i have a list of fields that i would store for all the user session. I thought to create a class, insert the information in it and store the class in the session but i'm not sure this is the best way to do it (performances, etc). I should have a list of these informations that i can display in views, i can delete and i can update. How could i do this?
View 10 RepliesIam building a website and i need to store somehow some informations that i will use in the whole site depending of the user type logged in.
Example:
1) User XPTO logs in
2) Query DataBase to see where he belongs
3) Store those 2 or 3 fields that i will get in Database in a persistent way to use it in the whole site.
Whats the best practices to do this?

View 1 RepliesIt has been a while since I've built an entire ASP.NET web application from the ground up but I'm about to jump in again. I've built many individual pages, controls, web parts, etc. recently, but nothting 'soup to nuts' for a couple of years. My question is in regards to login security control. I do not want to use the built in ASP.NET Memberhip functionality for various reasons and already have custom code that authenticates the user, controls passwords, login attempts, etc. I am really concerned though about how to validate that the user is logged in (and the best way to do it). For instance, right now I use a Base page that all of my .aspx pages inherit from. In the OnInit() method, it executes code which includes:
[Code]....
I set the Session["LoggedIn"] object to "true" after the user has successfully been authenticated at the Login.aspx page. So, when a user attempts to access any page in the application, if that Session object isn't true, they will be redirected (you can't visit any page without being logged in). This all works great, but I'm thinking I need something more and that brings me here. First, do I need more? Is this enough? I was thinking about creating a cookie with a GUID value and the SessionID (both encrypted perhaps?) and adding that to my Base page so it checks both the current Session["LoggedIn"] value
and the values in the cookie.
Which is best option to store confidential information in a page?Control,Session,QueryString etc ... ?And also the performance also should be good ... ?
View 11 RepliesWhat is the best way to keep track of user specific information?
I want to show information in querys etc based upon specific properties, for instance a users belongs to a dealer, and that dealer has an ID.
So is it a good way to store that dealer ID in a session variable or should I consider a other option to use this on multiple pages.
i have this form, that the data is stored in a SQL db using Linq.
my question is, how can i add a column, that will have all the information about the sender, meaning IP address, browser, referrer etc.
the thing is is i want to store it in one field. i come from a php knowledge that has been long forgotten by me, but i still remember there was some serialize command, that you could run on an array and store it in a db, then when you want it back to an array you would just run deserialize command and it would go back to an array.
I need to know how to change aspnetdb to store profile information unique to each user so that I can restrict records in an sql table to only show that user's records.
So if I make a "companyID" int, identity column where would I put it?
Also, when I write the where clause to companyID = profile (companyID) would that work?
When a user logins, I want to be able to store all his profile information so I can display, for example, his email on different pages of my website, but I don't want to have to keep querying the database for every time I want to display his email. How would I go about doing this?

View 3 RepliesIs there a way to set a persistent session that would not expire when closing/re-opening a browser. The cookie that is used to store the session_id expires when the browser is closed.
I know we can make the Auth persistent (stay logged in when we close and re-open a browser). In this case, the cookie does NOT expire when the browser is closed
I try to create a persistent cookie to store a preferred language on our website, but it doesn't work.
So, to isolate the problem, I created a new website, with a blank page and with the code behind bellow. If I click the button, the page post back and I get this:
"Cookies expires: 0001-01-01 00:00:00 value: 10"

Its related to datatable in gridview store in session and then session retrive and store to database. basically i am using gridview here creating new row for button click and these row adding untill user's last entry then submit all these entry to database. so i want to use session variable to store this data temporarily and after final entry user click on submit button and all data shold be save in db.
View 9 Repliesi 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.
When the user logs in, I want to store his userID in the session with
HttpContext.Current.Session["UserID"] = 2354; (this is just a hard-coded example)
Then, when I run a page method, if I do
var test = HttpContext.Current.Session["UserID"];
will the variable test hold the value I stored when he logged in?
If this is a correct way of doing it, how do I access the session when I receive a call from a page method? I want to put the test =... line in a page method to identify which user the request is coming from.
How can I use session variable to display user information after authenticated login like Address: 37, kings Road. Position: Secretary base on User ID
View 2 RepliesI'm am building an web application that needs to be able to scale.We want to store, an connection string, an object that says what organization the user is working on right now and the identity of the user.
We could serialize down this and send through the userdata property in the FormsAuthenticationTicket, but that feels to not be the optimal solution, cause its is 4-5 strings of data that is unncessesary, but the main issue is that we are sending an encrypted connectionstring to the user which we dosent want to.
So what are our options?Can ASP.NET Cache be our solution?, can we couple the expiration of the asp.net cache and the formsauthenticationcookie?
I am using Visual Studio 2008.
I created a New Project ASP.NET Web Application.
I created a Textbox named VisitorName. The visitor puts in their name and it goes in VisitorName.Text
There is a Label that says "Which do you own?"
There is a RadioButtonList. It has Cat, Dog and None.
There is a button that says Add to list.
The button needs to add the results of the above items and put them in the list.
Now you keep adding people and their pets.
Once there are all entered you press send and I get the results for everyone entered during that session via email.
I have no database access and the information does not need to be stored in such a way.
I would like to use a datatable or datalist or something to that sort.
Oh and I would like the visitor to be able to click on a name in the table and edit the data using the form controls not in the datalist or datatable itself.
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.

whats the exact use of static variables in overall programming in .net and for asp.net...
Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..
whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.
I have an ASP.NET application that needs to remember some info about a user (and what company they are from) across pages, within a session. I imagine this is a requirement of just about any ASP.NET application of a certain size. I've used a few different approaches over the years. In the past, I've passed around an id in querystring parameters like so: [URL] and then instantiated the object on each page (from the database). Another common way of doing it is storing my objects in session variables:
Session["User"] = currentUser; // store at login
User currentUser = (User)Session["User"]; // retrieve on some other page
which saves a trip to the DB, but I worry about memory used if the User object is complex and the site has many concurrent users. I have recently inherited an application that uses public properties on the master page, like this:
Master.theUser = currentUser; // store at login
User currentUser = Master.theUser; // retrieve on some other page
This saves the cast, and looks more readable to me I think, but I don't know if it's better or worse performance-wise. It also has some logic in the getter where if the private value is null, it tries to get it from the Session variable, though I'm not sure if that's never used (or used every get!?) or what. My latest idea is to use my page class. I have a custom page class derived from the standard System.Web.UI.Page base class. It includes objects like CurrentUser as public properties. This seems to work OK. I like it even better. But I really don't know what's going on under the covers. Can anyone give an opinion on which approach is better and why?
Update: I've done some checking use trace.axd and Trace.Write and it looks like neither the masterpage version nor the custom page class version "remember" the values between pages. The "get" methods have a line of code that checks if the User property is null, and if so, reads it from the session variable. This happens when a page accesses the property (Master.User or the derived class's this.User) for the first time on a given page, then subsequent requests can get the value (without going to the session variable). So thus far the best solution looks something like this:
public class MyPage : System.Web.UI.Page
{
private User user;
public User User
{
get
{
if (user == null)
{
user = (User)HttpContext.Current.Session["CurrentUser"]; //check if session[CurrentUser] is null here and log them out if so?
}
return user;
}
set
{
user = value;
HttpContext.Current.Session["CurrentUser"] = value;
}
}
}
Then on any webpage.aspx.cs, you can do something like this: UsernameTextBox.Text = User.FullName;
