my web app doesn't use authorization in web.config, but i want to detect when a session has expired and redirect to the home page.I have searched and found solutions that rely on the web app using authorization. Other solutions have implemented a user control to drop in every page.Obviosly i don't want to manually check for null on every session variable on every event of the web app, so i want the app to do it automatically.

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)?
How can I remove or Dispose a session once user navigate from one page to other. I just want to use a session which should expire when user navigate to other page..its same like view state..we don't get viewstate information on page to page. why session: i need to keep one value on page constant on page refresh where as Viewstate will be reset to null on page refresh...and i just don't want to use that session once user navigate to other pages.. where i need to plcae the session dispose in page events or methods?..or is there any way to keep viewstate on page refresh?
I have logged in to the application and naviagate to Resource Editor page where it allows user to enter the value and saves to the resource file of the application.
After user clicks save button and navigate to different page the session value becomes null.
If the user navigate to different page without clicking save the session variable has its value
I have a report parameter page which contains many pop up windows for the parameter selection. For example, for driver , there is a pop up window called driver.aspx which contains a listbox that contains list of driver's name.
Now, for each of these pop up windows, i am passing the values of these windows as a session value.
Now, when a user logs in the system, there are many parameter pages for different reports which commonly share the same pop up windows if the parameters are same for different reports.
The problem now is,a user selects 10 drivers for report 1 and runs it. When he goes to report 2 and runs the report, the report 2 takes only those 10 drivers as the driver parameter value.
It means, the error can arise on the system because he may forgot that he have selected 10 drivers for previous report 1. User will not have time to recheck each previous selected values of different paramaters.
What i want is, when a person moves from one report page to another, i want to clear all the session values and adjust it as default for the new report .

Im trying to use code provide in this link below.http://www.codeproject.com/KB/aspnet/MultipleTabWindows.aspxim trying to have the below code in my master page instead of adding to each page. it works if i add to each page, but when i add to ,master page the session value for "WindowName" is always null.how can i fix this?
I read the solutioin for this error, at the following link :http://forums.asp.net/p/1046935/1576341.aspxbut I am still not clear what exactly causes the error. I have two doubts :1. Can anyone please elaborate a bit on this issue, with any example ????2. Is there any drawback of this approach ?
By default when the Session ends then the End-User should be directs to the login page and logs in again. Is there any way to open the login page in a new page rather than opening it in the same page(upon Session time out)?
I'm using sessions to track user name. I assign Session["userName"] in my login procedure. The sessionn gets timeout in about 15 minutes. What I need to do is, if the session timeouts I need to redirect the page to the Default.aspx page.
How can I do this? Any code example would be great.
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
I have developed a project including many pages. But the initial page is HTML , not an aspx page. I want to set the session("language") at this page first. (user can change the language later in the forms)
I'm using the beta version of Visual Studio 2010. I'm running my ASP.NET 4.0 website through the debugger. Whenever there is a page load (e.g. clicking on a link, a postback) the session is ended and a new session is created. This wipes out all the session variables and makes debugging impossible. How to get session variables to persist across page loads?
Is this problem unique to running ASP.NET in a test environment or unique to the beta 2 version of VS 2010?
Ive created an object and placed it in the session, then in my .ashx handler I want to get that object from the session. The problem is that its always null !
heres how ive placed the object into the session from an aspx page
I'm trying to set session variables in one page, and retrieve them in my code file in the page that it posts to.
I keep getting this error. I put the correct namespaces in, and enabledSessionState = true to my application files, but no luck.
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.
I'm just calling a session variable, and I get that error
e.g,
Public AUID As Integer = Convert.ToInt16(Session("AUID"))
