creating a datagridview form in c#

I`m new to c# and windows form applications. Right now, I want to create a Datagridview within my form, whose rows I want to fill with the properties of a business object. I followed the example from this msdn page: How to: Bind Objects to Windows Forms DataGridView Controls and created my own program, but instead of getting a similar result as in the msdn example I get a datagridview with three empty rows. What am I doing wrong? Here is my program:

using System;
using System.Windows.Forms;


public class Form3 : Form
{
    private DataGridView dataGridView1 = new DataGridView();
    private BindingSource bindingSource1 = new BindingSource();

    public Form3()
    {            
        this.Load += new System.EventHandler(EnumsAndComboBox_Load);
    }

    private void EnumsAndComboBox_Load(object sender, System.EventArgs e)
    {
        // Populate the data source.           
        bindingSource1.Add(new Test("bli", "bla", "blop", "ha", "ho", "he"));
        bindingSource1.Add(new Test("bli", "bla", "blop", "ha", "ho", "he"));

        // Initialize the DataGridView.
        dataGridView1.AutoGenerateColumns = false;
        dataGridView1.AutoSize = true;
        dataGridView1.DataSource = bindingSource1;

        // Initialize and add a text box column.
        DataGridViewColumn column = new DataGridViewTextBoxColumn();
        column.DataPropertyName = "Name1";
        column.Name = "Name1";
        dataGridView1.Columns.Add(column);

        // Initialize and add a check box column.
        column = new DataGridViewTextBoxColumn();
        column.DataPropertyName = "Name2";
        column.Name = "Name2";
        dataGridView1.Columns.Add(column);

        column = new DataGridViewTextBoxColumn();
        column.DataPropertyName = "Name3";
        column.Name = "Name3";
        dataGridView1.Columns.Add(column);

        column = new DataGridViewTextBoxColumn();
        column.DataPropertyName = "Name4";
        column.Name = "Name4";
        dataGridView1.Columns.Add(column);

        column = new DataGridViewTextBoxColumn();
        column.DataPropertyName = "Name5";
        column.Name = "Name5";
        dataGridView1.Columns.Add(column);

        column = new DataGridViewTextBoxColumn();
        column.DataPropertyName = "Name6";
        column.Name = "Name6";
        dataGridView1.Columns.Add(column);

        // Initialize the form.
        this.Controls.Add(dataGridView1);
        this.AutoSize = true;
        this.Text = "DataGridView object binding demo";
    }

    #region "test object"

        public Test(string s1, string s2, string s3, string s4, string s5, string s6)
