Data Binding with WPF DataGrid - VB.NET

I am working on a display that needs to show an array of objects in a DataGrid (WPF). Each object has two properties, one is a simple number (Base) the other is an array of numbers (Data). I have created some test data as a small array of these objects and bound it to the ItemsSource property of my DataGrid. I get the first column displayed (the Base value) but I cannot figure out how to get each entry from the Data array into a column.

Ultimately the Data columns will need to be edited but this first step has me stumped.
Thanks in advance for any input,

Maybe this will help.

public class TestRow
    private bool[] _values = new bool[10];
    public bool[] Values
        get { return _values; }
        set { _values = value; }

    public TestRow(int seed)
        Random random = new Random(seed);
        for (int i = 0; i < Values.Length; i++)
            Values[i] = random.Next(0, 2) == 0 ? false : true;

Open in new window

DataGrid grid = new DataGrid();
var data = new TestRow[] { new TestRow(1), new TestRow(2), new TestRow(3) };
grid.AutoGenerateColumns = false;
for (int i = 0; i < data[0].Values.Length; i++)
    var col = new DataGridCheckBoxColumn();
    //Here i bind to the various indices.
    var binding = new Binding("Values[" + i + "]");
    col.Binding = binding;
grid.ItemsSource = data;

Open in new window

using data[0].Values.Length when creating the columns could obviously throw an exception if the data collection is empty.
