There are many ways of getting an object from another object based on 
name. You can see zopelabs.com or the Zope book for some examples. One 
of the most common (with your context) is::

somevariable = "igrid"
obj = context[somevariable]
obj.setRow(...)

You can imagine how to collapse the last two lines. (I didn't do it for 
illustrative purposes.) Keep in mind that if 'context' doesn't contain 
the thing named by 'somevariable' then you will get a KeyError. You may 
either catch this, check first (has _key), or use another method 
(getattr, restrictedTraverse).
