Updating "index" column in datagridview

updating

Hi,

I'm trying to programmatically update my data in a dataGridView1 table. So, but pressing a button I add another row of data and it has an sequential index number (eg 1, 2, 3, 4... etc).

I have also a delete row button which will delete selected rows - what I'm trying to achieve is to update the index value for all the rows so when I delete lets say row 3 it will still count 1, 2, 3, 4 and not 1,2,4,5. Any ideas? The "index" is the line number, hence has to be sequential.


Thanks.

What I have tried:

<pre lang="c#">
        private void buttonDeleteRow_Click(object sender, EventArgs e)
        {
            foreach (DataGridViewRow row in this.dataGridView1.SelectedRows)
            {
                if (!row.IsNewRow)
                { this.dataGridView1.Rows.RemoveAt(row.Index); }
            }
        }
