Activities of "ctesene"

FYI. I found the article below, and it worked perfectly.

I'm running the aspnet core w/ angular 2 solution. I have a RAD generated entity, lets call them "students". On the students list page (auto generated code) there are multiple filters. I have a "student" detail page that we navigate to (not a modal), and when the user hits the back button to get to the student list page, all of the filter criteria is lost.

So far I see there are two options,

1. persist the filter criteria to the query string and reload on load.
2. use some shared state service to store the state

Anyone else have any other ideas?
