Question

I'm new to asp world, and I have to keep my new job :) Switching form php to asp.net 3.5 (never used before). What would be the best practice for storing a SESSION variable in my project ?

How can I prevent my SESSION to be overwritten if my initialisation code is in the onPageLoad method of my MasterPage ?

My variables keeps beeing overwritten, please someone help me and tell me if there is any other solution than dealing with this pageLoad problem.

Answer 1

if(Session["account"] == null) {
Session["account"] = GetAccount();
}

Answer 2

You can always check that if the Session value exists or not.

if(Session["UserName"] == null) 
{
   Session["UserName"] = User.Identity.UserName; 
}

Answer 3

First up, if your session values are getting lost... there must be something wrong. That totally defeats the purpose of having sessions!

You can try a couple of articles and get better understanding of this...
