解决ListBox拦截滚轮滚动事件

问题：<ScrollViewer><ListBox Name="ListBox_Answers" /></ScrollViewer> 这个结构导致ListBox拦截了滚轮事件

解决：

xaml

<ScrollViewer>      <ListBox Name="ListBox_Answers" PreviewMouseWheel="ListBox_Answers_PreviewMouseWheel" >       </ListBox></ScrollViewer>

xaml.cs

private void ListBox_Answers_PreviewMouseWheel(object sender, 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);            }        }

总结：

拦截滚轮事件，new一个新事件，父控件RasizeEvent
