Web Forms :: Items Getting Removed From Cache Earlier Than Specified Expiration Time
Dec 26, 2012
I wrote this code for inserting Items in shopping cart and I expect one day Shopping Cart Items be available.

{
ShoppingCart cart = new ShoppingCart();
[Code].....
and I face another problem that I think it's related to above problem. I have a cateogry of product when I click on a category I send categoryid via querystring to another page and fetch iformation about that from database and bind them in repeater this is first line of code
I have asp.net application. I'm using external javascript files in my application. When I test my site with page speed tool from google it says that following resources are missing a cache expiration. also some of the images and css files.
I need to remove the data stored in the cache after few minutes (Output and Data Cache).
My concept is binding data from server, storing it in to cache and displayed in the gridview, after a 10 seconds when the button is clicked the cache data should removed and need to show null like nothing. I have build some basic of code, how to get perfectly. I am new to dotnet.
find the below required points and attachments of asp.dot net code and sql query.
1. When page load, gridview should display using Cache.
2. when Clear Cache Button after 10 second from pageload is clicked then the gridview should go hide
3. Reload Cache Button is clicked the gridview again load.
I have a scenario in my application that I need to display session expiration time to the user. I set session expiration as 30 minutes in my application, 5 minutes before the session expiration, I need to show message to user that the session is going to expire.
How can I will do this implementation, I am using VS 2010 + MVC 2.0 + JQuery.
App is imported in the parent web.config file, Tom and App have classes with the same names.To avoid errors resulting from ambiguous class names I removed the App namespace from the sub-directory where the Tom namespace is used.
However the namespace App is still imported on content pages that have a master page outside the Tom directory. This causes the aforementioned errors.Here is my dir structure
-Root Directory --Default.master --web.config (App is added in web.config) --Tom Sub-diretory ---web.config (App is removed in web.config) ---Content page that uses Default.master (Here is the problem) ---Page without master (Works OK)
I have trouble with the sequence of events on my page. I have a button, which on its onClick event calls a method, which posts data to a database, and causes a postback. But on the same page I have a repeater which uses the data that is being modified by the button. I would need somehow the buttonclick event occur "earlier" than the databinding in the repeater to show the correct data.
I have a music related ASP.NET web site which caches a lot of static information from the database on the first request.Sometimes, the application is reset and cache is cleared while the application is on heavy load and then all http requests go to the database to retrieve that static data and cache it for other requests.
How can I ensure that only one request go to the database and cache the results, so that other request simply read that info from cache and not needlessly retrieve the same info over and over again.Can I use thread locking? For example, can I do something like lock(this) { db access here }?
What is the best method to cache the following? I am creating an intranet web application template that will display the message, e.g., Good Morning, Justin Satyr! near the top of my master page header. Obviously, I will have to determine whether to show Morning, Afternoon or Evening. For clarity, my code is below:
I do not want to re-determine this on each page load because that seems moderately redundant and because I have to poll a SQL server to retrieve the user's full name. What is the best way to cache this nformation? If I cache it for the length of the session, then if the user begins using the application at 11:00 AM and finishes at 3:00 PM, it will still say Good Morning. Is the best thing to do simply re-determine the M/A/E word each page load and cache the person's full name for the session? Or is there a better way?

I've noticed that page load time increases dramatically as you load up a ddlistbox with items. 10,000 or so results in a pretty much unacceptable wait time for my setup. The dropdown I'm trying to load is Airports - like all of them. What are some alternative UI solutions that give the user the ability to easily select any (literally) airport, but without a ginormous page loading time? (Currently the dd is keyed to the airport's 3 letter code, so it's convenient for the prepared user to just type the 3-letter code and have the right airport selected. The display is then set to code, city, country.)
I have an ASP.Net 4.0 web application which very frequently loads data from the database and does heavy calculations on it. I want to cache this loaded and prepared data in a central cache that can be accessed by every user and computer who uses the application.
Simple use-case:
User 1 accesses webpage, cache is empty, data is loaded/calculated, data is cached User 2 accesses webpage, cache contains data, data loaded from cache User 3 accesses webpage, cache contains data, data loaded from cache User 1 reloads webpage, cache contains data, data loaded from cache Cache expires User 3 refreshes webpage, cache is empty, data is loaded/calculated, data is cached
I know that ASP.Net has a built-in cache mechanism. What I don't know is whether it can be shared between different users accessing the site on different computer at the same time. I would also like to know how the system behaves in a web farm environment.

I have a form that has contact fields, billing address, and shipping address. So if i fill out my contact information ONLY and left billing and shipping address blank then hit submit, the validation for the billing address and shipping address appears. Ok no problem, there is a check in each billing and shipping fields that once click on it copies the address from contact to billing or shipping fields. Everything works except for the validation messages. They are still there. Is there a way to remove the validation message after the textboxes are populated with data?
