当我向我的单元格提交一个值时,这可以正常工作,但是当我向另一个单元格提交另一个值时,它会同时更改这些单元格的值。我不希望它这样做,每个单元格都应该有自己独特的价值,我该怎么做:

       private void retrieveData()
    {
        //returns values, creates and populates dgv
        try
        {
            string company, GetPartCodeV, logname, area;
            dgvDetials.DataSource = null; //resets dgv source to nothing so when refreshing no old data is contained
            dgvDetials.ColumnCount = 0; //removes all columns from dgv so none are repeated when refreshed


            logname = dtArea.Rows[cbArea.SelectedIndex]["logname"].ToString();

            dtArea3 = SQLMethods.GetAreaValues(logname);
            company = dtArea3.Rows[0]["company"].ToString();
            GetPartCodeV = dtArea3.Rows[0]["def_part_type"].ToString();

            DataTable dtGetPartDetails = SQLMethods.PartNo(company, GetPartCodeV); //gets production figures based on selected values

              dgvDetials.DataSource = dtGetPartDetails; //sets dgv source
          //  DataGridViewComboBoxColumn machCol = new DataGridViewComboBoxColumn(); //creates new combobox column for machine
          //  machCol.Name = "machine";
          //  machCol.DataSource = new string[] { "", "1", "2", "3", "4" }; //sets source for combobox column
          //  dgvDetials.Columns.Add(machCol); //adds machine column

            DataGridViewColumn qtyInsp = new DataGridViewColumn(); //creates new textbox column for quantity
            DataGridViewCell qtyCell = new DataGridViewTextBoxCell();
            qtyInsp.CellTemplate = qtyCell;
            qtyInsp.Name = "qty_insp";
            dgvDetials.Columns.Add(qtyInsp); //inserts new column into dgv

            DataGridViewColumn colScrapCount = new DataGridViewColumn(); //creates new textbow column for scrap count
            DataGridViewCell cellScrapCount = new DataGridViewTextBoxCell();
            colScrapCount.CellTemplate = cellScrapCount;
            colScrapCount.Name = "scrapCount";
            dgvDetials.Columns.Add(colScrapCount); //inserts new column

            DataGridViewColumn colReworkCount = new DataGridViewColumn(); //creates new textbox column for rework count
            DataGridViewCell cellReworkCount = new DataGridViewTextBoxCell();
            colReworkCount.CellTemplate = cellReworkCount;
            colReworkCount.Name = "reworkCount";
            dgvDetials.Columns.Add(colReworkCount); //inserts new column into dgv
            dtArea2 = SQLMethods.GetAreaCode(username,logname);
            area = dtArea2.Rows[0]["area_code"].ToString();

            DataGridViewColumn qtyrecorded = new DataGridViewColumn(); //creates new textbox column for quantity
            DataGridViewCell qtyRecCell = new DataGridViewTextBoxCell();
