I am not sure why, but i cannot seem to add a comment to your question...

My first question would be if you can post the XAML with the datagrid in it?

Second question: Why do you want to have (direct) access to your checkbox? most of the things I can think of are achievable using binding and a good implementation of a viewmodel. Can you elaborate on that?
