View 11 RepliesI am getting this error "The session state information is invalid and might be corrupted " as i hve checked all my session variable initialized with some default value and the existing code works fine in version 1.1 but on conversion it is giving specified error. The error comes when i simply click on a link to redirect to some other page.
View 5 RepliesAfter doing some research, I found that <sessionState> can be hosted in SQL Server allowing applications to read from the same source. Essentially my app has two sides: a WCF library and an ASP.NET MVC 3 web site, the WCF has authentication and other DB IO methods and the MVC does the display. Now, the MVC stores a value in the session and then the WCF reads it and creates another for the MVC to read later. Problem is, neither can read each others session data, they can write to the same repository but can't share.
How do I go about them sharing the same information? How can I tell <sessionState> that the session started on the MVC side is the same as the WCF side and viceversa? I've tried

I am developing ASP.Net Website, using Visual Studio 2008.
I created a class named "BasePage" under "App_Code".

Now, I know if I inherit this class in all of my pages, that will work but I am looking to do this through Config file.
Is there any way that I can write something in Config file to use this class for all the pages?
so that if I want to remove, I can simply remove from config file and I do not need to compile my whole project again.

I need to store a large amount of data in user's session but I guess using Session Object is not the best way of doing that. Is there any other way around??? Remember I don't have small variables to store, I have large collections.

View 2 RepliesI have a aspx page and there is a web user control that must load dynamically with the data related to the aspx page....
ok so I want to use a querystring and pass it to the web user control.....how do I do this?
then also how do I pass a querystring from a web user control back to a aspx page?
This is a question I always had...and therefore never actually started to use the web user control
I've a Linkbutton control in the master page. And in the content page(Home.aspx) i'm trying to navigate it an aspx page(Apply.aspx) passing a value using querystring. Everything is working fine when i click the apply linkbutton control for the first time i.e i'm able to get the value the querystring and able to use it.
But when i click on the same linkbutton second time, i'm not getting the querystring value?how to persist the querystring value on reloading?
We have a web site that implements a custom SiteMapProvider using a User Control added in the master page. I need to be able to limit the sitemap nodes added depending on the logged in user, that is, certain users should not see certain sitemap nodes. Currently, the login processing code determines if users are in the certain category or role and then sets a value in session state, for example, Session["UserInRoleXXX"] = "Yes"; I tried changing the code in the user control to check the session state, but I got the following error: NullReferenceException ... Object reference not set to an instance of an object." Can session state be accessed in a user control?
View 6 Repliesi am working on a web application. i have 10 textbox control, in the page and 6 check box control . i need to store all those values in a session. but storing such a big field value is nothing but to create more session values. but i dont want create more than one session variables. how should i do this.
View 1 RepliesI 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.
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#.
in my application the default time out period for a session is 20 minutes. but i want to increase the sessiion time out period for a textbox.
View 4 RepliesI want to control the login user to access our system. I authenticated all of users by using my own way in project. and I want to limit the number of user to access the system cncurrently. It means , We sell our project to customer as Licence software. If user buy it for three users, we will allow three conurrent login user to access the system. Our system allow our customer to create their own users as they wish. We don't want to control the user creation to use the system. but But we want to control the total no of current login user at the server as per our licence agreement . After reading some article, I see there are two main ways to control the no of users.
One way is to use the membership property in my project and then can count the number of online users by executing Membership.GetNumberOfUsersOnline Method.
If I use membership property, I think it is not ok at my project. As my understanding, the system will control the user creation if we use the memebership provider. I am not really sure whether I can use membership provider property to get my system requirement or not.
