Help on how to build checkpoint to compare PB datawindow values row by row

[martinlam]

Dear all,

Please do help on the captioned subject. Thank you very much.

Here is the sample code with ERROR:

Code:

With PbWindow("PbWin1")
   For i = 1 to .PbDataWindow("dw_list").RowCount
      .PbDataWindow("dw_list").SelectCell i,"id"
      For j = 1 to datatable.GetSheet("ChkList").GetRowCount
         datatable.GetSheet("ChkList").SetCurrentRow(j)
         id=DataTable("id", "ChkList")
         If id = parameter("ID") Then
            datatable.GetSheet("ChkList").SetCurrentRow(j+i-1)
            .PbDataWindow("dw_list").Check CheckPoint("ChkList")
            Exit For
         End If
      Next
   Next
End With

DataTable:
Id Value
1 11
1 22
2 33
3 44
3 55

Actually, I want to validate a PBdatawindow or webtable with 3 rows data. I used the aboved code but don't know how to pass the data row by row to checkpoint since the checkpoint will validate 1 row only at once time.
