You need to look into how to use custom_classes, this works well for 
your problem as the standard wx.grid is a widget supported by Boa.

Manually insert the custom_classes line, something like this:

class dialogCuvee(wx.Dialog):
     _custom_classes = {'wx.ListCtrl': ['CuveeAllLC'],
                        'wx.grid.Grid': ['CuveeTableGrid'],}
     def _init_coll_bsPage_Items(self, parent):
         # generated method, don't edit


Above shows two custom classes of mine, one is based on wx.ListCtrl and 
the other on a PyGridTableBase.

When you want to place the grid, select it normally from the widget tool 
bar, then in the inspector you will be able to select to either use the 
normal grid or the CuveeTableGrid (in my case).

You then have within the same module the following:

class CuveeDataTable(wx.grid.PyGridTableBase):
     """Grid table base for the cuvee
     """
     def __init__(self, parent):
         wx.grid.PyGridTableBase.__init__(self)
.....etc

class CuveeTableGrid(wx.grid.Grid): #, wxGridAutoEditMixin):
     def __init__(self, parent, id, name, pos, size, style):
         wx.grid.Grid.__init__(self, parent, -1, size=(-1, -1), 
style=wx.DOUBLE_BORDER)
         #wx.GridAutoEditMixin.__init__(self)
.....etc
         self.parent = parent
         self.table = CuveeDataTable(parent=self)

If you write it genericaly (which I did not for my CuveeTableGrid (as I 
only use it in one place so far), then you would place it in a separate 
file and import it using this format:

from listctrlvirtv3 import *

I.e. you can not use "import listctrlvirtv3" as custom_class does not 
support having something like "{'wx.ListCtrl': 
['listctrlvirtv3CuveeAllLC'],"

Hope this gets you going.
