I;m building a new ASP.net application (C# code behind). I'm using the membership framework for security. I built an additonal userinfo table that links back to the aspnetUsers table. The userInfo table contaiins addional data about the user (last name, a differe userid, etc.) When a user logs in I want to grab that data from the database and be able to call it whenever I need to. For example, the page I'm working on now is the default page that loads once the user logs in. I want to display a gridview of data from that table specific to that user. The data is linked to that user by the userid (an int in a SQL Server database table) in the userInfo table. I need to call that userid at various times. How can I call and store that data?
