            dgvDescription.Columns.Add("description", "Description");
            dgvDescription.Columns.Add("size", "Size");
            dgvDescription.Columns.Add("materialname", "Material Name");

            dgvDescription.Columns.Add("rate", "Rate");
            dgvDescription.Columns.Add("amount", "Amount");
            dgvDescription.Columns.Add("option", "Option");
         
            dgvDescription.Columns[0].Width = 100;
            dgvDescription.Columns[1].Width = 100;
            dgvDescription.Columns[2].Width = 200;
            dgvDescription.Columns[3].Width = 100;
            dgvDescription.Columns[4].Width = 100;
            dgvDescription.Columns[5].Width = 100;
            dgvDescription.Columns[6].Width = 85;
            dgvDescription.Columns[7].Width = 50;
            dgvDescription.Columns[8].Width = 85;
            dgvDescription.Columns[9].Width = 50;
            dgvDescription.Columns[10].Width = 85;
            dgvDescription.Columns[11].Width = 100;
            dgvDescription.Columns[12].Width = 100;                      

            comboQuom.SelectedIndex = 0;
            comboWuom.SelectedIndex = 0;
            this.dgvDescription.Columns["DNO"].Visible = false;
            this.dgvDescription.Columns["SNO"].Visible = false;
            this.dgvDescription.Columns["Option"].Visible = false;

            this.dgvDescription.Columns["qty"].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;
            this.dgvDescription.Columns["weight"].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;
            this.dgvDescription.Columns["rate"].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;
            this.dgvDescription.Columns["amount"].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;

            dgvDeletedescription.Columns.Add("sno", "SNO");
            dgvDeletedescription.Columns.Add("sid", "SID");

            dgvDeletedescription.Columns[0].Width = 100;
            dgvDeletedescription.Columns[0].Width = 100;
