How can i get a string value from a datagrid cell?
public partial class MainWindow : Window
{
    ObservableCollection<DataCell> spreadsheet = new ObservableCollection<DataCell>();

    public MainWindow()
    {
        //Communal Spreadsheet
        InitializeComponent();

        spreadsheet.Add(new DataCell("", "", "", "", "", ""));
        spreadsheet.Add(new DataCell("", "", "", "", "", ""));
        spreadsheet.Add(new DataCell("", "", "", "", "", ""));
        spreadsheet.Add(new DataCell("", "", "", "", "", ""));
        spreadsheet.Add(new DataCell("", "", "", "", "", ""));
        spreadsheet.Add(new DataCell("", "", "", "", "", ""));
        spreadsheet.Add(new DataCell("", "", "", "", "", ""));
        spreadsheet.Add(new DataCell("", "", "", "", "", ""));

        dataGrid2.ItemsSource = spreadsheet;

}

private void dataGrid2_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
    {
        // I want to get the current cell value using the below
        // string myString = dataGrid1.CurrentItem.ToString();

        // the calculation seems to work with this when i pass it to textbox1 and set the myString Variable in the code.
        string myString = "10 * 10";

        string[] parts = myString.Split(' ');

        int part1 = int.Parse(parts[0]);
        //    string part2 = parts[1];
        int part3 = int.Parse(parts[2]);

        int answer = part1 * part3;
        string answer2 = answer.ToString();

        // dataGrid2.CurrentItem = answer2;

        // seems to work when i pass to the below textbox instead of back to the cell above
        textBox1.Text = answer2;
    }
}

((TextBox)e.EditingElement).Text
