        {
            string pathconn = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + txt_path.Text + ";extended properties=\"Excel 8.0; HDR=yes;\";";
            OleDbConnection cn = new OleDbConnection(pathconn);
            OleDbDataAdapter adp = new OleDbDataAdapter("select * from[" + txt_sheetname.Text + "$]", cn);
            DataTable dt = new DataTable();
            adp.Fill(dt);

            dataGridView1.DataSource = dt;

            List<DataGridViewRow> rowsToRemove = new List<DataGridViewRow>();

            //foreach (DataGridViewRow row in dataGridView1.Rows)
            //{
            //    if (!row.IsNewRow)
            //    {
            //        if (int.Parse(dataGridView1[1, row.Index].Value.ToString()) == 0)
            //        {
            //            rowsToRemove.Add(row);
            //        }


            //    }
            //}
            //foreach (DataGridViewRow row in rowsToRemove)
            //    dataGridView1.Rows.Remove(row);
            this.dataGridView1.Sort(this.dataGridView1.Columns["Name"], ListSortDirection.Ascending);
        }

Hi Steve,

Thanks for the reply.
I wont wish to eliminate through the excel,
As datagridview's only purpose to display the valid data.

Consider:
1. adding a where clause to the query
2. using a DataView as the DataGrid's DataSource
