How to apply ScrollBar and ListBoxItem styles on only one ListBox?

Question

I have a style that targets any ScrollBar by the Key in the app.xaml:

x:Key="{x:Type ScrollBar}" 

but the problem is that it's applied on any scroll bar in the application, the same happens for the ListBoxItem. How to apply it on only one ListBox, so I can use a string-based key, for example, I'm looking for something like this AP in the ListBox

ScrollBar.Style="{StaticResource ScrollBarStyle}"

Answer 1

Try to add an explicit Style to <ListBox.Resources>:

<ListBox>
    <ListBox.Resources>
        <Style TargetType="ScrollBar" BasedOn="{StaticResource ScrollBarStyle}" />
    </ListBox.Resources>
    ...
</ListBox>
