ListView bind to List inside List

Question

I'm building a School App that can display your grades. I have the following DataStructure:

public class Rootobject
{
    public List subjects{ get; set; }
}

public class Subject
{
    public String name { get; set; }
    public int id { get; set; }
    public String teacher { get; set; }
    public GradeSet wirtten { get; set; }
    public GradeSet spoken { get; set; }
    public float average { get; set; }
}

public class GradeSet
{
    public float counts { get; set; }
    public List grades { get; set; }
    public float average { get; set; }
}

public class Grade
{
    public string name { get; set; }
    public string grade { get; set; }
}

I have an ObservableCollection from the type of "Subject"

subjects = new ObservableCollection();

I have 3 ListViews. One shows all the Subjects (name & teacher). That works already. How I bound it:

In the other 2 ListViews, in the first, I want to display the written grades (name & the grade itself), in the second, I want to display the spoken grades (name & the grade itself). The written and spoken grades ListView look the same, but how do I bind the grades and names to them? This is the ListView:

Since there is a written and spoken grade per subject you could bind the ItemsSource property of the "gradeView" to the SelectedItem property of the "SubjectsListView":

It is almost the same for the third ListView. Just change the path of the ItemsSource binding:

The second and third ListViews should then be populated as you select a corresponding subject in the first ListView.
