DataGridView Sample

I wrote the following sample showing how to use datagridview in code.

using System.Windows.Forms;
 
namespace DataGridViewDemo
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            InitializeDatagridView();
        }
 
        private void InitializeDatagridView()
        {
            string[] stringlist = "I Love You Tracy".Split();
            var bindingSource = new BindingSource();
            foreach (string s in stringlist)
            {
                bindingSource.Add(new SampleData {WordLength = s.Length, Word = s});
            }
            var dgView = new DataGridView {AutoGenerateColumns = false};
            var col1 = new DataGridViewColumn
                {
                    Name = "Word",
                    ValueType = typeof (string),
                    CellTemplate = new DataGridViewTextBoxCell(),
                    DataPropertyName = "Word"
                };
            var col2 = new DataGridViewColumn
                {
                    Name = "WordLength",
                    ValueType = typeof (int),
                    CellTemplate = new DataGridViewTextBoxCell(),
                    DataPropertyName = "WordLength"
                };
            dgView.Columns.Add(col1);
            dgView.Columns.Add(col2);
            dgView.DataSource = bindingSource;
            Controls.Add(dgView);
        }
 
        public class SampleData
        {
            public string Word { get; set; }
            public int WordLength { get; set; }
        }
    }
}

Thanks for advice from this link.
