View 6 RepliesState Management :: Session State Returning Null Values?
Apr 29, 2010I 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 State Blank (not Null) After Deployment?
Nov 8, 2010On 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.

Feb 17, 2010I 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 Became Null - Maintain Data?
Aug 17, 2010I 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, 2011I 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, 2010I 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?
View 3 RepliesState Management :: Session Parameters Are Null In An IFrame
Jan 30, 2011I 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.

Dec 16, 2010In my application, session value automatically set into null.In certain workflow only it will set as null (Normally It's able to access value).

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).

This works ...

else

This does not work?

State Management :: What Triggers SessionStateModule Class To Start A New Session
Apr 20, 2010SessionStateModule 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.
