Il vous manque la liaison de données.

C#

private void Button1_Click(object sender, EventArgs e)
{
    DataTable tab = new DataTable();
    tab.Columns.Add("matricule", Type.GetType("System.Int32"));
    tab.Columns.Add("nom", Type.GetType("System.String"));
    tab.Columns.Add("part", Type.GetType("System.Int32"));
    for (int i = 0; i <= dg.Rows.Count - 1; i++)
    {

        DataRow dr = tab.NewRow();
        dr[0] = dg.Rows[i].Cells[0].Text;
        dr[1] = dg.Rows[i].Cells[1].Text;
        dr[2] = dg.Rows[i].Cells[2].Text;
        tab.Rows.Add(dr);
    }

    DataRow mdr = tab.NewRow();
    mdr[0] = Server.HtmlEncode(t1.Text);
    mdr[1] = Server.HtmlEncode(t2.Text);
    mdr[2] = Server.HtmlEncode(t3.Text);
    tab.Rows.Add(mdr);

    dg.DataSource = tab;
    dg.DataBind();
}
