Complete Error
Message:
Session state can only be used
when enableSessionState is set to true, either in a configuration file or in
the Page directive. Please also make sure that System.Web.SessionStateModule or
a custom session state module is included in the <configuration>\<system.web>\<httpModules>
section in the application configuration.
Before
you start your troubleshooting, make sure that the State Service service
application is running. How you will check this?
-Open your Central Administration
-Manage service applications
- check the service application by the name ‘state
service service application’
