View 4 RepliesState Management :: Session Variable Looses Its Value On Next Page?
Jul 23, 2010IDE: 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)?

View 4 RepliesState Management :: Session Variable Disappears When Leaving Page?
May 14, 2010I 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 :: Variable To Store Temporary Page Data?
Sep 29, 2010I'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 :: Session Variable And Applying The Master Page Dynamically Using The Page_PreInit Event
Jun 8, 2010In 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 :: Public Variable Vs Session Variable To Store Logged In UserID
May 17, 2010I 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 :: Session Variable Authentication State Timeout?
Dec 3, 2010I 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 :: Passing Session In Web Service?
Mar 26, 2011I have a number saved in session and am using it in a bunch of pages right now, and I was wondering if I could somehow access this session in my WebService.asmx file? It would be great since then that way I can fix my auto complete extender. I know I can use contextKey, but I am using that contextKey for something else. If session isn't possible in web service, then is it possible to use two contextkeys in auto complete extender, and how?

State Management :: Int Variable Value Not Getting The Stored Value
Mar 17, 2011I have define a variable called number of type int just after the the class definition as follows.
[Code]....
I store a value from a sql query result in the Number variable. ( eg: lets say 23). This gets assigned correctly to theNumber variable. ( checked using a break point)
Then the user does some updates to the web page ( data entry). The web page includes post back events also.
Finally I need to update the webpage in the database. When I do this I see the Number variable has change to 0. ( and not the 23 as in our example). Its always 0 at the time when I update.
I do not do anything for the number variable in the code.

State Management :: Passing Multiple Parameters Value From A Window To Another?
Jul 29, 2010I have a parameter screen which contains many pop up windows for the parameters .
I have a department hierarchy which consists of department , branch and section.
I have 3 pop up windows for each parameter.
When i select, a department, it filters the list of the branch and shows only its branch when i open the branch pop up window.
But the problem is, when i select multiple departments, the branch pop up window shows the below error. The page works if only a department is shown.
Conversion failed when converting the nvarchar value '3,4,5,6 to data type int. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
