i think this is what you are looking for protected void GDVDates_RowDataBound(object sender GridViewRowEventArgs e) { if (e.Row.RowIndex e.Row.Cells[3].Text = Convert.ToInt32(e.Row.Cells[1].Text).ToString() +  -  + Convert.ToInt32(e.Row.Cells[2].Text).ToString(); e.Row.Cells[1].Text = Convert.ToInt32(e.Row.Cells[1].Text).ToString(); e.Row.Cells[2].Text = Convert.ToInt32(e.Row.Cells[2].Text).ToString(); }
