Navigate to Page and Selected Source

Sep 10, 2016 at 1:55 AM

I am trying to use an event to navigate to a content page as if the user had navigated to it. For instance in the example I would like to navigate to the about.xaml in the settings page.

I have been able to get to the about.xaml page, but the page presents itself as a page instead of showing the list menu and the about.xaml inside the content layout.
            var mf = (MainWindow) Application.Current.MainWindow;
            mf.ContentSource = new Uri("/Pages/SettingsPage.xaml", UriKind.Relative);
Would anyone be able to point me in the right direction.
