禁用FameworkElement中的RequestBringIntoViewEvent事件即可，

Xaml:

<ListBox >
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<EventSetter Event="RequestBringIntoView" Handler="ListBoxItem_RequestBringIntoView"></EventSetter>
</Style>
</ListBox.ItemContainerStyle>

</ListBox >

后台事件：

private void ListBoxItem_RequestBringIntoView(object sender, RequestBringIntoViewEventArgs e)
{
e.Handled = true;
}
