Fenêtre WPF affiche vide

Question

Excel AddIn, C#, .net 4.0, windows 7, ruban mon addin a un onglet de ruban, plusieurs boutons de ruban, quand un ruban est cliqué, l'addin enverra plusieurs appels de service Web et une fenêtre affichera des données dans les onglets, treeview, gridview etc. Les données dans treeview, gridview sont peuplées à partir d'appels de service Web. Tout a fonctionné pour un utilisateur final particulier jusqu'à hier Quand il a cliqué sur le bouton, la fenêtre semble apparaître, mais il est un peu derrière Excel et ne pouvait pas être mis au point. En outre, il est vide sans tabulation, arborescence, gridview, etc. J'ai vérifié que tous les appels de service Web retournent correctement. L'utilisateur a Windows 7, Excel 2010 (32 bits). Je n'ai aucune idée de ce qui pourrait causer cela. S'il vous plaît aider. c'est ma fenêtre WPF. grâce

Answer 1

Je sais que c'est vieux - mais nous avons trébuché à cela avec un bureau d'héritage complément que nous soutenons - où un utilisateur connaît apparemment ce même problème.

Nous avons fait quelques recherches, et trébuché à travers cette même SO après: Blank WPF child windows on Windows 10

On dirait qu'il ya deux options:

1. Demandez à l'utilisateur de mettre à jour/corriger les mauvais pilotes de carte vidéo.

2. Mettez un hack dans le code qui la force le contenu de redessiner au bon moment (à savoir InvalidateVisual ne suffit pas, voir les réponses des questions liées à plus d'informations).
