                    ListViewItem lvi = new ListViewItem(row.Cells["Product"].Value.ToString()); 
                    lvi.SubItems.Add(row.Cells["Product"].Value.ToString());
                    listView1.Items.Add(lvi);
                    dataGridView1.CurrentCell = row.Cells["Product"];
                    dataGridView1.FirstDisplayedScrollingRowIndex = dataGridView1.Rows[row.Index].Index;
                    row = dataGridView1.Rows[i];
                    return;
                }

searchIndex = -1;
        button1.Text = "Find";
        listView1.Clear();

I want when search end, send message ... thanks

Mimicking the Find All functionality, populating your ListView will be very similar to the Find Next functionality. Here's an example if it were a separate button from Find Next:

public Form1()
{
  InitializeComponent();
  listView1.View = View.Details;
  listView1.Columns.Add("Column");
  listView1.Columns.Add("Row");
  listView1.Columns.Add("Value");
}

private void button2_Click(object sender, EventArgs e)
{
  button2.Text = "Find All";
  int tempIndex = -1;
  listView1.Items.Clear();

  for (int i = 0; i < dataGridView1.Rows.Count; i++)
  {
    tempIndex = (tempIndex + 1) % dataGridView1.Rows.Count;
    DataGridViewRow row = dataGridView1.Rows[tempIndex];

    if (row.Cells["Foo"].Value == null)
    {
      continue;
    }

    if (row.Cells["Foo"].Value.ToString().Trim().StartsWith(textBox1.Text) || row.Cells["Foo"].Value.ToString().Trim().Contains(textBox1.Text))
    {
      DataGridViewCell cell = row.Cells["Foo"];
      ListViewItem lvRow = new ListViewItem(new string[] { cell.ColumnIndex.ToString(), cell.RowIndex.ToString(), cell.Value.ToString() });
      listView1.Items.Add(lvRow);
    }
  }

  MessageBox.Show("Search ended."); // Or whatever message you intend to send.
}
