如何在wp8中將動畫添加到網格

Question

我有一個網格控件。在按鈕上單擊，此網格將可見。在后端代碼中，我在按鈕單擊中向網格中添加了子元素。我希望此網格以特定的樣式加載並帶有特定的動畫。 請提出解決方案

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

在后端：

MenuUserControl menu = new MenuUserControl();
menu.Visibility = Visibility.Visible;
menu.HorizontalAlignment = HorizontalAlignment.Left;
menu.VerticalAlignment = VerticalAlignment.Top;
menu.Width = 200;
menuholder.Children.Add(menu);
menuholder.Visibility = Visibility.Visible;
isMenuVisible = false;
Canvas.SetZIndex(menu, 2);

您可以為網格創建一個情節提要

在您的xaml.cs代碼中

在您的按鈕操作上啟動Storyborad，例如：

grdStoryBoard.Begin();

您可以相應地更改動畫類型，請參見： http : //msdn.microsoft.com/zh-cn/library/windowsphone/develop/jj206955(v=vs.105).aspx

借助Blend可以很好地創建情節提要。請參閱： http : //msdn.microsoft.com/zh-cn/library/windows/apps/jj129478.aspx
