Vista - How do you retrieve the actual value displayed in a ListView/GridView after binding and converting?

Hi!

I'm using a ListView with a GridView and I'm using all sorts of
different bindings and converters when displaying my data. My question
is: how can I retrieve the value that is actually displayed to the
user at a certain grid position (row,column)?

I'm using a DataTemplate as a cell template for my columns and in the
DataTemplate I have a binding to a property on my underlying C# object
and I also have a converter that converts the data of that property.

I can get the underlying bound object but I'm not interested in that.
I want to be able to write unit tests that tests the binding/
conversion mechanism and so I need the "end-result", the actual text
presented to the user. I tried playing around with automation but that
didn't get me anywhere.
