Problem with filter of a recordset

I converted a program from vb6 to vb.net, I used a propertybag to clone my recordsets and after I would filter them to navigate threw my data
and then show the result in a gridview, but I have a problem in vb.net with my filter.
In vb6 the program would go through my data, but in .net it stays on the same data and it goes into an infinite loop

My problem is to arrange my filter so that it can navigate through my data and change by itself

        Dim intRow As Short
        Dim recRecord As New ADODB.Recordset

        blnReturn = True

        'add the text to put in the tree
        grdCompte.AddItem(NullString)
        intRow = grdCompte.Rows - 1

        If rrecRecord.Fields("Header").Value = 1 Then

            'This line is a header
            grdCompte.set_IsSubtotal(intRow, True)

            'Indicate the indentation of the line
            grdCompte.set_RowOutlineLevel(intRow, vintOutlineLevel)
            grdCompte.Cell(VSFlex7.CellPropertySettings.flexcpFontBold, intRow, 0, , grdCompte.Cols - 1) = True

        Else
            'do nothing
        End If

        'Feed the line with values
        grdCompte.TextMatrix(intRow, mintGRDCompte_col) = (rrecRecord.Fields("Description").Value


        If rrecRecord.Fields("Header").Value = 1 Then
            Call CloneRecordSet(rrecRecord, recRecord)

            'Look if it's parent with other accounts. Then add those accounts.
            recRecord.Filter = NullString

'My problem is here, my value stays the same while in vb6 it was automatically changing
            recRecord.Filter = "ID_Parent=" & rrecRecord.Fields("ID").Value


            Do While Not recRecord.EOF
                Call GRD_AddLine(recRecord, intOutlineLevel + 1)
                recRecord.MoveNext()
