I am currently working on asp.net 3.5 with C#. In our application Link buttons are used in Grid to redirect page. means when user click on link from Home Page it will redirect to Job details and when user click on Job details link grid it will redirect to VehicleDetail page. My problem is how to store value on jobDetails page from which page user came. without using Session , Static variable when page is redirect.

View 9 RepliesIs it safe to access asp.net session variables through static properties of a static object?Here is what I mean:
public static class SessionHelper

public static int Age

Is it possible that userA could access userB's session data this way?
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.
Is there room for issue in the following code in terms of multiple users of the same web application? I mean, I know that a purely static string will be shared across all sessions for a single ASP.NET application, but since this explicitly refers to the Current.Session, even though it is static it seems like it would always refer to the session instance of the "current user." But an error is happening that could be explained by everyone sharing the current value of Mode and thus the most recent change overwriting everyone else's mode value. (As a background: This string is in a Helpers class that is used throughout the application. I do not want to make references to Session["Mode"] throughout the application and do not want to have to pass Session["Mode"] in every method call from an aspx.cs page.)
public static string Mode
{
get
{
var value = HttpContext.Current.Session["Mode"];
return (value ?? string.Empty).ToString();
}
set
{
HttpContext.Current.Session["Mode"] = value;
}
}
I write a simple static method in my web page. How can i access session["id"] into method? I dont have access.For example:
public static void myFunc()
{
Session["id"]= 100;
}
I have a class called EditMapUtilities. Here are some class properties that I want to persist:
public class EditMapUtlities
{
public static Boolean isInitialEditMapPageLoad
{
get { return SessionHandler.isInitialEditMapPageLoad; }
set { SessionHandler.isInitialEditMapPageLoad = value; }
}
// REST OF CLASS NOT GERMAIN TO DISCUSSION AND OMITTED
}
Here is my SessionHandler Class following the pattern from this post Static Session Class and Multiple Users:
using System.Web.SessionState;
public static class SessionHandler
{
private static HttpSessionState currentSession
{
get
{
if (HttpContext.Current.Session == null)
throw new Exception("Session is not available in the current context.");
else
return HttpContext.Current.Session;
}
}
//A boolean type session variable
private static string _isInitialEditMapPageLoad = "EditMapInitialPageLoad";
public static bool isInitialEditMapPageLoad
{
get
{
if (currentSession[_isInitialEditMapPageLoad] == null)
return true;
else
return (Boolean)currentSession[_isInitialEditMapPageLoad];
}
set
{
currentSession[_isInitialEditMapPageLoad] = value;
}
}
}
I am still learning OOAD. I want to keep relevant properties with relevant classes. I also want to keep all Session stored variables in one place for ease of maintenance and to encapsulate the session keys and calls. I feel like my design is too coupled though. How can I make it more loosely coupled? Is my editMapUtilities class too tightly coupled to the SessionHandler class? How would you do it better?
i have two text boxes and one button in web form. I need to display the contents of text boxes in a datatable in the same form, when i click on the button.
How can i do this using session array. I need to store values in session array. and get back the values from session when i need .

View 1 RepliesI am creating a static variable and adding to session.This variable has value that is user specific. Now I am getting a problem with this users are complaining that they are getting values that should be another users. It's like a mix up with session. Could this be because of static variable declaration?
View 2 RepliesI have an asp.net application with c# language. I have a common class which maintain the constants and static variables and fields. I also have a login page. If the user logs in successful I set IsLoggedInSuccessfull as a static boolean variable in common class.
My question is: Will this only work for a specific user session or for overall application ?
Edited:
Based on some answers I got another question here.
let say i am using the Static method as Authenticate(User objUser). intention is to call this method when user clicked log in button. where on login button I am let say prepare the User object with certain parameters required for login, then passing to this method. what would be the impact there? let say I have single server for now (no server farm or garden). then there will be the single application level method to authenticate the user, right? and say 10000 user are going to logging in to this site/application then how authenticate() method comes in behaves ? will CLR automatically manage threading there ?
Currently in an .aspx file, I am storing a value (filename that was created in that session) in an hidden text box. When the user clicks on the "Print" labeled Hyperlink control, it opens the file that was stored in the hidden text box control. But when the user goes to different screen (in the same session), I loose the filename value that is stored in the hidden text box control. So I would like to store the filename variable in a session variable. So that if the user leaves this .aspx file and comes back to this .aspx file I can load the value into the hidden text box from the session variable.
View 11 RepliesWhen 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.

I'm trying to get asp.net to store viewstate in the session rather than bulking up the html.
Now i've read that asp.net comes with the SessionPageStatePersister which can be used instead of the default HiddenFieldPageStatePersister to do this. I was wondering how i go about dropping it in?
This is what i've got so far:
I think i need to create a PageAdapter that returns a SessionPageStatePersister from its GetStatePersister method, and somehow get the page to use this pageadapter. But Page.PageAdapter only has a getter, so i'm not sure how you set it.

I'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?
consider this scenario: a user on my website has a profileID. There are some pluginID's associated with this profileID.
E.g.: User1 might have 2, 3 and 5 plugins associated with his profile.
When the user logs in, I store the profileID of the user in a session variable cod. ON a certain page, the user tries to edit the plugins associated with his profile. So, on that page, I have to retrieve those pluginID's from the DB.
I have applied this code but this fetches only the maximum pluginID from the DB and not all the pluginID's.

I was trying to figure out how can I store multiple pluginID's in this session variable?
