how to send data from datagridview to database with progress bar using c#.net

Here i am simply giving the link for sending data to database.

void Save()
        {
            try
            {
                if (dataGridView1.Rows.Count > 1)
                {
                    for (int i = 0; i <= dataGridView1.Rows.Count - 1; i++)
                    {
                        string col1 = dataGridView1.Rows[i].Cells[0].Value.ToString();
                        string col2 = dataGridView1.Rows[i].Cells[1].Value.ToString();
                        string col3 = dataGridView1.Rows[i].Cells[2].Value.ToString();
                        string col4 = dataGridView1.Rows[i].Cells[3].Value.ToString();
                        string col5 = dataGridView1.Rows[i].Cells[4].Value.ToString();
                        using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["constr"].ConnectionString))
                        {
                            string insert = "INSERT INTO InvoiceItems(SNo,Quantity,Rate,Description,Total) VALUES (@SNo,@Quantity,@Rate,@Description,@Total)";
                            con.Open();
                            SqlCommand cmd = new SqlCommand(insert, con);
                            cmd.Parameters.AddWithValue("@SNo", col1.ToString());
                            cmd.Parameters.AddWithValue("Description", col2.ToString());
                            cmd.Parameters.AddWithValue("@Quantity", col3.ToString());
                            cmd.Parameters.AddWithValue("@Rate", col4.ToString());
                            cmd.Parameters.AddWithValue("Total", col5.ToString());
                            cmd.ExecuteNonQuery();
                            con.Close();
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                ex.Message.ToString();
            }
        }

I have not attached the progress bar in it.
