在Windows 8应用程序中使用Hyperlink NavigateUri在xaml页面之间导航

Question

In Windows phone 8 application, it is possible to navigate between XAML pages using the hyperlink as shown below

Hyperlink MyLink = new Hyperlink();
MyLink.NavigateUri = new Uri("/Views/SamplePage.xaml?entryId=" + entryId, UriKind.Relative);

I am creating dynamic hyperlinks inside IValueConverter based on the content. I am porting the application to Windows 8 and i could not use the same code, as windows 8 supports only the navigation using the Frame

this.Frame.Navigate(typeof(SamplePage));

Is there any other way, i can use Hyperlinks to navigate between xaml pages in Windows 8 metro applications.

Or is there any way to get the current Frame from within IValueConverter to navigate between the pages?

Answer 1

Sounds like you are navigating in the ValueConverter- I personally would not do that.

Use the Frame object, create your own abstraction as a service, or use behaviors (which you of course can use converters with)

        <Grid x:Name="grid5" Grid.Row="1" Grid.Column="2" Background="Purple">
          <TextBlock x:Name="TextBox" VerticalAlignment="Center" HorizontalAlignment="Center" FontSize="45" Text="Navigation with param" Margin="0,165,3,165"/>
            <interactivity:Interaction.Behaviors>
              <core:EventTriggerBehavior EventName="Tapped">
                 <core:NavigateToPageAction TargetPage="Behaviors_And_Triggers.NewPage" Parameter="{Binding ElementName=TextBox,Path=Text}"/>
              </core:EventTriggerBehavior>
          </interactivity:Interaction.Behaviors>
        </Grid>

Dont forget to add the Behaviors SDK extension (Add Reference => Extensions => Behaviors) and namespace:

    xmlns:interactivity="using:Microsoft.Xaml.Interactivity"
    xmlns:core="using:Microsoft.Xaml.Interactions.Core"

Note: Behaviors_And_Triggers. NewPage => NewPage is the name of the page!
