State Management :: Session Variable Disappears When Leaving Page?
May 14, 2010I have a session variable which contains a list of elements. The user defines filters, which are sent to the Database, which fills the object with the elements that match. Then, that list is shown in a table. The code goes something like this:
[Code]....
Inside that page there is a button, which sends the request given the user filters. The Server creates the object and the session variable is assigned a value.
[Code]....
It works when the user sets the filters. However, given that once done it, the session variable has a value, I don't understand why if you navigate to other pages, the table doesn't appear when you return, given that:
1. It works when you perform the query and reload the page
2. The Session variable should be set for the rest of the session

State 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.
View 2 RepliesWeb Forms :: Warn User When Leaving A Page With Changed Data?
Jan 28, 2010I'd like to know how I can warn a user when they're leaving a page where they've changed data (i.e. "You have unsaved data on this page, are you sure you want to abanon it?"). For example, the page has a few dropdown lists, some textboxes, etc. I'd like to warn them if they try to leave the page before saving the data. How can I do this? To add to my confusion, I also have a dropdown menu control (skmMenu) on the page that doesn't seem to have any events I can tie into.

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.
State Management :: ViewState Returning Null On Postback?
Apr 18, 2010Im currently experincing some difficulties with the viewState. The scenario is that i have a datagrid that has a column of buttons that when pressed will store a value in the viewState. I have already done this on one occasion in the same page, but for some reason the second item in the view state is always returning null, even when i hardcode in a number in before the postback. Im at a loss as to why this is happening, anyone expericened this and know what is wrong.
EDIT: Ive found out the cause, Its due to when you click a button in a data grid it does the postback code first, then fires the event handler, so of course the view state would be empty as it is coded to be set in the event handler for the button click. Is there any way to avoid that? So the event code is fired before the postback code?
