wpf listbox problem

[pat3d]

Hi,

I have created a listbox with items in XAML file using VS2008. (for a WPF Browser application)
I'm selecting a item with the mouse, and when I'm using the up and down keys of the keyboard and reach the top or the bottom of the listbox, it goes out the listbox.

Is there a way not to leave the listbox ?

I hope I'm clear enough in my explanation.

If anyone can help.

Thanks in advance,
