriptionAttribute, FriendlyNameAttributey el nombre interno de la propiedad).

Ejemplos

En el ejemplo de código siguiente se muestra cómo localizar la propiedad personalizada cuando se muestra en la interfaz de usuario de CustomPropertyToolPart .
