Session Variable Getting Lost?

Sep 22, 2010

Given this Global.asax.cs:

using System;
using System.Web;

namespace Foo.Web {
[code]....

User hits webapp and is shown Introduction.aspx

User continues using webapp for a few minutes (ASP.NET_SessionId: ublbhu45ji31e055ywqu0555)

User falls idle (doesn't perform any postbacks) for a few minutes

User performs postback

User is shown Introduction.aspx
Second inspection of user's ASP.NET_SessionId cookie still shows ublbhu45ji31e055ywqu0555

Why is the user shown Introduction.apsx the second time inside the same ASP.NET Session? I'm familiar w/ the risk in setting session variables just before a redirect in the same postback, but that doesn't apply here, right?

Session Variable Getting Lost Using Firefox - Works In IE?

Apr 29, 2010

I am setting a Session variable in an HttpHandler, and then getting its value in the Page_load event of an ASPX page. I'm setting it using

public void ProcessRequest(HttpContext context)
{
HttpPostedFile file = context.Request.Files["Filedata"];
context.Session["WorkingImage"] = file.FileName;
}

(And before someone suggests that I check the validity of file.FileName, this same problem occurs if I hard-code a test string in there.) It's working just fine in IE, but in Firefox the Session Variable is not found, getting the "Object reference not set to an instance of an object" error in the following code:

protected void Page_Load(object sender, EventArgs e)
{
string loc = Session["WorkingImage"].ToString();
}

Has anyone encountered this problem - and hopefully come up with a means for passing the session variable?

How To Store A Value Into A Session Variable And Load From That Value Back From The Session Variable

Nov 22, 2010

Currently in an .aspx file, I am storing a value (filename that was created in that session) in an hidden text box. When the user clicks on the "Print" labeled Hyperlink control, it opens the file that was stored in the hidden text box control. But when the user goes to different screen (in the same session), I loose the filename value that is stored in the hidden text box control. So I would like to store the filename variable in a session variable. So that if the user leaves this .aspx file and comes back to this .aspx file I can load the value into the hidden text box from the session variable.

State Management :: Public Variable Vs Session Variable To Store Logged In UserID

May 17, 2010

I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.

I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.

I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.

C# - Viewstate Variable Lost On User Control Loaded Dynamically

Feb 12, 2010

I have a problem with ViewState. I have an aspx page that has a treeview on the left and an UpdatePanel with an ASP.NET Panel inside on the right. It is in that inner Panel where I load and unload dynamically user controls. I use that update panel to load dynamically controls.

I also made a custom control for my user controls because I need to pass some values from page. On that constructor I use ViewState to store these values.

The first time I load the user control I call its constructor with parameters. When I reload that user control on each postback I use its normal constructor.

My problem is I the values I've stored on ViewState has become null on successive postback.

Update:

This is a piece of my user control:

public class MyUserControl : System.Web.UI.UserControl
{
private int PKId
{
get { return ViewState["pkId"] as int; }
set { ViewState["pkId"] = value; }
}
public MyUserControl(int pkId)
{
this.PKId = pkId;
}
...
}

I'm following this article to load controls dynamically: http://msdn.microsoft.com/en-us/magazine/cc748662.aspx#id0070065.

Second Update:
I also set the same control ID when I load the user control at first time and on each reaload.

Maybe I can use another method to store these values like input hidden fields or Cache. I've choosen ViewState because I don't want to overload server with Session values for each user.

Third update:

I load the controls with this code:

System.Web.UI.UserControl baseControl = LoadControl(ucUrl) as System.Web.UI.UserControl;
if (baseControl != null)
{
baseControl.ID = "DestinationUserControl";
PanelDestination.Controls.Add(baseControl);
}

And reaload with this code:

DynamicControls.CreateDestination ud = this.LoadControl(TrackedUserControl) as DynamicControls.CreateDestination;
if (ud != null)
{
ud.ID = "DestinationUserControl";
PanelDestination.Controls.Add(ud);
}

State Management :: Global.asax To Load Up Several Session Variable When A Session Starts?

Sep 14, 2010

I added the following code to global.asax to load up several session variable when a session starts. I'm assuming that when a page goes to use the variable that I should be

1) checking at the page level that the value is valid not 0 when its not expected to be 0, not a zero-length string when its expected to have a length

2) have code at the page level that sets the values if the values have not been set as when the Session timeout, ideally putting the code in a class derived from Page and then deriving all of my pages from the new class so that the code does not have to be repeated in every page

State Management :: Session Variable Persisting Even After Abandoning A Session - Closing Browser Windows

Aug 5, 2010

I have been spending a better part of a week trying to track down why I am not able to clear all session variables in a web app (vs 2010, vb.net). What I have tracked it down to is that when I remove or abandon sessions that my html pages or codebehind access, it works, but for some reason in any of my class files where I use "Public Shared strConnection as String = HttpContext.Current.Session("strConnection").ToString" to access a session variable, it finds the old one and not the current one. I have to wait for it to time out, go in again, and it will find the new one.

I do not use Linq, and there is only one place in the whole web app that I place the connection string in a variable whcih is when a person logs in. It points them to the correct database. The sqlconnection is set for all of my listviews in Page_Init to make sure that they aren't using any session variable that they create on their own. Interestingly enough that if I use debug to go in each time, exit debug, enter debug again trying to access a different database, it works correct each time. I assume that debug is correctly killing the session variable for the classes for me.

//.....
Session["EMPLOYEELOGGEDIN"] = "Y";
//.....
}

Now say i close the browser... and next time when i open the site it takes me directly to the default page [Login_LoggedIn is not called accordingly]... because i'm already logged in for 30 mins acc. to configuration. but as my session id gets changed i can't access Session["EMPLOYEELOGGEDIN"] from any page in this time. It always returns null. But how do i get back the previous session for that person?

Session Variables Lost On Postback Using AJAX?

Jun 7, 2010

I'm evaluating using Ajax in a new project and so I've developed a simple web page to test a few things, however even the simplest task seems to cause my session to be cleared. I am using VS2008 with .Net 3.5 SP1 and the page is in my existing solution which has several custom handlers and modules in the web.config. Below is the code I'm using, it's a simple test which puts a variable into the session then on the buttons postback tries to get the same variable, however it always fails as the session is blank.

The Default.aspx code snippet
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" /> [code]....

Session State Lost Between Ajax Posts?

Jul 16, 2010

I have an asp.net login page, which when initialized sets some session variables. When the user clicks login, an AJAX request is made which validates the user and sets additional session variables and returns a result to the client. The client is then redirected based on the login result. In the redirected page, I can access the session variables set when the login page was initialized (i.e. before the login) but none are present for those set during the login validation (part of an ajax call).

is this expected behaviour? Why would an ajax call generate a new session and thus cause the data to be lost?
