I want to bind this class to a Datagrid

class StringClass
{
public string StringNumber {get; set;}
public string Tuning {get; set;}
public List<string> Frets {get; set;}
}

I then have a List<StringClass> Fretboard;

So the result would be:
|#|Tuning|0 |1 |2 |...|<Frets.Count>|
|1| F# |F#|G |G#|...
....

So I was hoping that I could use
dataGrid1.ItemsSource = Fretboard;

But I fail because of the List<string> Frets part. I don't know how many
items there are in Frets. It depends on what the users selects.

How would you solve this?

I'm using VS2010 and .NET 4.0

PS! The datagrid will be read only

Ok, I have come up with an solution.

Had to change List<string> Frets {get; set;} to
List<FretClass> Frets {get; set;}

class FretClass
{
public string Value {get; set;}

public FretClass(string fretname)
{
Value = fretname;
}
}

Then from MainWindow.xaml.cs I do

DataGridTextColumn col = new DataGridTextColumn();
col.Header = "#";
col.Binding = new Binding("StringNumber");
dataGrid1.Columns.Add(col);

col = new DataGridTextColumn();
col.Header = "Tuning";
col.Binding = new Binding("Tuning");
dataGrid1.Columns.Add(col);
int maxFrets = m_Fretboard[0].Frets.Count;
for (int i = 0; i < maxFrets; i++)
{
col = new DataGridTextColumn();
col.Header = i.ToString();
col.Binding = new Binding("Frets[" + i.ToString() + "].Value");
dataGrid1.Columns.Add(col);
}

dataGrid1.ItemsSource = m_Fretboard;

It works! but there may be some more clever way of doing it, so...
