Hi,

Try the following code. The first column can't be an identity or key.

namespace Test
{
    public partial class Form2 : Form
    {
        //default values in the grid
        List<object[]> _values = new List<object[]>();
        DataTable _table = new DataTable();
        DataColumn _seq = new DataColumn("Seq", typeof(System.Int32));
        DataColumn _name = new DataColumn("Name", typeof(System.String));
        public Form2()
        {
            InitializeComponent();

            // add the columns
            _table.Columns.AddRange(new DataColumn[] {_seq, _name });
            //assign values to grid (mis adorados hijos)
            _values.Add(new object[]{"3", "Ale"});
            _values.Add(new object[]{ "5", "Dodi"});
            _values.Add(new object[]{ "7", "Chechar"});

           
            for (int i = 0; i < _values.Count; i++)
            {
                _table.LoadDataRow(_values[i], true);
               
            }
            this.dataGridView1.DataSource = _table;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.dataGridView1.Rows[0].Selected = true;
            int _newvalue = Int32.Parse(this.textBox1.Text);
            int _increment = Int32.Parse(this.textBox2.Text);
            for (int i = 0; i < this.dataGridView1.Rows.Count-1; i++)
            {
                this.dataGridView1.Rows[i].Cells["Seq"].Value = _newvalue;
                _newvalue += _increment;
            }
        }
    }
}

best regards

Thanks thanks...
