Checkbox as filter

[jkdoyle]

I've seen that this question has been asked before, but there weren't really answers that worked on those post (at least as far as I've seen).  On the datagrid filter extension, there is a great example of how to use a combobox, but what I really need is an extension that filters on a boolean/checkbox. I can't seem to figure this out, and rather than posting my failed examples I would love it if someone could share an example that works.

Thanks!
