我有WP7应用程序的问题.我正在尝试从WPF示例代码编写WP7应用程序.

    private void storyboard_Completed(object sender, EventArgs e)
    {
        ClockGroup clockGroup = (ClockGroup)sender;

        // Get the first animation in the storyboard, and use it to find the
        // bomb that's being animated.
        DoubleAnimation completedAnimation = (DoubleAnimation)clockGroup.Children[0].Timeline;
        Bomb completedBomb = (Bomb)Storyboard.GetTarget(completedAnimation);

似乎没有ClockGroup类,而Storyboard没有GetTarget方法(这有点奇怪,因为有SetTarget方法).是否有一个hack来获得相同的功能？
