Problem with Sessions

[dcusick]

Okay... I'm new to ASP.NET. Been programming classic ASP for quite some time, and finally started moving onto .NET.

Anyway, I have a User object. Upon login, using Forms authentication, I authenticate the user and my authentication method returns a User object. So I want to store this object in the session, to use throughout my app. So, I set a session variable to this object.

Viewing the pagestate and trace info, I see that this is indeed in the session. However, after I redirect the user to the main page, I cannot grab the session variable. I try to retrieve it, by casting it into a User object, but all I get is a null value. However, on this main page, in the trace info, I still see this session object.

Any ideas why I cannot retrieve it? I'm using the following code to retrieve it

IUser objUser = (IUser) Session["objUser"];

Thanks in advance for any help...

Don't know if this helps, but when using ASP.NET Forms Authentication, I thought there was a User object created anyway that was accessible through HttpContext.Current.User or Context.User.
Is your User object a custom object or are you trying to save this one into the session?

I think the problem is in the IUser implementation.
Try the two statements to store/retrive objects using a DataTable for example:

// save the object in one page
Session["Customers"]=dtCustomers;

Restore the object in another page:

DataTable dt = Session["Customers"];
