经过漫长的研发。我找到了解决方案： - ）

        var selector = sender as MultiSelector;

        //// with this way you can call the scrolling item into view even if the items are virtualized.
        //// works only for VirtualizingPanel.VirtualizationMode="Standard" not for recycle mode.
        var itemsHost = typeof(MultiSelector).InvokeMember("ItemsHost", BindingFlags.NonPublic | BindingFlags.GetProperty | BindingFlags.Instance, null, selector, null);

        VirtualizingPanel virtualPanel = itemsHost as VirtualizingPanel;
        if (virtualPanel != null && selector.SelectedIndex >= 0)
        {
            virtualPanel.BringIndexIntoViewPublic(selector.SelectedIndex);
        }
