J'ai ce problème: Après l'instanciation de cette fenêtre, ouvrez tous les expandeurs imbriqués sur le côté droit. (il y en a 7). Le dernier contient des éléments. (TextBoxes) Essayez de faire glisser le GridSplitter. Tout va bien, ça fonctionne couramment. MAIS! Dès que je clique sur l'un des TextBox (peu importe lequel), le glisser devient fou (après une chute de souris parfois 3 secondes +). Après avoir cliqué sur dans la zone de texte de ces messages de débogage apparaissent dans la sortie:GridSplitter se déplaçant très lentement
Après cela, le traînement lent fou a lieu. Dans la fenêtre de débogage et d'aller en pause à l'étape suivante sont ces messages affichés:
'WpfApplication1.vshost.exe' (Managed): Loaded 'C:\Windows\assembly\GAC_MSIL\PresentationCore.resources\3.0.0.0_de_31bf3856ad364e35\PresentationCore.resources.dll'

Eh bien, je viens d'essayer toutes les configurations possibles, x86, x64 et Any CPU en mode de débogage/libération. Pas de changement. Avec chaque contrôle ajouté au bloc où sont toutes ces TextBoxes il est plus lent (avec 3 scrollviewers imbriqués ~ 25 secondes chaque glisser) –
Je l'ai essayé sur d'autres machines avec les mêmes versions OS/.NET/correctifs installés et ça fonctionne vraiment couramment ! Que diable est avec mon installation .NET (toutes les machines ont été restaurer à partir de la même image) –
bien .. je ne peux pas vraiment réinstaller l'installation. C'est le composant de base de win 7 apparemment .. –
