Modern UI - Modern Menu zeigt keinen Link Inhalt

Question

Ich schreibe eine WPF-Anwendung basierend auf FirtsFloorSoftware Modern UI. Ich habe Probleme, wenn ich versuche, den Inhalt (UserControl) mit 'Source =' in einem Link anzuzeigen. Um das Problem anzuzeigen, habe ich eine kleine separate App erstellt.

Das Problem ist, dass der Inhalt von Link 2 (SecondPage.xaml) nie angezeigt wird. Ich habe im Internet nach Hinweisen gesucht, um das Problem zu lösen, aber kein Glück.

Bitte helfen Sie mir.

Auf Ihrer FirstPage.xaml könnten Sie eine ModernTab zB verwenden

<StackPanel Style="{StaticResource ContentRoot}"> 
    <TextBlock Text="First page" /> 
    <mui:ModernTab Layout="List"> 
     <mui:ModernTab.Links> 
      <mui:Link Source="/SecondPage.xaml" DisplayName="Second Page"></mui:Link> 
     </mui:ModernTab.Links> 
    </mui:ModernTab> 
</StackPanel> 

Alternativ können Sie von First zu NochNeSeite hinter der Verwendung navigieren Code und packt das Frame Objekt. Siehe unten

FirstPage.xaml

<Grid Style="{StaticResource ContentRoot}"> 
    <TextBlock Text="First page" /> 
    <Button x:Name="SecondPageButton" Content="Goto Second Page" Click="SecondPageButton_Click"></Button> 
</Grid? 

Navigieren auf Button-Click-Ereignis FirstPage.xaml.cs

private void SecondPageButton_Click(object sender, RoutedEventArgs e) 
{ 
    var frame = FirstFloor.ModernUI.Windows.Navigation.NavigationHelper.FindFrame(null, this); 

    if (frame != null) 
     frame.Source = new Uri("/SecondPage.xaml", UriKind.Relative); 
} 

Hoffnung, die
