Controles/header non visible en design d'une Listview

**Harpist** · 17/06/2008, 15h24

Le bonjour à tous,

Dans le cadre de mon projet je suis en traind e confectionner un user control qui permet mis dans un expander de faire un gestion des recherches de façon dynamique (en gros on lui passe le nom de la table principal et l'utilisateur fait sa petite requete à sa sauce pour trouver ce qu'il cherche)

Bref...

Je devrait avoir qqchose dans ce goût là : http://img371.imageshack.us/img371/2...cherchemu6.jpg

Malheuseusement (étant débutant en WPF) j'avoue que je me tire les cheveux, car visuellement je ne vois rien dans mon listview (je devrais au moins voir les colonnes dans la partie design non ? parce que la c'est rien mais rien de rien)

C'est moi ou j'ai loupé qqchose ?

voici le debut du XAML pour comprendre

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Tu veux dire que là, tu ne vois rien dans ta ListView ? Même pas le Header ?

**Harpist** · 18/06/2008, 09h23

Tout à fait exact.

Salut,

je viens de tester et j'ai eu le même comportement (pas de colonne visible dans le designer Visual Studio)... J'ai ensuite essayé de créer une ListView via Blend et de récupérer le style défini par Blend pour le contrôle ListView et en l'utilisant ça fonctionne.

Donc en ajoutant ce style dans les ressources, les colonnes seront visibles dans le Designer Visual Studio :
