I think a good idea is to structure your code so that you work with these values as parameters passed from one context to the other. Maybe right now you read your data from the session state but tomorrow you'll have to read it from the query string or some control on a page. Maybe you'll even find another use for the same piece of code that fills the datasource but you'll be stuck because it's not flexible enough.

So what I suggest is to not attempt to read that value directly from some specific source but expect it as a parameter.

Specific to your current issue, it's normal that you can only access the Session state from the context of the web application itself, not from a distinct library.

You have to pass the values from the session which you need in your library as parameters. Separating gui and logic is always a good idea.
