Use Session variables in Global.aspx

[kero]

Hi People,

I want to share Session variables through out all the aspx pages including Global.asax. I have tried placing Session variables into the Global.asax page and it doesn't seems to work.

The Session variables should start as empty variables. When a button has been pressed on a particular page it should update the Session variables and Global.asax will compare the variables everytime the user has press a button/refresh a page.

Could this be possible? Can someone help me out here

Thanks

Please post ASP.NET questions to the ASP.NET forum, rather than .NET Technical. Thank you!

Can you please post a small code sample demonstrating the problem you're having?

Hi Phil,

I want to place the following code to Global.asax, but I'm not sure where? I have a one which is smiliar to the following codes in Application_AuthenticateRequest() section.

        If (Session("userNameUpdated") = "true") Then
            ' -- connecting to the database and setting a SQL command.
            Dim myConnection As New SqlConnection(connectionString)

            ' -- Declare SqlCommand variable to be used on different database
            Dim storeProcedure As String
            Dim rolesCommand As SqlCommand
            Dim roleList As New ArrayList

            storeProcedure = "spUserRole '" & Session("Email") & "'"

            Try
                myConnection.Open()  ' -- Connect to the database
                Dim reader As SqlDataReader = rolesCommand.ExecuteReader()

                ' -- Create an array of role names
                Do While reader.Read()
                    roleList.Add(reader("Role"))
                Loop
                reader.Close()

            Catch SQLexc As SqlException
                SQLexc.ToString()

            Catch ex As Exception
                ex.ToString()

            Finally
                myConnection.Close()  ' -- Close to the database

            End Try


            '-- Convert the roleList ArrayList to a String array
            Dim roleListArray As String() = roleList.ToArray(GetType(String))

            Dim myIdentity As New GenericIdentity(Session("Email"))
            HttpContext.Current.User = New GenericPrincipal(myIdentity, roleListArray)
            Session("userNameUpdated") = "false"
        End If

I have used User.Identity in the Application_AuthenticateRequest() instead of Session("EMail"). The Session("userNameUpdated") And Session("EMail") won't work on Application_AuthenticationRequest(). I need to find a way to compare session variables that has been updated or not

Please help

Thanks

Does the code work in Authenticate_Request? What problem are you having?

Hi Phil,

I can't get the session working. I need to check against session when someone update their Username from the update form and press the save button

The code works with out session in AuthenticateRequest part, but as soon as I have placed session in AuthenticateRequest it gives me an errror message saying that session is not available in this context

How do I make a Global variable so I can share with aspx and the Global.asax pages?

Please help

See if this helps: http://dotnet247.com/247reference/msgs/45/227112.aspx

I found it by searching for "asp.net session authenticaterequest not available context".

Thanks Phil,

I will try it out later and let you know does it work. If it doesn't work I will store the updated userName to a temp variable first. When the session ends the userName will be updated to the database.
