Session - Saving Variables In Page?

Dec 25, 2010

I'm trying to convert a game I made (WindowsFormApplication) to an ASP.NET page.

My Problem is that I have a lot "private" variables in my WindowFormApplication and those variables are important for the game. But when after I Declare all my variables (in my Page_Load), they turn null no matter what I do(click a button, refresh the page).

Is there anyway to save my variables between buttons (other than Session, because I'd have to create like 6 more sessions)

Web Forms :: Session Variables Value Lost On Page Refresh?

Jul 27, 2010

I am developing an application using Visual Studio 2010 and SQLServer 2008. My application has two pages and the first page contains a GridView with all the records "User Administration" and when user click on any Username (template field ->linkbutton) I read the USERID like this.

Session["UserID"] = e.commandArgument;
Response.Redirect("UserOperations.aspx");

which takes it to the Data Entry page where user updates the information and save the data.

The problem i am facing is that when I hit the browser REFRESH button couple of times the session variables looses the value which is trouble for me as I am using Session Variables for different purposes.

Web Forms :: Post Data To External Page And Set Session Variables

Aug 17, 2010

I have an app which has a form that used to use AutoPostBack rigged controls (dropdowns, radiobuttons etc.) in an updatepanel, and I used to set session values on each postback. I posted the form using PostBackUrl to an external page, using a bit of javascript OnClientClick to copy my data into meaningfully named hidden fields.

Now, I've had to rewrite the AutoPostBack-ing controls so that all the cascading dropdown work and date calculation etc. is done in JavaScript, and not in C# - no more postbacks, no more updatepanel.

This means I've lost the ability to set my session values on postback. Can anyone think of a solution for setting these before I post my form? I need to set the session variables, plus post (querystrings are not an option) to the external page with the values from my form - and actually send the user to the external page, too.

Adding / Removing Session Variables On Page OnInit/OnLoad In C#?

Jan 16, 2011

I am using C#.

I am having below code in C#:

protected override void OnInit(EventArgs e)
{
try
{
if (Session["boolSignOn"].ToString() == "true".ToString())
{
lblPanelOpen.Text = Session["panelOpen"].ToString();
}
else
{
lblPanelOpen.Text = Session["panelOpen"].ToString();
}
}
catch (Exception ex)
{
Logger.Error("Error processing request:" + ex.Message);
}
}
protected override void OnLoad(EventArgs e)
{
try
{
if (!string.IsNullOrEmpty(Session["panelOpen"].ToString()))
{
lblPanelOpen.Text = string.Empty;
Session.Remove("panelOpen");
}
}
catch (Exception ex)
{
Logger.Error("Unable to remove the session variable:" + ex.Message);
}
}

In above code I am having a Session["panelOpen"] variable which is created from another user control and once my page is trying to render, I am storing Session["panelOpen"] in my hidden lblPanelOpen.Text on page OnInit() method, however when page is loaded completely then I am trying to remove the session variable.

State Management :: Session Variables Destroyed With Each Page Load?

Apr 22, 2010

I'm using the beta version of Visual Studio 2010. I'm running my ASP.NET 4.0 website through the debugger. Whenever there is a page load (e.g. clicking on a link, a postback) the session is ended and a new session is created. This wipes out all the session variables and makes debugging impossible. How to get session variables to persist across page loads?

Is this problem unique to running ASP.NET in a test environment or unique to the beta 2 version of VS 2010?

I am aware that I cannot use the same url when I define the url in the web.sitemap file.

State Management :: Set Session Variables In One Page And Retrieve Them In Code File?

May 12, 2010

I'm trying to set session variables in one page, and retrieve them in my code file in the page that it posts to.

I keep getting this error. I put the correct namespaces in, and enabledSessionState = true to my application files, but no luck.

Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.

I'm just calling a session variable, and I get that error

e.g,

Public AUID As Integer = Convert.ToInt16(Session("AUID"))

.net - Session Variables Clearing On Response.redirect ('page.aspx",false)

Mar 1, 2010

I have an webforms app that loses it's session variables on response.redirect. I've read Bertrand Le Roy's blog about this and still can't get it to work. The page works in production. However, when I try in the VS2k8 IDE, the session variables are there right before response.redirect and on the first line of the next page, the variables are nothing. I've confirmed the session id is the same so I'm not skipping sessions. The target page is relative so the web server doesn't think we're changing sites (as confirmed by the sessionid).

Response.Redirect("menu.aspx", False)

IIS InProc Session Variables Randomly Not Written To Session

Nov 12, 2010

There are reams of info out there about things causing InProc session to drop session objects, but that's not what's happening here. We're missing individual variables within stable InProc session objects, and are not sure whether they're not being written or being lost after a successful write. I've confirmed with WinDBG that the sessions are live and contain some, but not all, of the data written to them.

Guid g = System.Guid.NewGuid();
this.Context.Session.Add(g.ToString(), result.ImageData);
output.Write("<img src="display.aspx?id=" + g.ToString() + "">");

This code is pretty straightforward, and it works flawlessly in Test. In Production, under heavy load, though, it fails ~1% of the time. If Mr Smith visits the site and attempts to display 4 pieces of image data, 2 of them might be saved in his session and two of them be lost. The InProc session object for Mr. Smith exists. The traffic logs show he clicked 4 times, each with a different id param. But there are only 2 guids in his InProc session object, instead of 4. The 2 session objects we did capture do correspond to 2 of the id's shown in the traffic log (his 1st and 3rd clicks.) The traffic logs for his 2nd and 4th clicks, though, show a guid id that's not in his InProc session object.

Lines 1&3 of the above code obviously worked for those 2nd and 4th clicks, or he'd not have had the id in the URI for him to click. Line 2, however seems to have failed silently in some way. If any exception had been thrown, I'd expect we'd not ever have arrived at line 3. I can't see any way for the user to receive the guid id, but the session to fail to have it. The other possibility is line 2 worked successfully, but the variable later disappeared, how I cannot even imagine.

Details:
ASP.NET v3.5
IIS 6
No Web Gardening

We're running a web farm, but users constantly return to the same server. I'm researching now whether there's any way users might be slipping off to the other server.

I want to password protect an area of a website by a login/registration form.

I'm using session variables to check wheter the user is logged in or not. I already have a database with users/passwords... so I thought that the membership approach wasn't an option... (correct me if I'm wrong)

in the constructor of the controller of the area I want to protect I've added the following:

In my .NET web app, I keep basic user info in a user session object. I also usually keep a director class in the session; which is basically just has info about whatever thing it being worked on on that screen (like a customer id).

I am trying to keep from adding a ton of sessions. I also want to make sure at any given time ONLY the sessions that are necessary are in memory.

VS 2008 - Using Session Variables Get Corrupted

Jun 10, 2010

I have a situation where my session variables seem to get corrupted. I Page_Load I am calling 2 subs. Each of them fills a GridView with data from a table. I am saving the content of each Data.DataTable into Session Variables:

Get_Summary_Last_Completed_Shift()
code in sub:
mySqlDataAdapter.Fill(mySqlDataTable)
Session("mySqlDataTable1") = mySqlDataTable
GridView1.DataSource = mySqlDataTable
GridView1.DataBind()

Code:
Get_Petroleum_Disbursement()
code in sub:
mySqlDataAdapter.Fill(mySqlDataTable)
Session("mySqlDataTable5") = mySqlDataTable
GridView5.DataSource = mySqlDataTable
GridView5.DataBind()

After I call the 1st sub and I debug the session variable "mySqlDataTable1" contains all the data from the table. After I call the 2nd sub and I debug the session variable "mySqlDataTable1" has been changed and contains a mix of data from the 2 tables.

Implementing Security With Session Variables?

May 5, 2010

I am doing web based projects in dotnet. Currently I am implementing security using session variables. I keep current user id and user type in session and authenticate user from these session variables (say Session["UserId"],Session["UserName"] and Session["UserType"]).

I've heard that such security can be broken and applications can be hacked very easily, like it is possible to get session id and directly connect to that session id etc.

Session Variables Inside Of SharePoint?

Oct 26, 2010

I am having with asp.net app inside of SharePoint (as page viewer).

When the Default page is loaded, it works fine. However, when I try to go to next page, i am getting a null reference exception. It looks like my session variables are becoming null on the next page (even though I set them on the previous page). Here are a couple things that I tried to diagnose the problem.

I try on the couple other computers; some work fine, some still don'ts. In the property of the page viewer inside of the SharePoint, after I click on the "Test link", it started to work fine until the session expired (on the computer didn't work initially).

I am not sure if there are settings that I need to check on the browser or the app server.

Loading Cycle And Session Variables?

Jan 26, 2010

I am setting a session variable when the user selects a value from a dropdownlist (SelectedIndexChanged) in webusercontrol #1.

The page then refreshes and I thought that webusercontrol #2 on the page should be able to access the session variable in its page load.

However the session variable is not available until the user refreshes the page again. I'm assuming that the page is refreshed before the session variable is updated.
