J'ai finalement eu ce travail, grâce au génie de M. Eric White. J'ai même réussi à supprimer l'utilisation de l'un des outils mentionnés ci-dessus (Word 2007 Content Control Toolkit). Voici les étapes que je suis en train de prendre:
- Créez le modèle data-bindable.
- Effectuez une copie du modèle dans lequel enregistrer les modifications.
- Retrieve the Custom XML du modèle en utilisant LINQ to XML et le SDK Open XML.
- Sérialiser l'entité LINQ to SQL à l'aide de DataContractSerializer.
- Utilisez LINQ to XML pour trouver le descendant approprié en fonction a) du nom de l'entité et b) du nom de la propriété. Remplissez-le avec les valeurs de l'entité sérialisée LINQ to SQL (ceci utilise une version modifiée de la méthode Clone() d'Eric).
- Replace the Custom XML dans le document avec le XML personnalisé cloné et rempli (avec la permission de Brian Jones).
- Fait!
J'ai joint les méthodes d'extension que je utilise les étapes ci-dessus ci-dessous:
