State Management :: Clearing Session Data From Modeless Popup Window?
Sep 22, 2010
I am using Post method to generate crystal reports. The user requirement is to show the report in a modeless pop up screen.
The session data needs to be cleared as it may at times contain a very large dataset.
One implementation I have placed in at present is - placing a button "Close Button". When user clicks close button, I am able to clean up the session content as well as close the window.
The issue I am facing is to get the handle of the modeless window when it is closed using the x button. Also, since the pop up window is modeless, the user might have moved to another screen, henceforth the parent of the popup window is already changed or out of context.
How do we clear the sesssion content when the issue condition arises?

Existing applications works fine with IE 6 and 7, the problem occurs only with IE 8. A new session is created everytime a window.open is used to open a new asp page. This does not happen in IE 6 or 7.

We have a scenario where we need to store large tables of data on Session in asp.net page. on a highlevel we have to store following data
1> A table (table 1) with 1000 rows and 8 to 10 columns.
2> A table(table 2) with 500 rows and 8 to 10 columns (actually user can add the data from table 1 to table 2, so as user keeps on adding from table 1 we remove the data and put it in table 2)
3> Another table(table 3) with 1000-1200 rows each having 3 columns.
We are having a webfarm, so we need to store it in either SateServer of Oracle DB,What would be the performance implications of storing such huge data on the server.
One more thing is at any point of time max of 70 -80 people will be accessing our website, so will this cause any performance degradation?

I want to be able to persist data across a session but do this outside of the built-in session state object. Why is a long story that I will not go into here. I just need to know where I can put data other than in the session object that will persist across the specific session.

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.

This is weird. In my newly developed chat application, when I invoke Response.Redirect, I am losing my session data. What is particualrly odd is that this sometimes seems to occur after a slight delay, so I reach the page, and then the session info gets lost momentarily thereafter. Mostly though it seems to get lost immediately. I have of course googled this issue, but yet to find anything that speaks to my problem. SessionState is in InProc mode. Session state has been working fine for me until this unexpected problem, so everything is configured right. So far the only workaround I can think of is to use a link instead of a button, and use javascript to call a server-side function on onclick to do the work I need to do before the link gets invoked. Messy, and I'd rather not go that way unless there's no alternative.
Just to preempt one red herring, I do use Response.Redirect(<address>, false).
The problem occurs both on the testing and production servers. I'm running ASP.NET 3.5 on IIS7.

I am creating a web application that will be running on an infrastructure which will utilise a number of web servers, web gardens and a load balancer.
As the application is using Sessions, and that our application is using Oracle as the database, we would like to use the database to save the Session data. However, I am struggling to find any good examples on how to do this with Oracle.
I note that Oracle provides the following class: Oracle.Web.SessionState.OracleSessionStateStore, but I am unsure what I need to do in the Code Behind and what if any tables do I need to create in the database.

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);
}
}

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?

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 asp.net create a new session state cookie each time I start debugging?

I am trying to set a session variable in the global.asax file and keep running into the problem that the Session is null.
I am running my application in VS2008 and using asp.net 3.51.
Here is my code:
1. In my web.config file I have enabled the session state and added the following line;
<sessionState
cookieless="false"
mode="InProc"
timeout="60"
></sessionState>
2. In the Session_Start procedure in the Global.asax file I set the session variable to a default value.
[Code]....
My problem seems to be that when the Application_Error procedure is executed the session state is lost.
Does anyone know why the session state isn't available in the Global.asax file.

All we have a global ships position tracking website which runs smoothly until IIS application pool recycles.When there is workerprocess recycling looks like session state expires as a result i loose all session data and when customer clicks refresh button he is redirected to login page.
In web.config Session state mode is set to InProc so i changed it to State Server but to my luck i have MAP object which is not serialiazable which is causing the maps from not appearing on the website.I tried adding serializable attribute to the object class but still not succesfull.Our website is accessed by our customers whose count is more than 1000.
Changing the session state mode from InProc to StateServer can really slow down the response time so
Is it good to go further fix the serailizable issues and move to state server?.
Is there any way I can retain my session data when application pool recyles?..
Stopping Application pool from recycling may not be a good idea considering health factor of web server.

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?

I am building a web app that is limited to one database, therefore I cannot use the ASP.NET config tool. As a quick means of getting this app online, I tried to use a simple session variable. The login page verifies the user's credentials, and if they pass, it sets the session variable to a certain value. All other pages check in the page_load event whether or not the session variable is equal to that value. The problem is that once being logged in for a short while and sending and recieving some data, the session variable resets, and I'm returned to the login page to repeat the process. Here's the basic code from my webforms:
[code]....
Is there some setting I need to change in the web.config file to adjust the cookie timeout or is that only for the config tool authentication methods?
