datagridview calculation

I'm triying to calculate the datagridview in the attachment by this code:

Code:

---

Dim PAEasayuk1 As Double 
        Dim PAEasayuk2 As Double
        Dim PAEasayuk As Double
     

        For PAEasa1 As Integer = 0 To DataGridView1.RowCount - 1
            For PAEasa2 As Integer = 1 To DataGridView1.RowCount - 1
                For PAEasa3 As Integer = 1 To DataGridView1.RowCount - 1

                    PAEasayuk1 = DataGridView1.Rows(PAEasa1).Cells(0).Value
                    PAEasayuk2 = DataGridView1.Rows(PAEasa2).Cells(1).Value

                    If PAEasayuk2 > PAEasayuk1 Then PAEasayuk = 1 Else PAEasayuk = -1

                    DataGridView1.Rows(PAEasa3).Cells(1).Value = PAEasayuk

                Next
            Next

        Next

End of calculation all results are 1 or -1 . But, I want if it is big 1, otherwise -1
Thanks for the answers.

If I understand what you are trying to do correctly, I think you only need the one loop. See if you understand the following. If not, post back with more information.

Code:

---

Dim PAEasayuk1 As Double
Dim PAEasayuk2 As Double
Dim PAEasayuk As Double


For PAEasa1 As Integer = 0 To DataGridView1.RowCount - 2
    Dim PAEasa2 As Integer = PAEasa1 + 1

    PAEasayuk1 = DataGridView1.Rows(PAEasa1).Cells(0).Value
    PAEasayuk2 = DataGridView1.Rows(PAEasa2).Cells(1).Value

    If PAEasayuk2 > PAEasayuk1 Then PAEasayuk = 1 Else PAEasayuk = -1

    DataGridView1.Rows(PAEasa2).Cells(2).Value = PAEasayuk

Next

Worked very well. Thank you very much.

Last week, I asked "datagridview average calculation" question and didn't get a suitable answer.
If it is not waste of time for you, can you look this thread and examine?

Thank you so much.
