Combobox in an ADO datagrid

Hello,

I am a VB6 beginner, and I am looking to use an ADO datagrid with a combobox.  Basically I want to put the combobox on the current datagrid cell so that I can update the grid with a selection from the combo.  The problem I have is this:

I can do it OK with a flexgrid, as follows:

Private Sub MSFlexGrid1_MouseDown(Button As Integer, Shift As Integer, x As Single, y As Single)
Combo1.Visible = False
        Combo1.Left = MSFlexGrid1.Left + MSFlexGrid1.CellLeft
        Combo1.Top = MSFlexGrid1.Top + MSFlexGrid1.CellTop
        Combo1.Width = MSFlexGrid1.CellWidth
        Combo1.Visible = True
End Sub

but I want to use a datagrid because a databound flexgrid is only readonly, and I want to be able to update my database table automatically.  This I can do with a datagrid.  But I can find no way of referencing the datagrid cell in the necessary way.  Help!  Is this impossible with a datagrid???

Alternatively, does anyone know a freeware grid with the above capabilities (ie databinding and cell referencing).

Many thanks,
