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)
View 2 RepliesI have a generic handler in which I fill up a Session variable. I implemented the IRequiresSessionState interface, so it shouldn't be a problem.
In a given page, I want to display that value, but it seems like the value is always empty. Is it because the session that is accessed and written to in the handler isn't the same one that is used on this page?
In the handler, I used context.Session["EID"] = "somevalue";
edit: i found out what the issue is but I do not know how to solve it. It's because I have this Java applet which reads out an eID, calls the handler to store the data, but the session used by the applet is not the same as the session used by the browser... so how could I exchange this data in a safe way?
I created a form where I put some radio buttons. When User select one of them depending upon the option it will start his / her time counter. StartTime and EndTime and I am couting total time he/she takes. Till here it is OK. But what I want when user clicks on Logout, then he/she will logged out (Temporary). and after the some time when he / she will again login..... here, I want to set his / her EndTiming. I don't understand how to maintain this state?
View 5 RepliesI'm building a site (it's amazing how much you can do and still not know what you're doing).I have my visitor login from a login.aspx page and, when authenticated are redirected to a Portal page. On that Portal page at pageload I set a Session variable "UserName" using the User.Identity.Name like this:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If User.Identity.Name <> "" And User.Identity.IsAuthenticated = True Then
If Page.IsPostBack = False Then
Session("UserName") = User.Identity.Name

I have a web application running on IIS 7 on a Windows 7 machine. The app pool is configured for .Net 4, 32 bit enabled, Integrated Pipeline.
Everything seems to be fine with the app until I first create a session variable in one of my asmx pages.
Once I've created the session variable the handling of subsequent http requests sometimes takes upwards of 30 after the browser has posted to my asmx page before the function is actually invoked. I've been looking all over my configuration settings and searching the web and still have no idea what could be going wrong here.
The method that sets the session variable looks something like this:

I am using the "Inproc" mode of setting session state to 45 minutes but still the session times out after 10 or so minutes.

How do I correctly define my boolean expression? I've been looking, but haven't found the right syntax.

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 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 .

View 4 RepliesBy 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)?

View 5 RepliesI 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'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?
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.
<sessionState timeout="120"></sessionState>
<authentication mode="Forms">
<forms name="myappCookie" loginUrl="~/index.aspx" timeout="120"/>
</authentication>
doesn't work for me since i don't have allow or deny settings, since my app doesn't need authentication.
