C# - Storing A Collection Into A List And Session - Front End
Jan 29, 2011
I have this program in which I am trying to store a collection of values into a list and session
Example:
valueCollection = (List<Values>)Session["Value"];
I want to do the front end in a way which will show a table with each row showing a label and textbox. This would be too simple to do obviously but I want it to show 4 rows of the table by default and then the user can select "add another" this will then add another row onto the table with a label and textbox exactly similar to the 4 default. Everytime the user selects "add another" the table increments by 1.

I would like to store a collection of strings in the web.config. This collection would vary in size over time. I would like to be able to pull all of the strings in the collection into an array or collection in code. (.Net 4, asp.net)
i.e.
<customCodes>
<VendorCode vendorName="Name1" code="1234567891234567891324567987ddd" isActive="true"/>
<VendorCode vendorName="Name2" code="1sadfsadf1234567891324567987ddd" isActive="true" />
<VendorCode vendorName="Name3" code="123456789dfadfdsaf3324567987d32" isActive="true"/>
</customCodes>
I could use appsettings with the strings all in one value but I would like to seperate it out for organizational reasons. Not using the key/value pair complicates things a bit. I am now getting a message that states "you can't have duplicate elements in a section"

How do you create a dictionary of objects in the session? More specifically, I have a list of objects: MyList stores MyObject as the result of a linq query with the date as a parameter.
List<MyObject> Mylist;
MyList = GetObjects(TheDate);
Now I'd like to store MyList in the session object in a dictionary with the date as the key. When the page needs a MyList for a specific date, first search the dictionary and if it's blank for that date, get the data from the GetObjects query and store the result in the dictionary in the session.

When a use is logged in (Through open-id) we are creating a session variable named "UID" and storing the unique user-id in it. Later we are checking the session to see if the user is logged in. I think this is not the right way, but I could not force the team to change this, as I cannot show how this implementation can be cracked. why (If yes) this implementation is bad?

want to create a list representing a list of valid locations on a grid. Items can only be stored in these valid locations and I want to locate the "next available" valid location. If I do this with a traditional list I have to deal with the end of list conditions. A circular list collection would make this a bit easier. Is there such a collection in .net?

i m developing an application in .NET mvc2. i m using aspnetMembershipProvider for User registration and related activities. i need some custom information about user that i stored in a separate table (sysUser for example) and linked it to aspnetUser table through foreign key. after Login i need to fetch user's credentials from sysUser table and push it to the session. For this Account controller's Logon method seemed best to me and i pasted following code in my Logon ActionResult
[Code]....
The code is working perfectly for me and put my desired information in the session but the thing is that if a user selects Remember me and on his next visit he won't have to Log in and i would not find my desired information in the Session. where should i put my code that stores the user information in the session.

I have created a custom user creation wizard to store custom user information, This is working fine. I am now trying to create a new page to give the newly created user to create users in there own company, so i need to retrieve the company information from the user profile created and automaticlly fill that information into the new create user wizard. ie User from A company logs in. (company_id from profile is stored in session)
User A wants to make another user in company A (but cannot make a user in company B) User A fills in details for new user, Company A information is autofill into new user info. (possibly from session)
I have read alot about storing membership. info into session but i cannot find any code examples of how to do this. I need to find a way to store Company_id into session and then use that for creating a new user with the same Company_id.

Im in the process of developing a web application, and I wish to store a reasonable amount of data for each user.
This data will be accessed each time the page is refreshed.
The only 2 options that I have come up with is:
* Session Data
* Storing the information in a text file with random file names for each person
* Database
The first one I do not really want to use as it would bog down the server - the second one is cumbersome
Is there any other options?
If possible i was thinking using the database, but am hesitant because of the amount of times the accessing of the database would need (every refresh for every user)
I dont want to store the information inside the viewstate (i dont know what MS was thinking when they thought of viewstate)

Is it possible to store gridview session data after each postback. I have a gridview and a checkbox within. Each time a user clicks the checkbox, I like to store the gridview ID in a session. After browsing through various pages, I like this session datato continuously store the information up to 20mins?
How can I continously store the session variable. Say a text box and if I enter 1 click on a hyperlink (where session variable is stored) return back to the page, enter 2 click hyperlink then I should get in the session 12?

I have an ASP.NET web form that has a "container" usercontrol that hosts several custom user controls on the page. The controls can be hosted directly in the container or can be children of other usercontrols. The container usercontrol has several public properties exposed that I sometimes need to get to from within the child user controls. I've been using some form of "this.Parent" or "this.Parent.Parent" to get back to the base control.
What would be the impact of storing a reference to "this" into Session from the base control so I can access it from within the event handlers within the user controls?

I am creating a website that allows users to login to their gameserver remotely and send / receive commands. The connection happens via an UDP socket and requires simply the IP of the gameserver, and a password.
On my website, users can add servers to their accounts, where the server IP and password are stored in a database. Then they can connect to any of their servers, which creates a new Socket object and connects to it using the IP and password of that server.
This Socket object, embedded in an object that also stores the server IP and password, is stored in a Session variable when the user connects, and is retrieved on every page. For example, there's a page where the user can view a list of the players on the server (and kick/ban them), a page with server settings, a page with messages, etc. All these pages require the Socket connection to get their information (they send a certain command and parse the response). When I need to send a command via the socket, I need to send the password of the server each time (otherwise it does not work). My question now is: how secure is this? The password of a server is sensitive information*, but I am storing it in a session variable and sending it (using the Send command of the Socket object) to the server.
i think the Session variable is stored on memory on the server, so I don't think so, but I'm really unsure about these kind of things and I'd like to be certain that my website is secure. Well, I think it will never be 100% secure but I want it to be at least not worth the effort for someone to hack the password. If it takes a lot of trouble then people wouldn't bother, but I don't want to find out that people's passwords are being thrown out on the street (so to speak) and that my website is completely insecure...

I've read that you can store classes directly into a session variable i.e.
Session["var"] = myclass;
My question is how the memory management works. Does it automatically serialize this into the session on the client side?
Or does it hold the data for the instance of the class in server memory, and just holds a reference in the session object?

let us assume that I have a reusable business layer that further makes use of a data access layer that was implemented using Entity Framework 4.0. The entities returned/consumed by the business layer are self-tracking, allowing us all the goodies that come with those type of entities. I would like to be able to store the entities I work with across post backs (on order to avoid re-querying every time). Basically let us assume I have a paged GridView with 10 items in it, and something like a DetailsView to edit those items. Every time you select a new row on the grid, the details view updates with the information of the selected row. My preference would be to only query for the entities on the initial request of the page and store it in session. Then subsequently I have a list of entities that I can work with and eventually modify and send back to the business layer with all of the changes.
I really want to use session instead of view state to reduce the page payload (self tracking entities are heavy) however I really like view state for this because of the fact that when the user navigates away from the page there is no residual effect. Some of the things that worry me are: When a user navigates away from the page to another page, the entities from the previous page are still in session. I could always do something on load of a page to do housekeeping type of work. Not sure if that's good practice. I am worried about people opening browser tabs and having two views into the same page, it seems like that might pose a problem. Is this even a good approach? Seems like I am trying to have the best of all worlds, it would definitely be much easier to simply re-query on every post back for the entities and pay the 50-100ms hit of the database trip.

I'm working with an asp.net application that stores most data in a database and not session. I'm wondering of the pros and cons of each and which is the better way to go. For example, you have a pretty busy site and instead of storing user specific variables in session, there is a DB table called user data and it can store all user specific data that can be accessed from any page by querying the database. Which is the better way to go, session or database?
