How to data bind a list of objects with a list property?












0















I have an object Classroom with a list Student, as shown below.



public class Classroom
{
public int Number
{
get;
set;
}

public List<Student> StudentList
{
get;
set;
}
}


My Student object look like this.



public class Student
{
public string Name
{
get;
set;
}
}


I am using Xamarin Forms to develop a cross platform app that shows a ListView of all the classroom numbers, as a header for the cell, and underneath a list of the students name.



This is my C# for the ListView.ItemSource



List<Classroom> ClassroomList = new List<Classroom>();

ClassroomList.add(new Classroom());
ClassroomList.add(new Classroom());
ClassroomList.add(new Classroom());

MyListView.ItemSource = ClassroomList;


My problem is that each Classroom object has a different amount of students in the list. I don't know how to use data binding in XAML or C# to list all the classroom numbers with a "sub list" of all the students.



Here is an example of what I am looking for



If anyone can help me use my data model to bind the data in my ListView. It would help a lot.



I've been looking all over the place to find the answer and this is the closest answer is I found.

  • you want to display a List of students, not classrooms. Use LINQ to create a list of Students that is grouped by Classroom, then bind that to a Grouped ListView

  • I looked into Grouped ListView is there a way to make it collapse and expand like my picture?
