【WPF】ScrollViewer无法滚动的问题

还需要给ScrollViewer注册一个鼠标滚轮事件！

XAML：

<ScrollViewer x:Name="scrollViewer" Width="950" Height="480" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Hidden" PreviewMouseWheel="ScrollViewer_PreviewMouseWheel">    // ......</ScrollViewer >

后台代码实现：

// 使得ScrollViewer可以滚动private void ScrollViewer_PreviewMouseWheel(object sender, MouseWheelEventArgs e){    var eventArg = new MouseWheelEventArgs(e.MouseDevice, e.Timestamp, e.Delta);    eventArg.RoutedEvent = UIElement.MouseWheelEvent;    eventArg.Source = sender;    scrollViewer.RaiseEvent(eventArg);}

吐个槽：居然还有ScrollView控件不带滚动的。。。那要你有何用？？【摊手
