I am using ASP.net for developing an intranet website. I need to hold the userid across all postbacks for all the pages in the website. Is it advisable to hold those information in Session or somether way is available.
If using Forms Authentication, then the username will be available as:
Page.User.Identity.Username
If you need to hold another piece of information alongisde this, then use Session.
PS. I recommend using a class to wrap your session variables for strong-typedness and potential default values.
