WPF ListBox ScrollBar theme issue

Hi,

I am having and issue with wpf list box scrollbar theme on windows 8 machine. We have written a common style for ListBox and ListBoxItem in our resource dictionary which works nicely on windows 7 machine.

But when our wpf application is run on windows 8. the listbox scrollbars appears to be flat(it renders the windows 8 default theme). The same issue occurred with combobox. The wpf combo box appeared flat on windows 8 machine.

For this we wrote the following code and it worked for combo box:

Uri uriMerge = new Uri("PresentationFramework.Aero;V3.0.0.0;31bf3856ad364e35;component\\themes/aero.normalcolor.xaml", UriKind.Relative);
                Resources.MergedDictionaries.Add(Application.LoadComponent(uriMerge) as ResourceDictionary); 

But this code doesnt seem to work for listbox scrollbar. It still appears flat style or windows 8 style.

What are we missing ? Any help would be great.

Regards,
Praneet
