State Management :: Session Variable Looses Its Value On Next Page?

Jul 23, 2010

IDE: MS Visual Studio 2008 / SQL Server 2005 Express / SQL Server Management Studio Express 2005

Skills: Beginner

Well im trying to make a custom login page(im not using ASP.net Login Control), in Admin.aspx page

UserName and Pasword are entered in textboxes , then Code-Behind file checks the UserName and Pasword against DataBase(it stores the UserName and Pasword) if both are correct Session["IsAuthenticated"] = "true" and then user is redirected to AdminArea.aspx

AdminArea.aspx checks if ( Session["IsAuthenticated"].ToString() == "false" ) then redirect to Error page..

but i get NullReferenceException on AdminArea.aspx because Session["IsAuthenticated"] is null , i dont know why ?

I even tried PreviousPage.Session["IsAuthneticated"] but still got the same error..

I debugged,and found out Admin.aspx saves value in Session["IsAuthenticated"] succesfully but AdminArea.aspx looses the Session["IsAuthenticated"]..so it gets null

My Question is how to retain value in Session["IsAuthenticated"] when page is changed (I want to retrieve value in next page from Session)?

State Management :: Session Variable Disappears When Leaving Page?

May 14, 2010

I have a session variable which contains a list of elements. The user defines filters, which are sent to the Database, which fills the object with the elements that match. Then, that list is shown in a table. The code goes something like this:

[Code]....

Inside that page there is a button, which sends the request given the user filters. The Server creates the object and the session variable is assigned a value.

[Code]....

It works when the user sets the filters. However, given that once done it, the session variable has a value, I don't understand why if you navigate to other pages, the table doesn't appear when you return, given that:

1. It works when you perform the query and reload the page

2. The Session variable should be set for the rest of the session

State Management :: Session Variable And Applying The Master Page Dynamically Using The Page_PreInit Event

Jun 8, 2010

In my web application, I have to load different Master pages depending on the user log-in information. When I say different, I mean not just the colors but a whole new look[including navigation options]. So I am using 2 Master pages [one of them is set as default] and depending on the user information the other page will be used.

I got it to work by storing the user information in a Session variable and applying the master page dynamically using the Page_PreInit event. But the issue is, if I hit the back
button, sometimes [yeah, only sometimes !!!] the master page is reset to the default page. Initially I thought it is a Session timeout issue. But it isn't, as some of the session variables still have data. Can anyone explain whats actually happening?

State Management :: Variable To Store Temporary Page Data?

Sep 29, 2010

I'm working on a web page that is going to be used to enter data into a database. The page is going to be dynamic in that the user has the ability to add a row to the table with the same fields, ie lname1, fname1, mi1 then lname2, fname2, mi2

I'm wanting to use a variable to keep track of how many lines there are so that when I generate the added line I am creating a new field with the ID of lname+# . Whats the best way to do this, a global variable, session variable? As side note, first time programming in .Net or C#.

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.

State Management :: How To Abandon A User's Previous Session

Jun 11, 2010

In my ASP.NET application I need to allow only one session for a user ? When a user does login more than once, I want to get to user's previous session and abandon it. I'm keeping track of all user sessions by means of session id. But Session.Abandon is available only for the current session associated with a request and not previous sessions. I have the session id of the user's previous session but how can I end it ?

State Management :: Create A Session Variable To Pass Some Data Between A Couple Of Pages?

Mar 20, 2011

I searched on this all morning, but I'm still not sure. If I create a session variable to pass some data between a couple of pages, does that variable time out after it reaches the timeout period set on IIS, or will it persist for the entire time the user keeps a session alive? For example, session variable is used shortly after login and then never again. Susy uses other pages for two hours and keeps session active. Did that first session variable die after 20 minutes, or is it still there 2 hours later?

State Management :: Session Variable Authentication State Timeout?

Dec 3, 2010

I am building a web app that is limited to one database, therefore I cannot use the ASP.NET config tool. As a quick means of getting this app online, I tried to use a simple session variable. The login page verifies the user's credentials, and if they pass, it sets the session variable to a certain value. All other pages check in the page_load event whether or not the session variable is equal to that value. The problem is that once being logged in for a short while and sending and recieving some data, the session variable resets, and I'm returned to the login page to repeat the process. Here's the basic code from my webforms:

[code]....

Is there some setting I need to change in the web.config file to adjust the cookie timeout or is that only for the config tool authentication methods?

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.
