When I click on the button inside the formview, I get the default event for the FormView and not the button. Maybe there's no hope for this route.

Another option would be to put the button outside of the formview, but I also need access to one of the data fields from the FormView's binding to give the button custom text. How could one do this? using Eval("FieldName"), returns blank so that tells me that it's out of scope
