As I have stated in a previous reply to you, do not change the
_init_* methods unless you know what you are doing ;)

Luckily there is support already built into Boa to do what you want.

It's called 'custom classes'. The first change you need to make, is to
change your dbGrid class to have the same constructor as the original
wxGrid class.

Then uncomment the line
#        self.grid1 = wxGrid ...

and delete the line you added

          self.grid1 = dbGrid ...

Now add the following _custom_classes line to the top of the wxFrame1 
definition as a class attribute:

class wxFrame1(wxFrame):

    _custom_classes = {'wxGrid': ['dbGrid']}           

    def _init_utils(self):

Now open the Designer, select the Grid and change the Class property
from wxGrid to dbGrid.

You will notice that the constructor you defined takes 1 parameter,
yet it is called with 5 keyword parameters in the source.

I've never really used the grid, sorry.

Good luck!
