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.
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 6 RepliesI 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 4 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 have a listview control, in it each item will have a checklist eg - Pass / Fail which will then have a label displaying the selected value. I also have datapager wired up to the listview.
When i toggle between the datapages and toggle back, any result previously submitted will be wiped.
I am thinking i should be using session state to temporarily store then info, and then once the session is finished use a submit button to send all values and ids into an xml.
1. Is this the right way of approaching the situation?
2. How would i specify session state for listview items, eg would i angle it through a itemdatabound event or the application itself?
i have defined profile properties in my web config file but unable to access them in code behind. even profile object is not available. i have to writer fully qualified name like System.Web.Profile. below is my web config
<profile>
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.

View 2 RepliesHow to remove querystring items? Dim currentUrl As String =[URL] Remove the querystring("link") key item and it's value? It will now become [URL]
View 4 RepliesI have an asp.net application consisting of two web pages and a web service. All components are part of the same project, i.e. I have a solution with only one project. The web service queries a server and fills the information it retrieves into container objects which are stored in the cache of the application. This done using the Cache.Insert method:
Context.Cache.Insert("DemoCacheEntryKey",
"DemoCacheEntryValue",
null,
Cache.NoAbsoluteExpiration,
Cache.NoSlidingExpiration,
CacheItemPriority.Default, OnRemove);
OnRemove is my handler that writes the reason into the log file in case the item is removed from the cache. Now from what I understand this example item should never be automatically removed from the cache. Basically this is what I want: It shall stay in the cache until I explicitely remove it. Once the cache is populated by the web service one of the web pages visualizes the cache content using html. The other web site contains a button to manually kick on the web service and one button to clear the cache content, i.e. remove everything in the cache. Unfortunately somehow the cache seems to get cleaned up once in a while. In irregular intervals all containers that are created by the web service and are stored in the cache are removed from the cache. I don't understand the reason for this. The only place in the code I remove something from the cache is when I manually press the clean cache button on one of the web pages.
What is strange is that all container objects in the cache are removed, not just a few. But this is not because the button that cleans the cache is pressed. I know this because a log entry is created whenever that button is pressed. To find out what is going on I attached the OnRemove handler which just logs the reason why a cache item is removed. In my case the reason is "Removed". I simply don't get it. How can I ensure that the cache just stays as it is? Items placed in there shall just stay there. Nothing shall be cleaned up automatically.
i've been coding an asp.net site using VS2005 for about one month.
my site uses both application cache and session cache to save data.
the syntax i use for application cache is :
HttpApplicationState appState = Application;
appState["someKey"] = "somevalue";
and for session cache i use :
HttpContext.Current.Session["someKey"] = "Somevalue";
my site is deployed on three standalone servers - each server runs a diffrent instance of the site.
two of the servers work just fine, the third has a stange problem - and also has the least free memory space.
in this server items start dissapearing from both the session and application cache - note that i set no expiration date to the cache items.
does anyone know why this could happen?
seems to me there is perhaps some memory limit for cached items setting that i am missing.
I built an intranet application using code from this project (link and more details below):
Everything seemed to work during testing, but when multiple people are using the shopping cart, items show up across sessions.
For instance, if two orders are created at the same time, an item in Order 1 will show up in Order 2 by hitting the shopping cart refresh button.
Order 1 and Order 2 are two separate computers and being used by two different logins. Cookies are enabled in the browsers.
when an item is added like this: ShoppingCart.Instance.AddItem(arryProductId(i))
Should it not add that to a unique instance of the cart and nobody else be able to see these items?
We are getting ready to deploy this and this is a major issue. Any help would be greatly appreciated.

An instance of the shopping cart is created like this:
If HttpContext.Current.Session("ASPNETShoppingCart") Is Nothing Then
Instance = New ShoppingCart()
Instance.Items = New List(Of CartItem)
HttpContext.Current.Session("ASPNETShoppingCart") = Instance
Else
Instance = CType(HttpContext.Current.Session("ASPNETShoppingCart"), ShoppingCart)
End If
When I insert items, they are added like so:
ShoppingCart.Instance.AddItem(arryProductId(i))
In a page (not default) I have:
Protected
Sub Page_Load(ByVal sender
As
Object,
ByVal e
As System.EventArgs)
Handles
Me.Load
Try
loginRep = BusinessLogic.SR.GetUserName("99999")
System.Web.HttpContext.Current.Items.Clear()
System.Web.HttpContext.Current.Items.Add("RepId",loginRep)
I don't any errors and when in the run in the immediate window:
? System.Web.HttpContext.Current.items("RepId") in the immediate window on THAT page I get the OBJECT.
Then I have a hyperlink with navigateurl to the next page "~/ActCnt.aspx"
On that page, ActCnt.aspx, when in the code I have:
Protected
Sub Page_Load(ByVal sender
As
Object,
ByVal e
As System.EventArgs)
Handles
Me.LoadIf
Not Page.IsPostBack
Then
Dim loginRep
As BusinessLogic.SalesRep = System.Web.HttpContext.Current.Items("RepId")
In the immediate window ? System.Web.HttpContext.Current.Items("RepId") returns a String that is equal to "RepId".
Even if I change it to not be an object, but a string I only get the Name "RepId" of the keypair. I have NEVER gotten the actual value.
I have a multiview inside an updatepanel. in one of the views, I save a value in a session object like this:
Session["xyz"] = "some string value";
Then I switch to another view and try to pick it up the value in a button's OnClick event:
string x = Session["xyz"].ToString();
But I get a null reference error. Debugging it shows that Session["xyz"] is indeed null, yet other Session variables are still there. Is there something special about Session and AJAX?
I know how to use Profile Shopping cart property with Web site but i can't use it with web application
if you can refere me to any post explains how to use Profile Shopping cart property with Web application.
For example if i used this code in web application does not work but it works in website!

I am making progress on my shopping cart page. I want to show the contents of my shopping cart but I am puzzled on how to do this.
Here is the code :
Cart Class (Cart.cs)
[Code]....
Default.aspx ( I would like the cart to show up on a label on this page at the bottom)
[Code]....
[Code]....
We have a section of our site that allows you to add items to a cart, nothing to sell.. just keep while you are on the site and can go back to..
On the page that you have that ability to add items, i also have a label that displays the number of items.. Now that we are going to go live with this, thay have moved the count to the menu, but the menu is within the Site.Master file, so its not being populated. But it works fine on the page where you can add items..
So what can i do to accomplish the task of displaying the total number from my master file, right now you can only see the accurate number on the page you add to cart.. once you select another page, you dont have it anymore..
This is within my event for the "Add to Cart" button, this works, because the label is on this page. But now the label is within the master file and even though the below works, the number doesnt update on the menu .
[Code]....
I am trying to get a simple multi-page program to run correctly. I have everything set up, except for the "remove" function. When I try to remove an item from the list box nothing happens. Insted of trying to explain it I will show you the code...
