State Management :: How To Store Data From DataBase Like XmlNode

Sep 21, 2010

i am building an N-tier application now i want to store Data(like XmlNode) that is common to all users ..

now i thought using Application to hold the data but my data lays in the BLL tier which is an Class Library project and i can't store any datain there for example :

HttpApplication MyApp=new HttpApplication();
MyApp.Application["Data"]=XmlNode;

My question is what is the best way to store Data (not small data like user name etc..) is it Application? orCache?

i would like a small example within a ClassLibrary project

State Management :: Variable To Store Temporary Page Data?

Sep 29, 2010

I'm working on a web page that is going to be used to enter data into a database. The page is going to be dynamic in that the user has the ability to add a row to the table with the same fields, ie lname1, fname1, mi1 then lname2, fname2, mi2

I'm wanting to use a variable to keep track of how many lines there are so that when I generate the added line I am creating a new field with the ID of lname+# . Whats the best way to do this, a global variable, session variable? As side note, first time programming in .Net or C#.

Sep 29, 2010

I need to store a large amount of data in user's session but I guess using Session Object is not the best way of doing that. Is there any other way around??? Remember I don't have small variables to store, I have large collections.

State Management :: Best Way To Store Users Mail Address?

Sep 8, 2010

I have some webforms and the main page grabs the users email address when they login and a UserID. It's not uncommon for the user to keep the web page open all day. Is it good practice to store the email address and ID as a session variable and up the timeout to say 10 hours? Or is there a better way? My concern is A) Session variables timing out before the user login timesout B) Doing this incorrectly.

Guid

CType(Me.ViewState("myGUID"),
Guid)
End
Get
Set(ByVal

State Management :: Store Viewstate In Session ( Framework 3.5, VS 2008 )?

Nov 9, 2010

I need to store viewstate in session to optimize my page performance on postback.

I am developing ASP.Net Website, using Visual Studio 2008.

I created a class named "BasePage" under "App_Code".

[Code]....

Now, I know if I inherit this class in all of my pages, that will work but I am looking to do this through Config file.

Is there any way that I can write something in Config file to use this class for all the pages?

so that if I want to remove, I can simply remove from config file and I do not need to compile my whole project again.

State Management :: Build Up The Order Query From The Selections Made And Store It In Db?

Jan 11, 2011

I am building an invoice system for a client and I am having trouble with the web forms related to the INSERT new order query.Basically I want to build up the order query from the selections made and then store it all in db at the end.

I don't want to use temporary db storage because it's a wasted trip to the server, I don't want to use session state because it's not data about the user I'm storing.... Unless I'm wrong, from what I've read I think query string is my best method since the data is not sensitive, it will just be primary keys and the like.

On the first form, the user will select the customer id from a datagrid displaying all customers. The next form allows them to choose the product from a datagrid showing all products and so on.... How do I pass this information across several pages?

My hope is at the end I will be able to take all the values and insert them into the corresponding tables to make up the customer order.

Apr 5, 2010

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?

Apr 1, 2010

Im working on my first ASPX webpage now, and Im wondering if there is some way to make a cache?

With a cache, I mean a list of variables that gets transferred from a db to for insance a hashtable the first time a user loads the page. When the next user loads the page, the db doesent get touched, but the variable is collected from the hashtable.

I tried to make a static class, but it re-loaded for each time I refreshed the page.

State Management :: SQL Database - Cache Expires The New Data Is Picked Up?

Dec 17, 2010

I'm running a website on a SQL 2008 database. At the moment most of my data is in cache but what I want to do is be able to update the data on a regular basis, say every 3 hours, maybe more frequently. Obviously I can set the cache to expire and pick up new data, but how can I replace part of the database (because some tables are populated by the user) in the background, so that when the cache expires the new data is picked up?

I notice when I upload data through VS, it wont let me upload if the DB is in use - so how do I get round issues like this?
