Receiving error about enableSessionState; Its already set to true

[Guest]

I keep getting this error.
"Session state can only be used when enableSessionState is set to true,
either in a configuration file or in the Page directive"

This occurs when I try to add a session variable.
....
Session.Add("Nameplate", 1)
....

That is in a button click event.

I've seen many forum entries about this but no suggestions seem to work. I
could use some more leads.

Thanks,

Sean

Sean,
If you look at the error message, you can glean that maybe session state
isn't enabled on your page. Do you have EnableSessionState="true" in your
@Page directive? Is EnableSessionState false in your web.config file? If
you can post a page and web.config file, then the problem can be diagnosed.

Another test to use:
Comment out your Session.Add() line and enter Trace.Warn(EnableSessionState)
Then look at your trace content to see if you get true or false. If you are
unfamiliar with Trace, you can use Response.Write(EnableSessionState) to get
the value.

Best regards,

Jeffrey,
Thanks for a response.

I have already tried to force EnableSessionState=true in the page directive
of the two pages. Also in web.config it looks like

<sessionState
mode="InProc"
cookieless="false"
timeout="20"
EnableSessionState="True"
/>

I tried to put in Response.Write(EnableSessionState) but enablesessionstate
is not a recognized object. Keep in mind this is in the VB file that is a
"Code Behind", should it matter.

Thanks,

Sean

Sean,
This problem has happened to some others (try pasting the error message
in a google groups search). Delete the IIS application and recreate a new
virtual directory in IIS. Set it as an application, and then put your VS
project in this new IIS directory. That has fixed the problem for some
others. It's not a code problem.
