Assigning a value to ComboBox Items

I'm currently trying to make a drop box (Combobox) for currencies for a winform. Here's what I have so far:

But I noticed that there is a special option for the Databound version of a drop down box. So I was wondering if it was possible to create something similar to this without resorting to do a comparison against the entire string or creating a table in a database.
