You are not binding to the Scrollbar.set() method nor are you assigning 
  the Scrollbar a command. You should try to emulate this:

http://www.pythonware.com/library/tkinter/introduction/x7583-patterns.htm

You need to also determine exactly what it is you want to scroll. You 
probably don't want to scroll frame_grid as that contains your 
scrollbar. Google "tkinter scrolled frame". Here is an example:

So, a suggestion would be to create a new frame to hold frame_grid and 
yscroll and then use yscroll to scroll frame_grid.
