Controls/FlyoutControl/ToolTipDemo.xaml.cs
/** ToolTip - 提示框控件(继承自 ContentControl, 请参见 /Controls/BaseControl/ContentControlDemo/)*/using Windows.UI.Xaml; using Windows.UI.Xaml.Controls;namespace Windows10.Controls.FlyoutControl {public sealed partial class ToolTipDemo : Page{public ToolTipDemo(){this.InitializeComponent();}private void toolTip_Opened(object sender, RoutedEventArgs e){lblMsg.Text = "textBlock2 toolTip_Opened";}private void toolTip_Closed(object sender, RoutedEventArgs e){lblMsg.Text = "textBlock2 toolTip_Closed";}} }
2、Popup 的示例
Controls/FlyoutControl/PopupDemo.xaml
<Pagex:Class="Windows10.Controls.FlyoutControl.PopupDemo"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:local="using:Windows10.Controls.FlyoutControl"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"mc:Ignorable="d"><Grid Background="Transparent"><StackPanel Margin="10 0 10 10"><!--Popup - 弹出框控件Child - 弹出框的内容([ContentProperty(Name = "Child")]),一个 UIElement 类型的对象ChildTransitions - 显示弹出框时,其内容的过渡效果IsLightDismissEnabled - 点击非 Popup 区域时否关闭 PopupHorizontalOffset - 水平方向上的偏移量VerticalOffset - 垂直方向上的偏移量--><Popup Name="popup" Margin="5" HorizontalOffset="200" VerticalOffset="10" IsLightDismissEnabled="{Binding IsChecked, ElementName=chkIsLightDismissEnabled}"><Border BorderBrush="Red" BorderThickness="1" Background="Orange" Width="200" Height="200"><StackPanel HorizontalAlignment="Center" VerticalAlignment="Center"><TextBlock Text="我是 Popup" HorizontalAlignment="Center" /><Button Name="btnClosePopup" Content="关闭" HorizontalAlignment="Center" Click="btnClosePopup_Click" /></StackPanel></Border><!--为弹出框增加 PopupThemeTransition 效果--><Popup.ChildTransitions><TransitionCollection><PopupThemeTransition /></TransitionCollection></Popup.ChildTransitions></Popup><TextBlock Name="lblMsg" Margin="5" /><!--显示 xaml 方式定义的 popup--><StackPanel Orientation="Horizontal" Margin="5"><Button Name="btnOpenPopup" Content="弹出 Popup" Click="btnOpenPopup_Click" /><CheckBox Name="chkIsLightDismissEnabled" IsChecked="False" Content="IsLightDismissEnabled" Margin="10 0 0 0" /></StackPanel><!--显示 code-behind 方式定义的 popup--><Button Name="btnOpenPopupToast" Content="弹出仿 toast 的 Popup" Click="btnOpenPopupToast_Click" Margin="5" /></StackPanel></Grid> </Page>
Controls/FlyoutControl/PopupDemo.xaml.cs

3、PopupMenu 的示例
Controls/FlyoutControl/PopupMenuDemo.xaml
<Pagex:Class="Windows10.Controls.FlyoutControl.PopupMenuDemo"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:local="using:Windows10.Controls.FlyoutControl"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"mc:Ignorable="d"><Grid Background="Transparent"><StackPanel Margin="10 0 10 10"><TextBlock Name="lblMsg" Margin="5" /><TextBlock Name="lblDemo" Margin="5">鼠标右键我或触摸 press-and-hold 我,以弹出 PopupMenu</TextBlock></StackPanel></Grid> </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* IAsyncOperation<IUICommand> ShowAsync(Point invocationPoint) - 在指定的位置(PopupMenu 的默认显示位置在窗口 0,0 点)上显示上下文菜单,并返回用户激发的命令* IAsyncOperation<IUICommand> ShowForSelectionAsync(Rect selection, Placement preferredPlacement) - 在指定的矩形区域的指定方位显示上下文菜单,并返回用户激发的命令* * IUICommand - 命令* Label - 显示的文字* Id - 参数** UICommandSeparator - 分隔符*/using System; using Windows.UI.Popups; using Windows.UI.Xaml; using Windows.UI.Xaml.Controls; using Windows.UI.Xaml.Input; using Windows10.Common;namespace Windows10.Controls.FlyoutControl {public sealed partial class PopupMenuDemo : Page{public PopupMenuDemo(){this.InitializeComponent();lblDemo.RightTapped += lblDemo_RightTapped;}private async void lblDemo_RightTapped(object sender, RightTappedRoutedEventArgs e){PopupMenu menu = new PopupMenu();menu.Commands.Add(new UICommand("item1", (command) =>{lblMsg.Text = string.Format("command label:{0}, id:{1}", command.Label, command.Id);}, "param1"));menu.Commands.Add(new UICommand("item2", (command) =>{lblMsg.Text = string.Format("command label:{0}, id:{1}", command.Label, command.Id);}, "param2"));// 分隔符menu.Commands.Add(new UICommandSeparator());menu.Commands.Add(new UICommand("item3",(command) =>{lblMsg.Text = string.Format("command label:{0}, id:{1}", command.Label, command.Id);}, "param3"));// 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)IUICommand chosenCommand = await menu.ShowForSelectionAsync(Helper.GetElementRect((FrameworkElement)sender), Placement.Below);if (chosenCommand == null) // 用户没有在上下文菜单中激发任何命令 {lblMsg.Text = "用户没有选择任何命令";}else{lblMsg.Text += Environment.NewLine;lblMsg.Text += string.Format("result label:{0}, id:{1}", chosenCommand.Label, chosenCommand.Id);}}} }
