Web Forms :: Session Expires When A Modal Window Is Opened?

Jun 4, 2010

I have Page1 having Button1.

Page2 having Button 2 and an ascx control UC1. UC1 has a Button 3. Page2 is a modal dialog ( window.showModalDialog )

on Click of Button1 open Page2(modal dialog).

Page2 has UC1. UC1 has a button B3. On click of B3,instead of directly going to B3_click event, another post back happens. Thereafter opens login.aspx in another browser ( It is losing Session containing UserDetails as well as other session details).

now even If I continue entering Username and password, page2 reloads again in the new browser.

I am totally lost.

1) I do not know why UC1 button click makes another postback and thereafter opens up into another page losing all the sessions!!

I want to retain teh sessions till i go back to page1.

C# - Session Transfer Between Window And Modal Dialog?

Oct 18, 2010

I have a parent window from which i open a modal dialog on button click. In WinXP with IE8 it works just fine, but in Win7 with IE8, upon opening the modal dialog it brings me to the login screen. If i enter my credentials, close the dialog and open it again, it works.The explanation i figured out is that the session isn't transfered between parent and child.The modal is opened with javascript window.open function.I don't want to store the credentials in a cookie and then read it in my modal because it's a security no-no. Is there an explanation why this is happening in Win7 and not in XP and is there a resolution for this issue?

Display Message To User When Forms Authentication Session Expires?

Oct 21, 2010

I simply want to display a message on the login page when the user is automatically redirected there after requesting a page that they were logged in for but their session has now expired. So essentially if the user was working but stepped away for a lunch break without logging out I want the system to tell them why they were sent back to the login page.

Something like "You have been idle for too long so you must log back in".

This has to be easy I am just running into a wall here. I thought about getting the original ticket and reading the expiration date but I'm a little lost.

AJAX :: Filtering Data While A Popup Window Is Opened?

Mar 26, 2010

I have a parameter page in asp.net consisting of many parameters. I am using ajax and filtering the values of the parameters based on the hierarchy. For example, only those branchs appear of a department if a single department is selectd on the listbox.

I also have a link button on my parameter screen which opens a popup window with a listbox in it. On the popup window, i select some listitems which i pass through the session into parent page when the popup window is closed. Till now, my popup window gets all the values from the data source to fill the listbox.

What i want now is to show only the filtered values on the popup window based on the selections made on the parent pages' parameters.

State Management :: Timer - Session Never Expires?

May 2, 2010

I am using a timer in the master page of my web site in order to keep a 'status bar' up to date with all sorts of information.The issue is that the whole point of session expiry goes to waste, because a postback is always being made (although asynchronic) to the server.

How can i still expire the session after a wanted period of time?

Session Expires And User Is No Longer Valid?

Aug 3, 2010

I cache information about the currently logged in user in the session. This info lazy loads whenever a CurrentUser property on my global application class is used. It does this by calling GetUser() on my custom implementation of MembershipProvider, which either loads the user up from the session, or loads the user from the DB and throws the user object in the session.

How should I handle this scenario?

User logs in. Administrator deletes user (or deactivates...the point is they can't log in any more). User's session expires. User navigates to a page or makes a request, or whatever.

Currently if this scenario occurs, NullReferenceExceptions are thrown all over the place, because the ASP .NET framework calls GetUser() which returns nothing because it can't find the user in the database (and there's nothing in the session because it expired).

How To Handle A Postback After Session Expires On Site

Mar 18, 2011

I have a simple ASP.NET 4 site. I am using Forms Authentication. I have Session timeout set to 20 minutes. Also when the user authenticates I set the AuthenticationTicket to expire in 20 minutes. So normally everything works fine. If there is more than 20 minutes of inactivity and the user requests a page on the site they are redirected back to the Login page as I would expect.

However, let's say that the user is on a page that contains a form. Then they wait 25 minutes. Then they go to submit the form. Instead of being redirected back to the Login page, the site attempts the postback and I immediately get errors because there is code in the postback that attempts to get information out of Session.

It seems like ASP.NET does not redirect back to Login on postback if the AuthenticationTicket and Session has expired. How can I handle this? I hope I don't have to write special code on each page.

ADDED: web.config code

<location path="ForgotLogin.aspx">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
<system.web>
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx"></forms>
</authentication>
<authorization>
<deny users="?" />
</authorization>
