Answer 1

You can use the DataGridView.RowCount Property.

In this example, this property is used to track the number of entries in a DataGridView

Answer 2

You can display Text in grid view header like following.

private void dataGridView_RowValidated(object sender, DataGridViewCellEventArgs e)
{
    DataGridView gridView = sender as DataGridView;

    if (gridview !=null)
    {
        gridView.Rows[0].HeaderCell.Value = string.format("Total Number of Rows:  {0}",gridview .Rows.Count);
    }
}
