How are you all managing your web page state?
Anyone using complex database methods - so that a user can pick up a web experience that might have accidentally been left?
Anyone doing any complex state management for internal (INTRANET) sites? Where authentication is not an issue?
I'm looking for alternatives to simple SESSION() vbls.
Is there any alternative of Crystal Reports. I dont want to use it....Crystal Reports are just useless,But I didnt get any other alternative!
View 4 RepliesI've created a whole bunch of rather complex classes and now i'm starting to work on the ASP.net user interface. Basically the user will open 1 page which will be used to load, edit, save an object. The object has many fields and they are often other classes i've created. To create a nice interface i've used popups and used AJAX to reload parts of the page to avoid reloading the whole thing.
My plan was to create the object and save it to the session. Then each time the page is loaded copy the object values to the asp fields and do the reverse when the page has been submitted copying the asp values to the object field then updating the session object.
So the code will go something like:
onload:
if session is not null load from session otherwise create new
this.txtID.text = object.id
this.txtName.text = object.name
etc etc
on submit:
object.id = this.txtID.text
object.name = this.txtName.text
etc etc
update session.
Is this what you guys would do? or am i over thinking this, seems like a lot of code to load all the object fields each time the page is opened and submitted etc.
Just looking to bounce ideas of off other developers :D
My prior asp.net apps used windows authentication on an intranet. Now I'm developing an app for the internet and am stumbling over how to properly manage user sessions and state.
I first developed my web site functionality; created the SQL DB and got all of the pages to properly handle the data. Then, I installed the SQL Membership database and was able to get the CreateUser, Login, Logout pages to work. On the Verify process for the Userid, I added a step that will take the membership UserId value and create a Company record in my tables and link my CompanyId key with the UserId.
At Login time, I create a CompanyId session variable; each page uses it to retrieve records for the user. When Session Timeout occurs and the user click a link to another page, the app redirects properly to a Login page. However, if the time expires and then the user interacts on that same page, 'Object not set to an instance of the object' - the CompanyId session variable has expired.
What is the proper way to handle this? I'd like the page to automatically redirect to a TimedOut page (this would happen automatically without the user doing anything).
I considered writing a Function where I pass the Session variable I want and the Function sees if it exists; if it doesn't it would do a Response.Redirect to the TimedOut page...I can't get the Redirect to work in a Class Function ('reference to a non-shared member...').
I assumed that I should set CompanyId as a Session Variable so each page knows the user to get data for. Another approach is to use the membership User and if it is still valid, do a DB lookup to get the CompanyId. I did not choose this because I felt that it would increase DB traffic and web traffic.
Here are several relevant settings from my web.config:
<sessionState cookieless="UseDeviceProfile" />
<authentication mode="Forms">
<forms loginUrl="~/UserTasks/Login.aspx" />
It feels like there should be a straightforward answer to this but I am missing it.
we are working on a huge project(web application) in asp.net ajax & c#. Per day 300 memmbers will access our website for data entry.we are using mssql 2005.we implemented someany sessions in our project.now our application becomes very slow.We are planning to remove the sessions in our project.

I'm using VS 2008, C# 3.5 to develop my own login system for our company website.
Originally we have a "simple" design which only had a login and order page.
That order page needs to be opened for 10-12 hours at the time while our stores are opened without having to relog into the system for each query.
We also have a requirement that some users need to access 2 different compagnies (separate inventories) which require 2 different logins.
I solved that "cross over" session problem by moving all the values into viewstate with my own viewstate manager class right after the login.
Now my problem is that we are adding more and more pages and I don't want to be stuck with the problem to resave the viewstate to session and then back on viewstate for every menu items and buttons.
Is there a way to create some sort of items list of all the sessions opened by the user and only transmit that from pages to pages?
We have used Session heavily in our application, we have created core classes (which have many properties) and store objects of core class in the session.
1) What could be the best solution for reflector activity?
2) What could be the best way to manage session in an application which has 100 pages?
I am trying to create a system in which there will be a single user accessing his acount from two endpoints simultanously.
I think this is possible.
1) How to restrict the user to have only one session at a time?
2) How to change it to have limited number of sessions per user at a time?
I have a problem to manage session variable in to different virtual directory. I need to access Session value from one virtual directory to another virtual directory. For Example I have a Web Site in my IIS with one page. Page 1
[Code]....
I have another virtual directory under the same Web Site with one page as follows.
Page 2
[Code]....
I can't access session value of Page 1 from Page2!I need to access Page 1 Session value from Page 2.
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?
View 2 RepliesI feel like I am fighting against the current when I develop ASP.NET Webform apps. I frequently run into the same problems, and while I eventually find some kind of workaround i'm never fully satisfied with the results.
Here is an example of a typical problem:
The design requires a grid or grid-like result set. This result set is pulled from a database, however, there are additional controls on each row that are not data bound, but their contents are used to insert data into other records.
A good example of this would be displaying a list of products, then adding selected products to a shopping cart based on values entered into quantity fields, and options selected per product. Throw into the mix that you have to allow multiple lines to be added to the cart at the same time, and it starts to get more complex.
Let's add to that mix that you can't select certain products together (mutually exclusive), that you can only select a certain number of one product, but not another, that prices may change while the user is selecting their items, that you you get an overall discount per item based on quantity purchased (both per item and overall order), that you are using a line of credit and cannot exceed the line of credit, nor can you buy more of a given item than an arbitrary amount set in your account or in the product by your account representitive (think certain over the counter medications that the government limits how many you can buy), etc.. etc.. etc..
What starts out as a simple grid with an add to cart becomes a hopeless mess of business logic, which then of course requires validation and notification to the user of various errors in their choices.
How does one deal with very complex data entry schemes in asp.net? How do you even begin to design a piece of software to do all this?
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.
View 3 RepliesI am using a datapager on a page where different images are shown. Now i am using the following code:-
PHP Code:
<asp:DataPager ID="DataPager1" runat="server"
PagedControlID="lvPhotoViewer" PageSize="1"
onprerender="DataPager1_PreRender">
<Fields>
<asp:NextPreviousPagerField ButtonType="Link"
PreviousPageText="<< Previous" NextPageText="Next >>"/>
</Fields>
</asp:DataPager>
Now this code does run through all the images, but i need to alter the querystring and make it change to match the ID of the photo displayed. I tried adding QueryStringField="String" but this was hopeless.
I have a querystring like so:-
Quote:
[URL]
When i click on next image i need it to change to something like:-
Quote:
[URL]
See the PhotoID has changed. But it currently does not do this. When i arrive on the page the PhotoID stays the same. I have been trying for a while and im starting to give up!
So was wondering if there was an alternative.
I have a question about viewstate:I have created a simple little website in 2008 (.net 3.5)I have one page with markup that looks like this:
[Code]....
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.
I am developing a new project to list files and directories under an specified location on disk. I use normal methods like Directory.GetFiles() to achieve this task but the amount of files is getting very big (> 300000) and the site is becoming terrible slow.
I worked with Index server with previous versions of Asp.Net but I was wondering if there is a new way for my website running Asp.Net 4.0.
Also I heard something about Index Server is obsolete to achive file listings and search. Is there any new alternative?
Quick question: Is there a "per-user" data storage object (similar to Session) that I can store data in the global scope (similar to HttpRuntime.Cache)? Almost as if Session and HttpRuntime.Cache had a baby.
Full Background: I have a ASP.NET website that was originally written for a single thread. Now I changed it so that certain actions will spawn a background thread and the browser polls a service to get status updates.
The problem I am having with this is that certain pieces of data are stored into the HttpContext.Session[] object (membership authentication token, for example). These pieces of data need to be unique to each user and accessible to the background thread. Session is not available to the background thread.
I am aware of HttpRuntime.Cache but that would require micromanagement to segment out the users and to expire it at the same time the session is expired. Session, on the other hand, automatically expires this things at the right times that I want it too and is already used by things like the SqlMembershipProvider.
My question is, is there something that behaves similar to the Session but exists in the global scope?
I am working on a Report Module for a DNN website and have found that the reports do not show in the reportviewer control if there is no ScriptManager control on the module. I am not sure where but somewhere I read it was needed. THe problem is when it is on the module so the reportviewer works correctly I am getting some errors with my other controls( mainly drop downs I want to use for selecting the reports) I am not getting an error just the DDL is not showing up on the page when scriptmanager is included but it does show up when its not included of course then the reportviewer shows no report.

I create a menu control in a user contol, named as RightUserrControl.ascx.
and i kept this RightUserrControl.ascx in nearly in 200 pages.
every thing is working fine , but when ever i am going to any page the page loading is very slow, nearly each page is taking 1 minute to load.
set caching for the user control, if this is the case , do i need to declare output cache in all 200 pages or is there any alternative way to resolve this issue.
nvironment : [Asp .Net Application in Visual studio Team System 2008 + SP 1 ]+ Windows 7 Enterprise + IE 8+ IIS 7.5

As a workaround for the fact that asp:Checkboxes don't have values, I am attempting to dynamically create the ID's of checkboxes in a DataList so that it inserts the primary keys into the control ID. This is surprisingly difficult.
I have placed a PlaceHolder in my DataList ItemTemplate, then in the ItemCreated I create the checkboxes using string.Format("Checkbox{0}", DataBinder(e.Item.DataItem, "ID")). The problem is that this only works in a non-postback condition, as on postback the DataItem is null. And of course ItemDataBound isn't called on PostBack so that won't work either.
I can't seem to find a good way to handle this short of if (IsPostback) dataList.Bind(), which i don't think is a good way to do it.
Can anyone provide me with any alternatives here?
In my Application I am using one Modal popup extender. I have one Grid View with Item Template containing Link button. I want to set Target Control Id of Popup extender to link Button of the Item Template. As it is inside the Item Template I can not access it directly in the page.
So Is there any alternative to achieve the same functionality.
