有些时候我们需要在一个控件里获取鼠标滚轮事件

1. 构造函数注册事件

this.PreviewMouseWheel += new System.Windows.Input.MouseWheelEventHandler(this.Kk_MouseWheel);

2. 事件实现

private void Kk_MouseWheel(object sender, MouseWheelEventArgs e)
        {
            int delta = e.Delta;


            var ss = LineNo;

            RoutedEventArgs arg = new RoutedEventArgs(HLZD.Infrastructure.SMS.MemoryEntitys.MGlobalData.Mousewell, delta.ToString()+"|"+ LineNo);

            this.RaiseEvent(arg);
        }
