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
