Session object

I'm having this problem of passing session object. When i move from one hyperlink to another, my session object becomes empty.
say:
in page1.aspx
Session("isValid") = True

and when i clicked on the hyperlink
<a href=page2.aspx></a>

it still goes to page2 but I can't get the value of Session("isValid"), when i try to trace it, it is empty.

I've tried using response.redirect, but still the same prob.

so, how can i pass session around the pages?

:confused:

In your web.config file, there should be a tag with an attribute that lets you turn on/off session state management. Make sure this switch isn't set to false.

I've check, It is on....
I'm totally confused....

post your code if you don't mind...i too have been working with session objects recently and have had good luck passing and retaining values...

Ooogs

Try to use relative path e.g. ./ and ../

I started with the login page where user enter password and id, this is how i set the session object if the user exist.

Dim objComm As New SqlCommand(strSQL, objConn) ' Reserve space in memory 'for the SqlCommand object
Dim objReader As SqlDataReader
Try
objConn.Open()
objReader = objComm.ExecuteReader()
If objReader.Read() = False Then
Session("Invalid") = "True"
Return False

Else
Session("Invalid") = ""
Session("LoggedIn") = "True"
Session("UserID") = objReader.Item("UserID").ToString
Session("Category") = objReader.Item("Mem_Category").ToString
Return True
End If
Finally
End Try
objReader.Close()
objConn.Close()

Then, i transfer the user to different page according to their member category by using server.transfer.

server.transfer("Member.aspx")

in Member.aspx page, I still manage to retrieve all info in the Session object, including session("userID").

but when i clicked on a hyperlink that link to another page, it show error that object reference not set to an instance of object in this line of code

" dim str
str= session("UserID")"

btw, the hyperlink is inside a user control, does it matter?
