DataGridView RowsAdded event not giving expected results

Hello,

Developing a C sharp Windows Forms program in VS 2013 Pro to consume a web service.

When I run this program:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using LakesideConsumeServices.LakesideServiceReference;

namespace LakesideConsumeServices
{
    public partial class Form1 : Form
    {
        int rowCountInt = 0;
        public Form1()
        {
            InitializeComponent();
        }

        private void downloadCustomersButton_Click(object sender, EventArgs e)
        {
            NopServiceClient serviceClient = new NopServiceClient();
            string[] sqlStatements = new string[] { "Select Top 110 * From [Customer]" };
            dataGridView1.DataSource = serviceClient.ExecuteDataSet(sqlStatements, usernameOrEmailTextBox.Text, userPasswordTextBox.Text).Tables[0];

            recordCountTextbox.Text = rowCountInt.ToString();
            rowCountInt = 0;
        }

        private void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
        {
            rowCountInt += 1;
        }
    }
}

recordCountTextbox.Text only shows a count of 4, while the grid displays 110 rows.

I used the debugger and it only hits the ExecuteDataSet line one time and the rowCountInt += 1 four times.

Why am I not getting a proper count of rows?

Any help would be gratefully appreciated.

Thanks,
Tony
