当ListView嵌套ListView时，在内部ListView控件上使用鼠标滚轮会阻止事件传递到外层滚动事件。#

解决办法：#

在内部ListView 添加鼠标滚轮事件，将事件手动提交给父级元素。#

private void ListBox_PreviewMouseWheel(object sender, System.Windows.Input.MouseWheelEventArgs e)
  {
         if (!e.Handled)
         {
             e.Handled = true;

             var eventArg = new MouseWheelEventArgs(e.MouseDevice, e.Timestamp, e.Delta);
             eventArg.RoutedEvent = UIElement.MouseWheelEvent;
             eventArg.Source = sender;
             var parent = ((Control)sender).Parent as UIElement;
             parent.RaiseEvent(eventArg);
         }
     }
