Session State issues

[dashen]

I am trying to set up a session state so that I can pass a uniqueid and variables cleanly through an online application. I am having troubles setting up the Session State (I can't even find the information I need in the Assembly names for 2.0). I might just have to use querystrings, but that is a little more unsecure. Can anyone help me with this? Am I looking in the wrong area to find the Session Sate information? Is there a DLL or EXE file that must be run, and if so, do I only set that part up on the server level? Thanks in advance for any help.

session is part of the httpcontext. this is a sealed class and only exists within the context of a web request.

so if you are using Global.asax, a webform (aspx), web user control (ascx), master (.master) page or custom http handler IHttpHandler) you can get to the context which will give you access to session.

Session.Add("YourVariable", value)

To get the value
Somevar = Session.Item("YourVariable")

If you aren't in context (such as a .cs page that isn't code behind), use HttpContext.Current.Session to set your variables.

I tried to use Session.Add and Session.Item and I got nothing

How?

session can be active or deactive to help conserve memory. by default it's on. this value can be set via web.config, at page level or in code.

here is a sample of how session works

public class WebForm1: Page
{
   protected void OnLoad(EventArgs e)
   {
      Session["foo"] = 1;
   }
}

<a href="WebForm2.aspx">Webform 2</a>

public class WebForm2: Page
{
   protected void OnLoad(EventArgs e)
   {
      MyLabel.Text = Session["foo"];
   }
}

<asp:Label id="MyLabel" runat="server" />

I am running a code behind in VB and on an action I do Session add, on another page I tried to access it with Session.Item

Maybe you could supply the complete example you have created to to test this so we don;t have to guess at what you may or may not be doing?

Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click
        Session.Add("myid", "1234567890")
        Response.Redirect("mypage.aspx")
End Sub

On another page

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Label1.Text = Session.Item("myid").ToString
End Sub

I even set the web.config

<sessionState mode="InProc"
					  cookieless="true"
					  regenerateExpiredSessionId="true"
					  timeout="30"
					  sqlConnectionString="Data Source=myserver;Integrated Security=SSPI;"
					  stateNetworkTimeout="30"/>

Figured it out. Haha... you wouldn't believe the problem. I had validation controls in the page and it was halting my action process. I just didn't realize because the validations were at the bottom of the page. So I unflag CausesValidation and it works now. Thanks for the input everyone.
