Hello! Can someone help me? I need to get the product of the 2 columns in the same row but my problem is the values of my datagridview come from database and the number for rows is not fixed. Thank you very much and God Bless. :)

Hi ....
try this code.........

For i = 0 To TempDataset.Tables(0).Rows.Count - 1
Dim Productvalue As Double = 0
Productvalue = Val(TempDataset.Tables(0).Rows(i)("BillAmount").ToString) * Val(TempDataset.Tables(0).Rows(i)("BillAmount").ToString)
PatientDataGridView.Rows.Add(TempDataset.Tables(0).Rows(i)("PatientID").ToString, TempDataset.Tables(0).Rows(i)("PatientName").ToString, _
TempDataset.Tables(0).Rows(i)("BillAmount").ToString, TempDataset.Tables(0).Rows(i)("Commission").ToString, Productvalue)


May I ask, "BillAmount" is for what? Thanks and God Bless. :)
