Hi,

1. Declare Datatable as a global variable
2. Create datatabele columns in the Form Load event
3. Add a new Data row and Binding it to the grid.

Please let me know is this you requested...
C#
namespace WFDS
{
    public partial class Form1 : Form
    {
        DataTable dt = new DataTable();
        int i = 0;
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {

            i++;
            DataRow dr = dt.NewRow();

            dr["IEC Parameter Name"] = "Data" + i.ToString();
            dr["Modbus Address"] = "Data" + i.ToString();
            dr["Variable Type"] = "Data" + i.ToString();
            dr["Variable Description"] = "Data" + i.ToString();
            dt.Rows.Add(dr);
            dataGridView1.DataSource = dt;
        }






        private void Form1_Load(object sender, EventArgs e)
        {

            dt.Columns.Add("IEC Parameter Name");
            dt.Columns.Add("Modbus Address");
            dt.Columns.Add("Variable Type");
            dt.Columns.Add("Variable Description");


        }
    }
}
