I'm using Callisto and C# too, and this is how I solved the problem.

    void OnCommandsRequested(SettingsPane sender, SettingsPaneCommandsRequestedEventArgs args)
    {
        var settings = new SettingsCommand("settings", "Settings", new UICommandInvokedHandler(showSettings));
        args.Request.ApplicationCommands.Add(settings);
        var credits = new SettingsCommand("credits", "Credits", new UICommandInvokedHandler(showCredits));
        args.Request.ApplicationCommands.Add(credits);
    }

    public void showSettings(IUICommand command)
    {
        var settings = new SettingsFlyout();
        settings.Content = new SettingsUserControl();
        settings.HeaderBrush = new SolidColorBrush(_background);
        settings.Background = new SolidColorBrush(_background);
        settings.HeaderText = "Settings";
        settings.IsOpen = true;
    }

    public void showCredits(IUICommand command)
    {
        var settings = new SettingsFlyout();
        settings.Content = new CreditsUserControl();
        settings.HeaderBrush = new SolidColorBrush(_background);
        settings.Background = new SolidColorBrush(_background);
        settings.HeaderText = "Credits";
        settings.IsOpen = true;
    }

Then from other pages I can just call

((App)Application.Current).showCredits(null);

or 

((App)Application.Current).showSettings(null);

To bring up the settings pane I want to see :o)

The first step is to add a listener for the CommandsRequest event on the SettingsPane for the page where you want the setting to be displayed. For example:

SettingsPane.GetForCurrentView().CommandsRequested += MainPage_CommandsRequested;

Then define the event handler

void MainPage_CommandsRequested(SettingsPane sender, SettingsPaneCommandsRequestedEventArgs args)
{
    SettingsCommand generalCommand = new SettingsCommand("GeneralSettings", ResourceLoader.GetString("GeneralText"), (x) =>
    {
        SettingsFlyout settings = new SettingsFlyout();
        settings.HeaderBrush = Resources["SettingsHeaderBrush"] as SolidColorBrush;
        settings.HeaderText = ResourceLoader.GetString("GeneralText");
        settings.Background = new SolidColorBrush(Windows.UI.Colors.White);
        settings.Content = new GeneralSettingsFlyout();
        settings.IsOpen = true;
        settings.Height = Window.Current.Bounds.Height;

        // Optionally, add a closed event handler
        settings.Closed += settings_Closed;
    });
}

Note that in this scenario, GeneralSettingsFlyout is simply a Page which will be loaded into the settings pane once that particular setting is selected (Callisto automatically handles this).

SettingsFlyout is the class from Callisto.

Edit your app.xaml file and reference this snippet for your code:

App::OnLaunched()
{
.
.
     var rootFrame = new CharmFrame { CharmContent = new CharmFlyouts() };
     SuspensionManager.RegisterFrame(rootFrame, "AppFrame");
.
.
}

Then, when you want to display that setting, do this:

SomeOtherMethod()
{
     ((Window.Current.Content as CharmFrame).CharmContent as CharmFlyouts).ShowSettings();
}
