I am trying to incorporate AJAX in my web project for the first time and it isn't working. I don't know how to instantiate a class once and use AJAX to update the dataset numerous times before updating the database changes using a postback.
My project is to learn AJAX with a class object. Clicking the button is supposed to increment a count by one using a class to store the count. Here is my class:
[Code]....
Here is my HTML code:
[Code]....
And here are my button click event code snippets:
[Code]....
My problem is that as I step through the code (after clicking on the second button) it instantiates a new class object each time which returns a value of 2 every time. I have tried to fix the problem by putting my counter class instantiation in the pageload event using "If Not IsPostBack Then ..." but my probem there is that the button click event block of code would not recognize the cCount class - it put the blue lines under the cCount
My goal is to have the class object available to multiple events in the code behind: especially using AJAX to build records in one of my DataSet tables Does anyone know how to handle this?
I have a website for a simple game. When people sign in their Player ID is stored in a Session variable. I have integrated SMS payments so that my players can buy credits to use to play. This is where the problems start:
To buy credits, players are presented with an .aspx page that holds an IFRAME of the SMS payment proviers form. A code is entered, and the IFRAME POSTS to a URL on the providers server. It is then redirected back to an URL on my server(www.XXX.com/process.aspx), where I handle the results (i.e adds credits to th players account if the payment was successfull).
However, the session dies on return.
I tried with cookies, and saves the player ID in a cookie, but when upon return to www.XXX.com/process.aspx I cannot read the cookie? I'm checking for if (cookie == null) and it evaluates to TRUE, so the player is redirected to an error page.
How come the cookie cant be read? Is it because the POST is coming from an outside URL? And, what about when I do it with a session variable? Same thing there?
I am looking for an elegant (i guess as elegant as it can be) solution to caching a users profile on login (whether it is session, cache, cookie, etc) and keeping it in sync when a users profile is changed. How do you guys handle this? Just simply call a Flush() method in your Save() method that invalidates the cache?

View 1 RepliesI need to implement the following feature for a shopping cart using profile:
1. User opens the site from Computer A and selects items which are added to the shopping cart. Now suppose the User logs in the same items should be displayed in the shopping cart as before he logged in. Now say he adds some more items to the shopping cart and logs out, then the items he added newly should also be displayed in the shopping cart.
2. If the same User as in Step1 opens the site from Computer B and logs in there should be a different profile entry for him and he is not to be shown the items that were selected in the shopping cart in Step1.
I feel I need an implementation of the profile on per user+ computer basis for logged in Users. We have this kind of requirement for a B2B site where companies will have only one common login and it will be used by many Users to order items.
I've done a bit of searching on this subject and haven't found anything so far. I am successfully using the Profile object and am saving Profile records away into my SQL Server Database. I have checked using the stored procedures and viewed the individual records to know they are there. However, I want to create a WebForm that can enumerate through all of the users in my Membership DB (Same DB as the Profile DB) and list each user in a grid showing what values each user has within their profile. For example:
Username
Profile Element 1
Profile Element 2
Profile Element 3
bob
true
false
true
fred
true
false
true
I want however to replace the 'Profile Element 1' etc etc to display the actual name of the Profile. I would like to do this programmatically so I don't have to recompile the website everytime I add a new Profile element.

I had an xml-serialization which worked fine, but as I have just knew it doesn't work in Opera browser. I think, it's security rules don't allow to write to cookies xml-content.What can I do? Can I use binary serialization or something else?
View 2 RepliesAnyway, I currently have a ajax based progressbar, which works like this: my long-task stores progress in session. Async callback retrieves progress from session, progressbar is updated. Everybody is happy... not! This only works when the "main loop" of the time-consuming task runs in either codebehind or a class with httpcontext. But all my businnes objects cannot do such thing. So, the next natural spet would be to say "move it to a static class" ProgressHelper or something, but since static classes are shared across all appDomain, I would bump into concurrence problems. So, can i have say a "static list progress" say progress["session1_progress"], progress["session2_progress"], progress["sessionN_progress"]? I cannot really see a way to update progress from inside a task in a business object, which i might want to use also in other plattforms like a desktop app?
View 7 RepliesI wish to persist a class object across postbacks by using a single session variable/object/whatever.
The class has about a dozen single variable properties; and about a dozen table properties; and several methods. The main table tracks rows of sporting event results. The web site will collect one row at a time for each postback. The data in the object's constructor is based on a dataset, but the data in the class will grow each time I do a postback so I don't want to loose the information in the class. The data isn't very big - it will fill a single computer screen.
Being new to programming I am thinking that I can store the dataset in the session but that would slow down the response time because I the methods would have to be called to refine the data - or maybe I can just store the entire class object in a session.
I am working with asp.net mvc and i am trying to get acces to a object that is in the cache.In the Application_Start() of Global.asax.cs i create and store an object in the cache like this:
Translator translator = new Translator();
HttpContext.Current.Cache.Insert("Translator", translator, null, System.Web.Caching.Cache.NoAbsoluteExpiration, System.Web.Caching.Cache.NoSlidingExpiration);
Translator holds a dictionary with translations.Now i want acces to this object from the cache to use functions and get values from the dictionary.I know i can acces it like this HttpContext.Current.Cache.Get("Translator") or Cache.Get("Translator") in the views But how can i use the functions of the object ? The meaning of the cache is to have a object that is accesable througout the webapp right ?
Do i have to make an object and asses the value of the Cache.Get("Translator") to it, so i can use the functions or is there another solution?
On my local machine I've got a website running which uses the login control to authenticate a user and write a formsauthentication ticket to the client (which is also on the same local machine). At the login process it stores a a small serializable userobject in a session object named Session["appuser"]. Now when I open FF and login to the website all is fine so far... But here's the thing I cannot for the life of me figure out...
When I open IE8 and login to the same website, the session object which was created in FF is completely overwritten with the one created in IE. I thought that every session is unique, but now I'm really starting to feel my knowledge of sessions is almost next to nothing... Is there anyone out there that could tell me why I'm seeing this.
how I can know if a session object was never instantiated?
