如果scrollviewr里有一个listbox可以滚动，如果加个面板，放俩个listbox就无法滚动。两天都没进展，突然眼前一亮搜出来，代码搬运工的悲哀......，感谢前辈了。

每次都换个关键字搜索下试试。搜来搜去就喷到了。。。。。。

cs为

        public void bindLBX()
        {
       
       
            LB1.PreviewMouseWheel += (sender, e) =>
            {

                var eventArg = new MouseWheelEventArgs(e.MouseDevice, e.Timestamp, e.Delta);

                eventArg.Source = sender;

                this.LB1.RaiseEvent(eventArg);
               
            };

            LB2.PreviewMouseWheel += (sender, e) =>
            {

                var eventArg = new MouseWheelEventArgs(e.MouseDevice, e.Timestamp, e.Delta);

                eventArg.RoutedEvent = UIElement.MouseWheelEvent;

                eventArg.Source = sender;

                this.LB2.RaiseEvent(eventArg);

            };
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            bindLBX();
        }
