why VXFlexGrid version8 cannot work?

Private Sub vsGrd_LeaveCell()
Dim lRow As Long

lRow = vsGrd.Row
vsGrd.CellBackColor = vbWhite
vsGrd.Cell(flexcpFontBold, lRow, 1, lRow, 2) = False

End Sub

Private Sub vsGrd_SelChange()

Dim iSeq As Integer
iSeq = CLng(vsGrd.TextMatrix(lRow, 0))

End Sub

I use this 2 function at last VXFlexGrid version 5 and 6, but after i change to VXFlexGrid 8 then cannot work.

Can anyone help me please?
thank u
