C# 如何在wp8中向网格添加动画

我有一个网格控件。单击按钮时，此网格将可见。在后端代码中，我在单击按钮时向网格添加了子元素。我希望此网格以特定模式加载，并带有特定动画。请提出解决办法

<Grid x:Name="menuholder" Height="Auto" Canvas.ZIndex="1" 
      Grid.RowSpan="5" HorizontalAlignment="Right" 
      VerticalAlignment="Top" Margin="0,0,15,0">
</Grid>

可以为网格创建情节提要

可以相应地更改动画类型 参考：

借助Blend可以很好地创建故事板

请参阅：

您可能正在制作您想要的动画，但您没有提供您尝试过的内容或所需结果的任何详细信息。你们看过故事板了吗？我看过故事板，但无法满足我的要求。也就是说，我的网格大部分来自右上角，必须在其位置可见。我不知道这意味着什么。你能更好地描述你想要实现的动画吗？如果你不能用故事板，我怀疑你需要用定时器（我不推荐）手动操作。如果你想给自动调整大小的控件的高度设置动画，你就不能。您需要决定是否尝试不同的效果，或者使用以下内容：我通过上述解决方案成功加载网格动画我想卸载它，或者删除带有特定动画的子控件我应该添加哪些额外代码
