I'm building a site (it's amazing how much you can do and still not know what you're doing).I have my visitor login from a login.aspx page and, when authenticated are redirected to a Portal page. On that Portal page at pageload I set a Session variable "UserName" using the User.Identity.Name like this:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If User.Identity.Name <> "" And User.Identity.IsAuthenticated = True Then
If Page.IsPostBack = False Then
Session("UserName") = User.Identity.Name
End If

I cannot get a formview populated using a session variable value from a previous page.
<asp:FormView ID="FormView1" runat="server" DataKeyNames="RegId"
DataSourceID="SqlDataSource1" DefaultMode="Edit"

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 have a website live in asp.net
now if user closes browser. the session does not get killed.
I spoke with friend and he said that cannot be done as sessions are on server.
but i see banking website who kills session when browser is closed.
Is it possible to assign the connection string in session variable and is it the good way to declare in session.
provide the sytax for accessing connection string from session variable
Example scenario:
User login has a list of associated 'accounts' it has access to... this list of accounts is stored in a database table, say tblAccountAccessControl, something like:
login, accountID
userA, account123
userA, account456
userA, account798
userB, accountABC
userB, accountDEF
etc..
This info is used throughout the web application and determines the 'domain' of information the particular login has access to. For example there are many other tables that have the 'accountID' field and whenever a page pulls data from the table it only pulls data that the currently logged in user should be allowed to see, based on that tblAccountAccessControl data.
The security question:
Do I need to query the database every time I need to get this list of allowed accountID's? I was about to use a plain old query string to pass a particular accountID to another page but quickly caught myself as I realized that would be a major security flaw (the receiving page was going to use that accountID to grab info from the database, and there would be nothing preventing a user from simply typing in a url manually to get data from an accountID they are not supposed to be allowed to view). So I then thought I'll just store the list of accountID's in a session state variable so they will be carried with the user throughout the session.
But then I remembered there are tools out there that allow you to easily intercept and modify asp.net viewstate information and I'm not sure if that would included session state variables, but I'm guessing they would. Is there a way to create a secure query string? If I used session state would that session state information be exposed and modifyable by utilities out there? Am I just stuck having to query the database every time I need this info to assure security? What about encrypting it and then storing in session state variable (just thought of that one)?
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 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 have this code that loop through table controls how do stick the seleted information into a session variable. Then i have to pass it into another page table control.example code

I would like to know if the way i'm dealing with session variables is the right way, and also how to fix this error i'm getting:
FormatException: Input string was not in a correct format.
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 ?

How do I abandon the session when the user closes the browser window instead of pressing the logout button in ASP.Net 3.5 application.
View 5 RepliesI 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.

i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource();
sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString();
sq.SelectCommandType = SqlDataSourceCommandType.Text;
sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1";
string result = sq.Select(some overload that's stopping me);

View 4 RepliesI am working on a site in which some pages are to be run on secured server(ie https) & some on non-secured(ie http) eg Login, User Information, etc. will be run under https & View cart, etc. are to be run on http. Now, when user chooses some products in his cart, he is prompted to enter login details. After he fills in his login detail(ie in https), he is redirected to Checkout. But here the Session doesn't picks the value and it shows Session[UserID] value null. So, rather then redirecting to Checkout it shows MyAccount page. Does anyone know how to pass Session Value from https to http.

View 4 RepliesCustomer were getting "View State Validation Error" due to worker process recycling at our production webserver and to fix that i applied machinekey and then move my Session state Mode from In Proc to State Server to retain session data and not kick out the customer to relogin. I had serialization issue with one object which has to be stored in session but when i moved it out of session i could able to resolve the issue.
But doing all these i was partly successfull in keeping the user in their session when Worker Process recycle event occurs.I was able to refresh the page or make a post back by clicking the refresh button and also able to retain the session values. But the Problem occurs when sending asynchronous request to server which we do periodically every 15 minutes from the moment the user logs in.The web page doesnot update data on website when sending asynchronous request.By Debugging I found at this particular code point it fails to make a postback which is required.
<%=GetHintFromServer%> (When there is no Worker Process recycle i t gets replaced by
WebForm_DoCallback('__Page',message,ShowHint,null,null,false) on postback) Everything works fine when there is no Worker Process Recyling but when it happens looks like sending request asynchronously using javascript fails .Remember When I make a post back by manually clicking submit button everything works fine.
SendRequest(Asynchronous)
function SendRequest(msg, isBusy, chartMsg, vesselMsg)
{
try
{
//confirm("msg"+msg+"isBusy"+isBusy+"chartMsg"+chartMsg+"VesselMsg"+vesselMsg);
_busy = isBusy;
if(chartMsg != null)

//confirm("chartMsg"+chartMsg);
_element.SetMessage(true, chartMsg);

I am new to .net 4.0 and am using EF Model and SessionState Mode=SqlServer and I am getting this error below:
Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.
I checked the stack trace and its complaining about
[assembly: global::System.Data.Objects.DataClasses.EdmSchemaAttribute()]
[assembly: global::System.Data.Objects.DataClasses.EdmRelationshipAttribute("PoplarGroveModel", "tblMenuRole", "tblMenu", global::System.Data.Metadata.Edm.RelationshipMultiplicity.Many, typeof(PoplarGroveDataModel.Menu), "tblRole",
[Code].....
I marked it as serializable but then it complains about System.Data.Objects.ObjectContext is not marked as serializable and hence throws the same error.
Our ASP.NET App uses ASP State Session Management and has been rebuilt about 2 years ago [With .NET Framework 2.0]. We are currently in .NET framework 3.5 and have moved to SQL Server 2008 - but continue to use the same ASPState database. The State database has been upgraded to SQL Server 2008. Since then we have are seeing timouts/locks on ASPStateTempSessions table. I am wondering if we have to rebuild this database from scratch with some newer scripts?
