Q:

Reading datagridview (table) using pywinauto

I want to do some automation using pywinauto and I'm stuck at reading DataGridView table.  How do I convert it to readable table?  I need to see the actual data in the table.  The columns in the table are dynamic, you can add or remove the one you need.  As far as I understand I need to convert ir using ListViewWrapper but I can't get the element of the table.  The control identifiers:
app = Application(backend='uia').connect(title_re=app_regex)
dgv = app.top_window().DataGridView
dgv.print_control_identifiers()

Table - 'DataGridView'    (L198, T191, R1366, B621)

A:

You may not like the answer, but current situation is not good for your task. 

If you have no access to the app source code, it's impossible to get texts using pywinauto. 
But if you have, it requires to implement so called Server Provider for this control type (described in the UI Automation API docs on MSDN).  Though I never tried this way. 
Another theoretically possible approach should use managed DLL injection to access internal properties of custom .NET controls.  I know TestComplete, Squish and UFT use this way.  But they are all very expensive.  Never heard about any open source tool using this approach. 

P.S. Screen text recognition is also theoretically possible way, but the tools are not mature enough to recognize it reliably.
