i am currently storing my shopping cart in a datatable assigned to the session. but i wanted to know is it a good idea to store the GUID for the session shopping cart?
View 6 RepliesI m developing new shopping cart by using mvc2.and i have followed sample video store application posted in asp.net.my question is: What is the best way to keep shopping cart data.is it in db or a session.
View 3 RepliesI'm creating a shopping cart application and I'm having some issues with implementing a session state for my arraylist.
in my page load i declared
if (Session["Cart"] == null)
{
Session["Cart"] = new ArrayList();
}
else
{
ArrayList cart = (ArrayList)Session["Cart"];
}
to create the session if it doesn't exist yet.
then i have an event handler for a button to add items to the arraylist
protected void onClick_AddBooking(object sender, EventArgs e)
{
int ClassID = Convert.ToInt32(Request.QueryString.Get("Class_Id"));
ArrayList cart1 = new ArrayList();
cart1 = Session["Cart"];
cart1.Add(ClassID);
I'm essentially storing the class_ID then when the student confirms i'll store that to the DB and associate that ID with the Class Details.
I 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 am working on a Railway Portal and would require maintaining a shopping cart of components user has selected, there could be multiple components of different type in the cart. I don't see a value in storing the cart in database, would like to store the final order in DB. Where can I store/hold (temporary) the cart data per user session in MVC? All MVC samples I saw online save the cart data in DB - not sure why.
MVC presentation layer will be communicating with external web services for pricing and availability of these components, so I can't store only the product IDs to do a lookup for actual product descriptions/prices during the shopping process... I have to store everything in the cart (Product IDs, Descriptions, Prices etc) some place in memory. My application will be running in WEB FARM environment and cannot use in-process session storage.
Options come to my mind are:
SESSION STATE in SQL SERVER Using some kind of Distributed Caching Mechanism to store Session data such as "Windows Server AppFabric"
I have created a shopping cart where i currently store items in a session but i want to get away from this.
so i am going to store it in a list.
how can i create a custom class for this and store the values everytime items are added.
the purpose of using Profile in asp.net. I would like to know the usage of profile in shopping cart based sites.I could see from some of the cart websites that profile plays a major role for online shopping projects.It is better to know how this profile to create opnline website and which websites or example to reach the technologies as well.
View 1 RepliesI am working on a site in which some pages are to be run on secured server(ie https) & some on non-secured(ie http) eg Login, User Information, etc. will be run under https & View cart, etc. are to be run on http. Now, when user chooses some products in his cart, he is prompted to enter login details. After he fills in his login detail(ie in https), he is redirected to Checkout. But here the Session doesn't picks the value and it shows Session[UserID] value null. So, rather then redirecting to Checkout it shows MyAccount page. Does anyone know how to pass Session Value from https to http.
View 3 RepliesI know there are a million questions out there on how to implement a shopping cart in your site. However, I think my problem may be somewhat different. I currently have a working shopping cart that I wrote back in the 1.1 days that uses ASP.NET session variables to keep track of everything. This has been in place for about 6 years and has served its purpose well. However, it has come time to upgrade the site and part of what I have been tasked with is creating a more, erm, user-friendly site. Part of this is removing updatepanels and implementing real AJAX solutions.
My problem comes in where I need to persist this shopping cart over several pages. Sure I could use cookies, but I would like to keep track of carts for statistical purposes (abandonment stats, items added but not bought, those kinds of stats) as well as ser-friendliness, like persisting their cart so that if they come back it is remembered. This is easy enough if a user is logged in, but I don't want to force a user to create an account if they don't want. Additionally, the way we were processing orders was a bit, ehh, slapped-together. All of the details (color selected, type selected, etc) are passed to paypal via their description string which for the most part is ok, but if a product has selections that are too long for the string (255 chars i believe), they are cut off and we have to call the customer to confirm what they bought. If I were to implement a more "solid" shopping cart, we wouldn't have to do that because all the customer's choices would be stored, in addition to the order automatically being entered into the order processing system (they're manually entered into an excel spreadsheet. i know, right).
I want to do this the right way, but I don't want to use any sort of overblown software that won't really work with our current business model. Do I use a cookie to "label" each visitor to match them with their cart (give them a cookie with a GUID) across pages, keep their whole cart client side, keep the cart server side and just pull it from the db on each page refresh?
In my online shop, users can search products,each product have a link called add to shopping cart, users can add to the list many products like anonymous user, the question is.How can i do,for not to lose the product list, when user make Log in or create one account in my site

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 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.

View 2 RepliesI have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.
