WPF listbox嵌套模板后IsHitTestVisible的false或true

[冏程序]

XAML代码如下：

1、当listbox2的IsHitTestVisible的属性为false时，可对列表进行操作，但不支持鼠标滚轮操作；
2、当listbox2的IsHitTestVisible的属性为true时，不可对列表操作，能支持鼠标滚轮操作

获取 listbox2 中的ScrollViewer 对象 在鼠标滚轮事件中 通过 它的ScrollToVerticalOffset 方法控制VerticalOffset 值就可以了。 获取ScrollViewer方法参见： http://blog.csdn.net/duanzi_peng/article/details/17094639

大哥你这个方法不行啊，只要把那个熟悉IsHitTestVisible=true，listbox2上的事件根本就不触发？

listBox.PreviewMouseWheel += (sender, e) => { var eventArg = new MouseWheelEventArgs(e.MouseDevice, e.Timestamp, e.Delta); eventArg.RoutedEvent = UIElement.MouseWheelEvent; eventArg.Source = sender; ListBox.RaiseEvent(eventArg); }; 界面的构造函数加入这段代码，listBox为ListBox空间Name
