The problem with Application state is, it's for the entire app. So if you have more than one user, the information stored is for all users, not just the one you're focused on.
Was cross page postback on the list ? Why can't you pass information between pages by forming the appropriate query strings ?

Complete list of options and explanation:
Control state
Application state
Session state
Cookies
Viewstate
Query strings
Hidden fields
Correct answers: Session and cookies
EXPLANATION:
Session state can be stored in a central state server or in a Microsoft SQL Server database. Therefore, by configuring multiple front-end Web servers to store Session state in a single server, a user can move between Web servers without losing Session state.
Cookies store all information on the client, rather than on the server, placing no server-specific requirements on the Web application.
ViewState, ControlState, and hidden fields can be used only to maintain state for a single ASP.NET form. You cannot use them to track settings across multiple Web pages.
Query strings require adding parameters to every link the user might click on your site. Therefore, it would be very difficult to ensure that every link was dynamically generated to contain state information.

Not to share data between servers. Each server is running a separate instance of the application.

Hi,
I wrote an asp app and when I deploy and run it on the server, it will run up to a point then issue a timeout error along with some Event Viewer messages.
When I run the app from my VS IDE, in Release mode the app runs happily without any errors and using the same exact data parameters and settings.
I know that when running from IDE in Debug mode, the debug=true param is set, but I'm running in release mode and I understand that debug=false in that scenario. But regardless, I set debug=true when deployed and it still errors out.
web.congif has session timeout and httpruntime timeout set to over 20 minutes and I also found a trick here on codeproject top keep the page session alive. My sql calls in the app also have high timeout settings.
Can anyone think of why an asp app would run perfectly through IDE and not in production?
If the errors I got were a bit more verbose I might be able to do something with them, but they are not, just says Timed Out.
Thanks in advance for any help!!

Hi All,
I am hardly few months old in asp.net. My current project requires to list the folders (rootfolder) in a treeview. I am using VS2003 and thats the trouble all about. I guess it is easier in VS2005. I did a lot of research and found various codes from the web, however, when I write soemthing with a "Tree" like "TreeView", "TreeNode", "TreeNodeCollection" etc it displays a wiggly line below it. What is the namespace to be included? what am I missing....Someone please explain all this to me together with the code at the earliest....Any help in this regard is highly appreciated.
Regards,
Rinjin

We have deployed three applications(three different virtual directories) having the following settings for SSO.
Forms Authentication-Settings are similar in all the applications
MachineKey entry is kept similar in all the web.config.
The authentication cookie is not persistent.
SSO works well in IE. When the user opens a new window, it asks for the user to log in. When the user navigates to other sites from the same window, it doesn't ask for log in.
In firefox, even if a new window is opened, it doesn't ask for log in and logging in automatically.
Please help.

Try given following options:
Add this in Head section:
<head>
<pre><meta http-equiv="CACHE-CONTROL" content="NO-CACHE"></meta>
OR
on Page load method:
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetAllowResponseInBrowserHistory(false);

actually I want to clear history for particular page only not all history.
I applied
<meta http-equiv="CACHE-CONTROL" content="NO-CACHE"></meta>
in master page
and
in page load in test.aspx.cs page
Response.Cache.SetCacheability(HttpCacheability.NoCache);Response.Cache.SetAllowResponseInBrowserHistory(false);
but still it's going back by browser.
thanks

You can't using ASP.NET. ASP.NET runs on server and emits HTML for the requests. It can't access client's computer and delete history.

If you have no idea how to do this, you either have not read your book, or you have not bought one. Either way, the process is too complex to answer in a forum post. Buy a book, read an article, come back if you've tried to do it, and have a *specific* question. That's where these forums are better than google, not top level 'I have no idea where to start because I haven't looked' questions.
