how can i check a session on my master page
View 4 RepliesI am working on some refactoring work from cold fusion to .Net and I have a login page which redirects to a mainpage --> aaa.aspx. It displays the current news from the database and then I have some links coming from the masterpage which are embedded inthe same page as well. This masterpage has links to pages which are in both .Net and CF.When the aaa.aspx was initially in Coldfusion, it would redirect to all these links in the masterpage without any issues, but from the time I re-wrote the aaa.cfm to aaa.aspx, the links in the master page that are embedded in the aaa.aspx would not work,i.e they would redirect back to the Login page. My session looks like it is persisting to the aaa.aspx page, but not to the master page elements.At this point, I am not sure as to what is causing this issue.
View 1 RepliesIn my application, session value automatically set into null.In certain workflow only it will set as null (Normally It's able to access value). Example, at the time of login, I will set session values. While, user deleting some entries from drop down list of specifc page,client script will show message like selected entry deleted. After that, flow point will move to master page. There I have to access session variables. It's getting null value. I tried to debug with Quick watch, at the pageload of master page only value set into null (automatically).
View 6 RepliesI have a masterpage that calls all kind of external files from the server on startup, mainly css and jquery files. So, problem is, every time I open the page, there are a lot of roundtrips to the server to request these files.After the initial loading has been done, everything is ok.
Will it be possible to cache these small files to the client side, with a predetermined expiration date, so when i next open the page, I will keep the roundtrips to the servers at a minimum?
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 RepliesMy prior asp.net apps used windows authentication on an intranet. Now I'm developing an app for the internet and am stumbling over how to properly manage user sessions and state.
I first developed my web site functionality; created the SQL DB and got all of the pages to properly handle the data. Then, I installed the SQL Membership database and was able to get the CreateUser, Login, Logout pages to work. On the Verify process for the Userid, I added a step that will take the membership UserId value and create a Company record in my tables and link my CompanyId key with the UserId.
At Login time, I create a CompanyId session variable; each page uses it to retrieve records for the user. When Session Timeout occurs and the user click a link to another page, the app redirects properly to a Login page. However, if the time expires and then the user interacts on that same page, 'Object not set to an instance of the object' - the CompanyId session variable has expired.
What is the proper way to handle this? I'd like the page to automatically redirect to a TimedOut page (this would happen automatically without the user doing anything).
I considered writing a Function where I pass the Session variable I want and the Function sees if it exists; if it doesn't it would do a Response.Redirect to the TimedOut page...I can't get the Redirect to work in a Class Function ('reference to a non-shared member...').
I assumed that I should set CompanyId as a Session Variable so each page knows the user to get data for. Another approach is to use the membership User and if it is still valid, do a DB lookup to get the CompanyId. I did not choose this because I felt that it would increase DB traffic and web traffic.
Here are several relevant settings from my web.config:
<sessionState cookieless="UseDeviceProfile" />
<authentication mode="Forms">
<forms loginUrl="~/UserTasks/Login.aspx" />
It feels like there should be a straightforward answer to this but I am missing it.
I have one web application. In that, I have two pages. One is view/edit page and another one is login page. The view/edit page contains one edit button and one login button.
First I execute view/edit page, at that time I dont want to show edit button. When user clicks login button, the page will be redirected to login page, where the user has to enter username and password. If user enters both correct, again the page will be redirected back to view/edit page. This time, the edit button has to be shown to make some modifications, since the user is authenticated.
I tried this thing by using session with cookieless. It works perfectly but some times it shows web page not available. I made session timeout 120 minutes and cookieless is true. In URL session ID also available.
So, whats the alternate way to maintain user log state or whats wrong in web.config file.
I am a little bit new at handling multiple sessions congruently.
Basically i have created a chat application. In which i have a moderator page.
Now the moderator has the privilege to block particular users from the chat. Every user including the moderator has a session variable defined as Session["UserID"].
e.g for the username "moderator" the Session["UserID"]=moderator.
Now as i am logged in as the moderator how do i delete the session of a particular user whom i want to block the chat from commencing.
I'm working in vb language and I would like to know how to store the values of asp.net controls (textboxes, selected items of combo boxes etc) so that I will be able to display them on a different page. I was using cookies but it's not working.
Page 1
Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Response.Cookies("FirstName").Value = txtFirstName.Text.ToString()
Response.cookies("Date").value = cboDate.selectedItem.Text.ToString()
Response.Cookies("FirstName").Expires = DateTime.Now.AddDays(1)
Response.Cookies("Date").Expires = DateTime.Now.AddDays(1)
End Sub

High level description is this: I have a value that is pulled from a session variable. In the PageLoad method, the value is stored in a local variable. A literal control is set on the page with that local variable and then the value is stored in the database. There is no default value for the literal control on the aspx page. For some reason, the literal is displaying an incorrect value, but the value placed in the database (using the same local variable) is correct.

I have a very basic application with user authentication. I also have a grid in my masterpage that shows all the users logged on. However, after a user logs out, it still shows them to be logged on in the users grid for the duration of the session, which is 20 mins. How do I get the grid to exclude users who've logged out? Here's the code behind for the grid:

I am looking for an elegant (i guess as elegant as it can be) solution to caching a users profile on login (whether it is session, cache, cookie, etc) and keeping it in sync when a users profile is changed. How do you guys handle this? Just simply call a Flush() method in your Save() method that invalidates the cache?

In my ASP.NET application I need to allow only one session for a user ? When a user does login more than once, I want to get to user's previous session and abandon it. I'm keeping track of all user sessions by means of session id. But Session.Abandon is available only for the current session associated with a request and not previous sessions. I have the session id of the user's previous session but how can I end it ?

View 3 RepliesI am trying to create a system in which there will be a single user accessing his acount from two endpoints simultanously.
I think this is possible.
1) How to restrict the user to have only one session at a time?
2) How to change it to have limited number of sessions per user at a time?
In this code Page.User.Identity.Name is null

I thought the Name always was set when user was Authenticated?
If this is not the case, how should I do instead?
We have take over a classic asp site. Everything works fine, but we are making improvements to some reports and adding new reports, so we are doing this in .NET, with that said, after reviewing the secuirty code, there are 2 sessions that are set and used thru-out the site as part of some of the individual page queries.
I know that the sessions are being populated, because the reports that use those values return records.. now with a new report we are working on, i need to pass those values into my query. But when i try using the session names the page is coming up saying the following:Object reference not set to an instance of an object.
Is there anyway to add something to my page code to see what sessions are actually being created and their values.. maybe im using the wrong variable names.. but the security code is pretty straight forward.. at login, if successful, 2 values are returned and stored in 2 sessions.. i need to use those with my new page.. so trying to figure out why the existing pages work fine with that and my new page does not..
Basically, i'd like to write to the screen the session variables that are being created on the login page.
I have a aspx page and there is a web user control that must load dynamically with the data related to the aspx page....
