State Management :: Session State Blank (not Null) After Deployment?

Nov 8, 2010

On my development machine, the session state data is retained after a post back to the server. (XP VS 2008) (This is true if running from within VS or if running in browser with localhost.)On the deployed test server, the session state is blank in IE, but works in Firefox. (Svr 2003 IIS 6)Both machines are running the exact same code with the exact same imputs and same web.config. There is no code between the post backs that write to the session state.Newest addition to the server would be the consumption of a WCF web service. Could this be a symptom of something missing on the server(s) when trying to connect with WCF? I could not find any information other than installing the 3.0 framework. I have 3.5 SP1 installed on the test server.

State Management :: Null Session In IE But Not FF After Deployment

Feb 17, 2010

I have an app that worked perfectly in development (Visual Studio 2008 Dev Server/Vista), was setup to use cookieless sessions in the web.config, which worked fine. Now rolled out into production (win2003/IIS6) configured as a Virtual Directory. But I'm having Null session issues after a button click. The problem doesnt persist in FF but in IE8. I tried to change session state to cookies and cookieless (InProc) with no go.

State Management :: Session State Returning Null Values?

Apr 29, 2010

I have a clear button and a textbox in an aspx page. I set the session variable in this page as

String str = Textbox1.Text;

Session["TypeIds"] = str;

and I clear the sessions in a clear button event as

Session["TypeIds"]=null;.

Then when the user types some value in the textbox ,on Response.Redirect on another aspx page, the session variable returns null values.It does not retain its session state. The session state has to be maintained in the next page. Is it because this clear button event and setting explicitly to null creates this problem?

State Management :: Session Does Not Persist After Postback On Deployment

Nov 22, 2010

I ve been searching for this on various forums and came through a number of supposed solutions which didnt work for me.

My web form works perfectly for me when on development and after publishing on IIS but when I try to access remotely the session value is always null.

I do these things in the following order and when accessing remotely I always get the exception i throw when session is null.

I debugged it and my list is never null when reaching the assignment point.

[code]....

in webconfig I have the following tag which I saw as an answer in many forums

<sessionState mode="InProc" cookieless="true" timeout="200" />

State Management :: Session Became Null - Maintain Data?

Aug 17, 2010

I have a requirement where i need to download mutiple files as a single zip file.There is linkbutton named HOME as well in the page. when this linkbutton is clicked it should redirect to homepage.aspx. I found a ICSharpCode.SharpZipLib.dll in net and used in my website. Here is the code

[Code]....

With the above code i got the expected result i,e. i can zip the files and save on client system. But the problem is after saving/canceling the zip file if user clicks on linkbutton in the page_load event Session[getdata] became null. there is no data in Session. what might be the problem? Actually it should redirect to homepage.aspx but its going to login.aspx because Session[getdata] is null.

State Management :: Session Key Gets Null While Object Alive

Jan 27, 2011

I have a Authorizeclient.aspx.cs page where I set my session value.Authorizeclient.aspx is a blank page. HttpContext.Current.Session["nodeID"]="0". This session value changes from 0 or non zero which depends on the value returned by Database. If no value is returned I assign HttpContext.Current.Session["nodeID"]="0" as the default state else I assign HttpContext.Current.Session["nodeID"]=resolve(nodeID).ToString()

Till this part it works fine as expected. However, I have a requirement that I need to read the nodeID from Session in other application on the same server. I mean this application too is part of the root project where I initially created the Session and set it. The strange thing is the Session["nodeID"] in application gets null "SOMETIMES" Not always. I am trying to read the Session in Page_Load. Sometimes it works fine and sometimes it gets null. Moreover the session object do not die and I can see other keys like Session["Themes"] etc there. The session is in InProc mode and have 20 minutes timeout time.

State Management :: Session Suddenly Become Null - Need To Rebuild

Jul 28, 2010

I have a strange problem with the session. I have global.asax with code in the session_start event. This code calls some code that I have in a helper class. When I first run the project in debug everything is fine. However when I stop debugging and then re-run the project it fails and I have discovered that once the code in the helper class is hit the session is null. If I look in the global.asax session_start code the session is instantiated before it enters the helper class. If I then re-build the project and the re-run it everything works fine again! Why does the session suddenly become null and why does a re-build fix the problem?

State Management :: Session Parameters Are Null In An IFrame

Jan 30, 2011

I have a "one page application" (ASP.NET 3.5, VS 2008, IE7) that uses Default.aspx as it's page, and holds an iFrame within "floating panel" (asp:Panel with extenders).

As the desired behavior is to allow users to reopen the application by refreshing the page,

I added this to the Default.aspx.cs:
protected override void OnPreInit(EventArgs e)
{
if (!IsCallback && !IsPostBack)
{
Session.RemoveAll();
GeoApplication.DAL pDAL = new GeoApplication.DAL();
Session["DALinstance"] = pDAL;
}
}

However, when the iFrame page lifecycle starts, the Session["DALinstance"] parameter is null. I've tried to put some additional parameters and those were null as well.

State Management :: Session Values Automatically Set Into Null In Masterpage

Dec 16, 2010

In 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).

State Management :: Session Null Empty / Sending Error

Mar 30, 2010

Can anyone explain to me why this first example works fine but the second, which would use a little less code and in my mind appears to achieve the same result, yet throws a null ref error?

This works ...

if (Session["sid"] == null || Session["sid"].ToString() == "")
{
// session is NOT valid.
}
else
{
// session is valid.
}

This does not work?

if (String.IsNullOrEmpty(Session["sid"].ToString()))
{
// session is NOT valid.
}
else
{
// session is valid.

State Management :: Application State And Session State?

Oct 2, 2010

User Interface: 2 Labels; 1 Buttons

Requirements: Create a Web Page in ASPx that will do the following:

1)One label will provide a count of how many times Button 1 has been clicked in the current session.

2)One label will provide a count of how many times Button 1 has been clicked by all users of the application. The Application Code for the Button should start at 100 (set this in the Global.asax file). this is what i have so far but i cant seem to get the application state to work properly.

aspx.vb

Partial Class _Default
Inherits System.Web.UI.Page
Dim clickcount As Integer

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Session("ClickCount") Is Nothing Then
clickcount = 0
Else
clickcount = CInt(Session("ClickCount"))
End If
If Not IsPostBack Then
If Request.Cookies("UserName") IsNot Nothing Then
Label1.Text = "Welcome Back " & Request.Cookies("UserName").Value & "."
End If
End If
Dim clickCounta As Integer = CInt(Application("ClickCount"))
End Sub

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.

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);
}
if(vesselMsg != null)
{
confirm("chartMsg"+vesselMsg);
_element.ShowVesselLoading(true, vesselMsg);
}
_stuckWatchdog = setTimeout( "ClearPendingRequest();", 60000);
var message = msg;
var context = '';
<%=GetHintFromServer%>
}
catch(e)
{
alert( "Exception error on SendRequest(): " + e);
}

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",

[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.

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?
