How to Focus on ListviewItem in WPF?

Question

I have ListBox in my application with Ten items, user can see five items at time. Sometimes I'm selecting items from code and setting focus.

Selecting an item and focusing work perfectly when items are visible on Form, but for other non-visible items, I'm unable to set the focus (NOTE: after selecting it is visible to user).

Can anyone help me please?

var item = _listView.ItemContainerGenerator.ContainerFromIndex(index) as ListBoxItem;

if (item != null)
{
   item.Focus();
}

Have you tried:

_listView.SelectedIndex = index;

var item = _listView.ItemContainerGenerator.ContainerFromIndex(index) as ListBoxItem;
if (item != null)
{
   item.Focus();
}
