如何在图钉布局中单击箭头时导航到另一个页面?
App.xaml页面代码:
<Application.Resources>
<Style x:Key="MenuItemsStyle" TargetType="sltkit:MenuItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="sltkit:MenuItem">
<StackPanel>
<TextBlock Text="{Binding Name}"
TextWrapping="Wrap"
Margin="24,0"
FontSize="26"/>
<TextBlock Text="{Binding Description}"
TextTrimming="WordEllipsis"
Margin="24,0"
FontSize="22"/>
<TextBlock Text="{Binding DatetimeAdded}"
TextTrimming="WordEllipsis"
Margin="24,0"
FontSize="22"/>
<Image Source="/MyBuddies;component/Images/decline.png" Height="20" Width="20" Margin="200,0" Stretch="Fill" Name="imgDecline" >
</Image>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="MenuStyle" TargetType="sltkit:ContextMenu">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border CornerRadius="8" Margin="24"
BorderBrush="Green" BorderThickness="2">
<Border.Background>
<LinearGradientBrush
StartPoint="0.5,0" EndPoint="0.5,1">
<GradientStop Color="White"
Offset="0.0"/>
<GradientStop Color="LightBlue"
Offset="0.5"/>
</LinearGradientBrush>
</Border.Background>
<ItemsPresenter />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Application.Resources>
in mainpage.xaml
<my:MapItemsControl.ItemTemplate>
<DataTemplate>
<my:Pushpin
Background="Blue"
Location="{Binding Location}" Tap="Pushpin_Tap">
<sltkit:ContextMenuService.ContextMenu>
<sltkit:ContextMenu IsZoomEnabled="False">
<sltkit:MenuItem Style="{StaticResource MenuItemsStyle}"/>
</sltkit:ContextMenu>
</sltkit:ContextMenuService.ContextMenu>
</my:Pushpin>
</DataTemplate>
</my:MapItemsControl.ItemTemplate>
</my:MapItemsControl>
点击图钉显示说明。点击时需要在该布局中放置一个箭头,将一些值传递到另一个页面。如何实现这一点?请告诉我......

在App.xaml中编写一些UI代码不是一个好习惯。 App.xaml和App.xaml.cs用于处理应用程序生命周期事件,如启动,关闭,激活和停用事件以及共享某些全局数据。
如果您仍想使用,那么在后面的代码中您可以使用以下代码从App.xaml导航到另一个页面
(Application.Current.RootVisual as PhoneApplicationFrame).Navigate(new Uri("/AnotherPage.xaml", UriKind.RelativeOrAbsolute));
