Персонализиран стил на WPF Xaml Избран стил на елемент в ListBox

Имам ListBox, който превърта изображения хоризонтално.

Имам следния XAML, използвах смес, за да го създам. Първоначално имаше x:Key на реда Style TaregetType, MSDN каза да го премахна, тъй като получавах грешки за това. Сега получавам тази грешка:

Error 3 Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead.

Не разбирам как да приложа всички тези боклуци по този начин, пробвах няколко неща, нищо не работи.

Целта ми е фонът на избрания елемент да е бял, а не син. Изглежда като много работа за нещо толкова малко!

Благодаря.

Увийте стиловия етикет с ItemContainerStyle, както е показано по-долу:

<ListBox ItemsSource="{Binding Source={StaticResource WPFApparelCollection}}"
         Grid.Row="1" Margin="2,26,2,104"
         ScrollViewer.VerticalScrollBarVisibility="Hidden"
         ScrollViewer.HorizontalScrollBarVisibility="Hidden" 
         SelectionMode="Single"
         x:Name="list1" MouseLeave="List1_MouseLeave" MouseMove="List1_MouseMove" 
         Style="{DynamicResource ListBoxStyle1}"  >

        <ListBox.ItemContainerStyle>
            <Style TargetType="{x:Type ListBoxItem}">
                <Setter Property="Background" Value="Transparent"/>
            </Style>
<!-- the rest of your code,  but close the ItemContainerStyle -->
        </ListBox.ItemContainerStyle> 
    </ListBox>

Опитах горното решение, но то не работи според очакванията, така че намерих друг начин да разреша проблема си, който е да деактивирам избора за списъчно поле

това направих аз

<ListBox.ItemContainerStyle>
    <Style TargetType="{x:Type ListBoxItem}">
         <Setter Property="Focusable" Value="False"/>
     </Style>
</ListBox.ItemContainerStyle>
