Sessions variables getting lost

Hey,
I've spend ages looking into the problem, but I cant find it.

This is my page code

Code:

---

Protected Sub btnLogin_Click(sender As Object, e As EventArgs) Handles btnLogin.Click
            Dim blnLogin As Boolean
        blnLogin = Login(txtUserLogin.Text, txtPassword.Text)

            If blnLogin = True Then
            Session("LoggedIn") = ""
            Session("LoggedInUser") = txtUserLogin.Text
            Session("LoggedInID") = GetUserID(txtUserLogin.Text)
                lblNotice.Text = "Login succeeded: " '& GetFriends(Session("LoggedInUser"))
            Else
                lblNotice.Text = "User not found"
        End If
    End Sub

    Protected Sub btnAddToWall_Click(sender As Object, e As EventArgs) Handles btnAddToWall.Click
        MsgBox(Session("LoggedInID"))
    End Sub

---

So after the user presses the Login button there should be 3 variables stored in a session, this works (checked using trace='true')

Session State
Session Key Type Value
LoggedIn System.String
LoggedInUser System.String User
LoggedInID System.Int32 2

That's fine. Now I click on the AddToWall button to check if I can get the LoggedInID, it shows an empty messagebox.

In the trace there are no Sessions keys left.
How can I make it keep the keys after postback/after clicking on buttons?

Note: When calling GetFriends(Session("LoggedInUser")) in the same sub as the Login button the variable does get passed to the class with sub GetFriends()

Here's my web.config

Code:

---

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
    <sessionState timeout="30" />
  </system.web>

</configuration>

Have you tried getting any other Session data to AddToWall event? are they all blank if you have? your code looks like its all right, but I am pretty new to VB, but it looks like it should be working. The keys should be staying automatically. And it looks like like that data is staying cause you have traced it...Have you tried saving the data in session as something else then passing that in the MsgBoX?

Protected Sub btnAddToWall_Click(sender As Object, e As EventArgs) Handles btnAddToWall.Click

Dim test As Int32 = Session("LoggedInID")
MsgBox(test)

End Sub

just to see if it passes between the subs, worth a try, but other then that, i don't see anything wrong with your code

Are you clearing the session variable in Page_Load event?

Hello,

You may want to guard against things like this by checking the IsNewSession property:

If for some reason the Session is getting recreated, you should be able to detect this, and redirect the user to the log in page.
