Я хочу использовать пример из

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

Однако я не хочу помещать это в код App.xaml, поскольку это будет применяться ко ВСЕМ сеточным представлениям. Как применить этот пример к нескольким избранным сеточным представлениям в приложении? Ресурсы выглядят так

<Style x:Key="{x:Static GridView.GridViewScrollViewerStyleKey}"
       TargetType="{x:Type ScrollViewer}">
        <Setter Property="Focusable"
            Value="false"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ScrollViewer}">
                    <Grid Background="{TemplateBinding Background}"

Я попытался создать usercontrol и закрепить этот лот в разделе UserControl.Resources, но он не сработал, я смогу заставить этот пример работать, только если поместил их в раздел Application.Resources, чего, очевидно, у меня нет хочу. Помогите!! : -)

Просто измените ключ стиля на что-то отличное от GridView.GridViewScrollViewerStyleKey. Выберите пользовательский ключ и настройте стиль на элементах управления, которым он нужен (с помощью {StaticResource styleKey})

Ссылка на StaticResource 'GridViewColumnHeaderGripper' не найдена.

на:
