"where to set the converter for items of a collection in xaml" Code Answer

the problem is that you are trying to convert the entire collection rather than just one item from the collection.

you would want to do something like this:

<listbox itemssource="{binding yearscollection}">
    <listbox.itemtemplate>
        <datatemplate>
             <border datacontext="{binding converter={staticresource inttostringyearconverter}">
             ...
             </border>
        </datatemplate>
    </listbox.itemtemplate>
</listbox>
