Greetings,
I am new to Python...and I am having some difficulty updating a grid
(wx.grid.PyGridTableBase). Everything works just fine (adding
/deleting/ resizing rows, cols) except updating individual cells.

I am using the grids to display data from a database (which is working
fine), I am trying to use the SetValue (as well as self.data[r][c] =
string and others ) method but it does not seem to work. I am at a
lost.

Here is the call to the UpdateRowData function:

self.frame.grid_4.GetTable().UpdateRowData(ndata, ndata[0][0],
len(ndata[0]))

frame id wxFrame
ndata is a list
ndata[0][0] is the row number to update
len(ndata[0]) is the number of columns for the table

Here is the class for your review.

Any help would be most appreciated.
Scott
