What I want to achieved.

IN MY DGV

COL1	COL2	COL3
ITEM1	1	      1
ITEM2	2	      1
ITEM3	3	      2
ITEM4	4	      2
ITEM5	5	      3
ITEM6	6	      3
ITEM7	7	      4
ITEM8	8	      4
ITEM9	9	      5
ITEM10	10	      5
ITEM11	11	      6
ITEM12	12	      6
ITEM13	13	      7
ITEM14	14	      7

Is there a way to do this stuff? tia

What I have tried:

VB

DGV.Rows(0).Cells(2).Value =1
DGV.Rows(1).Cells(2).VALUE = 1+ DGV.Rows(0).Cells(2).Value
DGV.Rows(2).Cells(2).VALUE = 1+ DGV.Rows(1).Cells(2).Value
DGV.Rows(3).Cells(2).VALUE = 1+ DGV.Rows(2).Cells(2).Value
DGV.Rows(4).Cells(2).VALUE = 1+ DGV.Rows(3).Cells(2).Value
DGV.Rows(5).Cells(2).VALUE = 1+ DGV.Rows(4).Cells(2).Value
DGV.Rows(6).Cells(2).VALUE = 1+ DGV.Rows(5).Cells(2).Value
DGV.Rows(7).Cells(2).VALUE = 1+ DGV.Rows(6).Cells(2).Value
DGV.Rows(8).Cells(2).VALUE = 1+ DGV.Rows(7).Cells(2).Value
DGV.Rows(9).Cells(2).VALUE = 1+ DGV.Rows(8).Cells(2).Value
DGV.Rows(10).Cells(2).VALUE = 1+ DGV.Rows(9).Cells(2).Value
DGV.Rows(11).Cells(2).VALUE = 1+ DGV.Rows(10).Cells(2).Value
DGV.Rows(12).Cells(2).VALUE = 1+ DGV.Rows(11).Cells(2).Value
DGV.Rows(13).Cells(2).VALUE = 1+ DGV.Rows(12).Cells(2).Value
DGV.Rows(14).Cells(2).VALUE = 1+ DGV.Rows(13).Cells(2).Value

Solution 2

A better way would be to use a loop:

For i As Integer = 0 To 14
    DGV.Rows(i).Cells(2).Value = i + 1
Next

But ... since indexes are zero based, the column you want to index is probably 1, not 2

Hi, I tried using your code and also the code of Richard MacCutchan, but seems that it only solves the col2 problem, what should I do to fix my col3 problem?

OriginalGriff 5-Apr-22 4:00am

For i As Integer = 0 To 14
    DGV.Rows(i).Cells(2).Value = i + 1
    DGV.Rows(i).Cells(3).Value = (i + 2) \ 2
Next

it works, but why did you use backslash?
i mean, you divide stuff there, but when i change it to slash, it gives me numbers with .5 values.

"\" is the VB Integer Divide: 4 \ 2 and 5 \ 2 both give 2; 6 \ 2 and 7 \ 2 both give 3; and so on.
