WPF ListBox横向布局并支持鼠标横向滚动

xaml代码：

<ItemsPanelTemplate x:Key="ItemsPanelTemplate1">
　　<VirtualizingStackPanel Orientation="Horizontal" IsItemsHost="True"/>
</ItemsPanelTemplate>

<ListBox x:Name="listbox"
                             ItemsPanel="{DynamicResource ItemsPanelTemplate1}"
                             ScrollViewer.CanContentScroll="False" 
                             ScrollViewer.PanningMode="HorizontalOnly" 
                             ItemContainerStyle="{DynamicResource ListBoxItemStyleGroup1}"
                             HorizontalContentAlignment="Center"
                             ScrollViewer.HorizontalScrollBarVisibility="Hidden">

            InitializeComponent();
            listbox.AddHandler(ListBox.MouseWheelEvent, new MouseWheelEventHandler(ListBox_MouseWheel), true);
}
 
private void ListBox_MouseWheel(object sender, MouseWheelEventArgs e)
{
            ItemsControl items = (ItemsControl)sender;
            ScrollViewer scroll = FindVisualChild<ScrollViewer>(items);
            if (scroll != null)
            {
                int d = e.Delta;
                int currentNum = 0;
                var horOffset = (int)Math.Round(scroll.HorizontalOffset);
                if (d > 0)
                {
                    scroll.LineLeft();
                    currentNum = horOffset / (int)ListSignal.ActualWidth + 1;
                }
                if (d < 0)
                {
 
                    scroll.LineRight();
                    currentNum = horOffset / (int)ListSignal.ActualWidth + 1;
                }
                scroll.ScrollToTop();
            }
