Hi You can try like this this.dataGridView1.CellEndEdit += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView1_CellEndEdit); private void dataGridView1_CellEndEdit(object sender DataGridViewCellEventArgs e) { int total = 0; var teMark = dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString(); if (teMark != string.Empty) { total = total + Convert.ToInt32(teMark); } var ceMark = dataGridView1.Rows[e.RowIndex].Cells[2].Value.ToString(); if (ceMark != string.Empty) { total = total + Convert.ToInt32(ceMark); } var peMark = dataGridView1.Rows[e.RowIndex].Cells[3].Value.ToString(); if (peMark != string.Empty) { total = total + Convert.ToInt32(peMark); } dataGridView1.Rows[e.RowIndex].Cells[4].Value = total; } Regards Iftikar
