MSHflexgrid alignment

hi friends I want to align my mshflexgrid to center;I tried

Private Sub Form_Load()
Dim i As Integer
For i = 1 To MSHFlexGrid1.Rows - 1
MSHFlexGrid1.CellAlignment = flexAlignCenterCenter
Next i
End Sub

but nothing happend ,what's wrong?

Cell based properties (such as CellAlignment) only affect the currently selected cell(s), as specified by .Row/.Col (and .RowSel/.Colsel).

If you want to change the alignment of cells in an entire column, use .ColAlignment

For a 'random' range of cells, specify .Row/.Col (and .RowSel/.Colsel) as apt, and use .CellAlignment.

thank u ,im gonna try what you said
