When are User Roles Initialized?

[Jonathan Wood]

I've set up ASP.NET membership.

I can get the role(s) of the current user by calling
Roles.GetRolesForUser().

It seems like it would be a good idea to store some role-specific
calculations in the Session object so that I don't need to re-perform these
calculations for each page.

Questions:

1. Does storing data calculated from the current user's role in the Session
object seem like a good approach so I don't need to perform these
calculations again for each page?

2. Where would I do initialize this data? I tried placing code in the
LoggedIn event of my Login control. The problem is that
Roles.GetRolesForUser() seems to return an empty list at this point. I guess
it hasn't been initialized when this event is called. So where else could I
get it?

Thanks.

Jonathan,

1. Yes, it does seem like a good approach.

2. It is a registered problem. It was discussed here
http://groups.google.com/group/micr...ork.aspnet/browse_frm/thread/2e546baadef642cf

Scott Guthrie explained the problem and offered a workaround:
The authentication principal won't get set until the next request to the
web-server. But you can use the "UserName" property on the Usercontrol
within the LoggedIn event to identify the user.

You can then use the Role APIs and pass the user name to retrieve their role
information.
