示例
1、ToolTip 的示例
Controls/FlyoutControl/ToolTipDemo.xaml

<Grid Background="Transparent">
<StackPanel Margin="10 0 10 10">
<!--
ToolTip - 提示框控件
Content - 提示内容
Placement - 提示框的显示位置（Bottom, Right, Mouse, Left, Top）
HorizontalOffset - 水平偏移量
VerticalOffset - 垂直偏移量
IsOpen - 提示框是否是显示状态（如果要设置此属性的话，需要等到宿主加载完之后再设置）
Closed - 提示框关闭后触发的事件
Opened - 提示框打开后触发的事件
注：我这里测试 ToolTip 的最大宽度是 320
-->
<TextBlock Name="textBlock1" Text="TextBlock" Margin="5"
ToolTipService.ToolTip="ToolTip 的内容"
ToolTipService.Placement="Right" />
<TextBlock Name="textBlock2" Text="TextBlock" Margin="5">

3、PopupMenu 的示例

</Page>
　　Controls/FlyoutControl/PopupMenuDemo.xaml.cs



/*
* PopupMenu - 上下文菜单（未继承任何类）
*     Commands - 上下文菜单中的命令集合，返回 IList<IUICommand> 类型的数据

*     
* IUICommand - 命令
*     Label - 显示的文字
*     Id - 参数
*
* UICommandSeparator - 分隔符

// 在指定的位置显示上下文菜单，并返回用户激发的命令（测试的时候这里有时会发生异常，不知道什么原因，所以还是尽量用 MenuFlyout 吧）

if (chosenCommand == null) // 用户没有在上下文菜单中激发任何命令
            {
