Utilisation des ressources dans WPF

Question

Je suis désireux d'utiliser l'exemple de

http://blogs.microsoft.co.il/blogs/tomershamam/archive/2008/09/22/lt-howto-gt-replace-listview-columns-with-rows-lt-howto-gt.aspx

Cependant, je ne veux pas mettre cela dans le code App.xaml que cela s'appliquera à tous gridviews, comment faire J'applique cet exemple à quelques gridviews sélectionnés dans l'application? Les ressources se présentent comme suit

J'ai essayé de créer un usercontrol et coller ce lot dans la section UserControl.Resources mais il ne fonctionne pas, je ne peux obtenir cet exemple pour travailler si je les ai mis dans l'application Section des ressources dont je ne veux évidemment pas. Aidez-moi!! :-)

Answer 1

Je pense qu'il y a une erreur dans votre code.

Je viens de copier à utiliser dans un projet de test et a obtenu une erreur:

StaticResource reference 'GridViewColumnHeaderGripper' was not found.

sur:

<Style TargetType="{x:Type GridViewColumnHeader}"> 

Answer 2

However I don't want to put this into the App.xaml code as this will apply to ALL gridviews, how do I apply this example to a select few gridviews in the application?

il suffit de changer la clé du style à être autre chose que GridView.GridViewScrollViewerStyleKey. Choisissez une clé personnalisée et définissez l'explicitation de style sur les contrôles qui en ont besoin ({StaticResource styleKey})
