State Management :: Serialize/Deserialize A Custom Class In And Out Of A Session

Mar 18, 2011

I'm trying to save a custom class in a session, but it just never gets saved, along with other sessions. Note that my SessionMode = STATESERVER, and i cannot change it to INPROC as per our business requirement. This is my class

public class User : ISerializable
private int _userId;
public int UserId
get { return _userId; }
set { _userId = value; }
//custom class
private TDB.tdbUser _tdbUserDetails;
public TDB.tdbUser tdbUserDetails
get { return _tdbUserDetails; }
set { _tdbUserDetails = value; }
//collection of custom class Sites
private List<Sites> _assignedSites;
public List<Sites> AssignedSites
get { return _assignedSites; }
set { _assignedSites = value; }
public User()
//Constructor code
protected User(SerializationInfo info, StreamingContext context)
this._userId = (int)info.GetValue("_userId", typeof(int));
this._assignedSites = (List<Sites>)info.GetValue("_assignedSites", typeof(List<Sites>));
this._tdbUserDetails = (TDB.tdbUser)info.GetValue("_tdbUserDetails", typeof(TDB.tdbUser));
[SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.SerializationFormatter)]
void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
info.AddValue("_userId", this._userId);
info.AddValue("_assignedSites", this._assignedSites);
info.AddValue("_tdbUserDetails", this._tdbUserDetails);

The calling code is just this: (User)HttpContext.Current.Session["TDBUSER"];

State Management :: Unable To Serialize The Session State In 'StateServer' And 'SQLServer' Mode

Dec 12, 2010

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",


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.

State Management :: Manage Custom Objects And Session State?

Oct 6, 2010

I've created a whole bunch of rather complex classes and now i'm starting to work on the user interface. Basically the user will open 1 page which will be used to load, edit, save an object. The object has many fields and they are often other classes i've created. To create a nice interface i've used popups and used AJAX to reload parts of the page to avoid reloading the whole thing.

My plan was to create the object and save it to the session. Then each time the page is loaded copy the object values to the asp fields and do the reverse when the page has been submitted copying the asp values to the object field then updating the session object.

So the code will go something like:


if session is not null load from session otherwise create new
this.txtID.text =
this.txtName.text =
etc etc

on submit: = this.txtID.text = this.txtName.text
etc etc
update session.

Is this what you guys would do? or am i over thinking this, seems like a lot of code to load all the object fields each time the page is opened and submitted etc.

Just looking to bounce ideas of off other developers :D

State Management :: Can't Retrieve Session Object From Class

Jun 30, 2010

my solution currently has a website project and a class library project. I am attempting to access a session object from my class library but it is always returning null. In a settings class in my class library I store these values like so:

private static SessionProperty<WebUser> _currentUser = new SessionProperty<WebUser>("CurrentUser", delegate { return new WebUser(); });
public static WebUser CurrentUser
get { return _currentUser.Value; }
set { _currentUser.Value = value; }

I can access this just fine from any aspx page codebehind like so:


However, if I attempt to do the same thing from a class in my classlibrary project it always returns null.

State Management :: What Triggers SessionStateModule Class To Start A New Session

Apr 20, 2010

SessionStateModule raises a Start event with a new seesion. Is there a pointer to "deep dive" information?

In particular,

(1) I want to preserve Session state information across a postback to external (web-based) services in my VS 2008 development environment, but am finding that my code is triggering the creation of a new session.

(2) I am using IIS to host WCF Service calls, and it appears that many of those calls trigger the creation of a session. I would like to dive deeper into this, and try to manage (reduce) the number of sessions that are created and their behavior.

Is this piece of code may be the main reason for serialization error ? I use the it nearly everywhere, so i can not simply detach and test it.

Unable To Serialize Session State - Server Errors

Oct 14, 2010

We have been receiving reports of the following server error periodically from users.
[OutOfMemoryException: Exception of type System.OutOfMemoryException was thrown.]
[HttpException (0x80004005): Unable to serialize the session state.]
Please note that non-serializable objects or MarshalByRef objects are not permitted when session state mode is "StateServer" or "SQLServer".

Once in a state where this error appears, it appears to be hit or miss whether the errors are reproducible locally. If they are, then we can usually reproduce them for a couple minutes, but not on every page hit. This usually tapers off on its own and usually has resolved itself by the time we get back in contact with the users. The Web Service has around 90-100 active connections during business hours. The only other site on this server is the staging version of this site, which gets hit very infrequently. The Session State is stored on the same SQLServer instance as the application database which is housed on a fairly large cluster of virtual machines.

Neither the Web Server or the SQLServer seemed to be taxed (either processor or memory-wise) while this is going on. The distribution of which pages are erroring seems to be comparable to the normal distribution for each page. There doesn't appear to be any pattern in terms of times of occurrence. We do have less errors on average on weekends (which correlates to normal site load), but even this appears to not be consistent. There also doesn't appear to be a correlation between the errors logged and any kind of logged performance monitor events. This includes an array of perfmon counters including:

.NET CLR Jit(w3wp)
otal # of IL Bytes Jitted
.NET CLR Jit(w3wp)IL Bytes Jitted / sec

The only pattern I can see in the logs doesn't correlate to the occurrence of these errors, but is the only pattern I can see. Looking at the perfmon logs we are seeing a pattern where the "Total # of IL Bytes Jitted", "IL Bytes Jitted / sec", "% Time in Jit", "# of Methods Jitted", and "# of IL Bytes Jitted" counters for the staging site (which shouldn't be getting any traffic) doesn't pull data for a 20-50 minute period after which there is an immediate spike in "IL Bytes Jitted / sec" and a jump in "% Time in Jit" for 2-20 minute of up to 99% for the main site.

State Management :: Session Mode State Server - Sending Asynchronous Request

Nov 5, 2010

Customer 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.

function SendRequest(msg, isBusy, chartMsg, vesselMsg)
_busy = isBusy;
if(chartMsg != null)
_element.SetMessage(true, chartMsg);
if(vesselMsg != null)
_element.ShowVesselLoading(true, vesselMsg);
_stuckWatchdog = setTimeout( "ClearPendingRequest();", 60000);
var message = msg;
var context = '';
alert( "Exception error on SendRequest(): " + e);

State Management :: Recreate State Session Database In SQL Server 2008?

Apr 5, 2010

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?

State Management :: Asp Create New Session State Cookie Each Time On Debugging?

Jan 21, 2011

I'm using the following line of code to display the number of users currently logged on:

lblNoOfUsers.Text = Membership.GetNumberOfUsersOnline().ToString()

I'm still debugging my application so it's on the local server. As I debug and stop then debug again, eventually lblNoOfUsers.text turns to "0" instead of "1", even as I'm navigating my application. It only turns to "1" again if I log out and sign back in. It's almost as though Membership.GetNumberOfUsersOnline my login are referencing two different session states. How is this possible? Does create a new session state cookie each time I start debugging?
