AJAX :: Send Requests Every 10 Seconds In Order To Check It?
Jan 30, 2010
For example: If user "Tom" is logged-in now and observing page "1.aspx" I want to know about it. I also want to know when "Tom" stop observing that page. He can move to another page, than I know by server page request he is not any more at page "1.aspx", but what if he moves to another web site? Or closing his browser?
How can I know he has stopped observing that page.
I think I need to send Ajax requests every 10 seconds in order to check it, but what kind of request?
This works in other browsers but not in chrome. I am trying to allow users to upload large files and have an ajax call to update them on the progress of the file upload.
So a unique ID is generated on the client side and added to the action of the form before sending. Then the form is submitted (form only contains a file upload input) and an ajax call is made to get the progress of the upload. The ajax call goes to another page and uses the ID to lookup the upload.
I am using JQuery 1.5.1. Debugging this and putting something on the error function give me nothing other than "error". Not very helpful. I used Chrome's debugger and it just says failed to load resource xxxx.aspx. xxx.aspx is the URL i needed. Turns out that there seems to be some sort of conflict between the form and the ajax call.
I'm working with asp.net c# web application. We have completed site and hosted in dedicated server (own server).
This server having only one site (sharepoint site). A page having 1000+ images. Loading in base page. And slide show in popup page.
Base page image painting is going on. At same time popup page image is not loading up to base page paint complete. I changed popup image download to some other server means working fine.
Here my problem is same domain more than 2 request web server (iis) not responding up to first 2 requests complete. We can call 2 requests at a time. How to increase more than 2 request in ie. This problem is not available in Firefox. Firefox can manage more than 2 requests. Ie not allows only 2 requests to one domain at a time.
How to send more than 2 requests from ie to a domain?
I want to make sure my theory of an upcoming project will work. Online ordering form for a restuarant. Order will be for pickup or delivery. no payment online. so gather order information and call web service which lives on a computer at the restaurant, this web service will log the order information into a file then send the order information to a ticket printer in the kitchen.
I"ve stepped through the code and it would appear that there's another postback somewhere on my MasterPage, the Popup is on my Child page, therefore it gets killed.
What i'm trying to do is on my default on_load, check for a cookie and if there isn't one, display a Popup. It seems that the child page renders before the Master???
Anyhow, I don't really want to put the code for the Popup in the Master after the rest of the controls have loaded since its only needed on the one page.
*edit* I added a button and the on_click does the exact same thing it pops up and disappears, I cannot step through the Modal process
What's the simplest and most effective way to selectively redirect HTTP requests to your ASP.NET page to its HTTPS equivalent? For example, if my page site URL is [URL], I want to redirect some (or all) page requests to [URL] What's the easiest way to do that?
I m facing problem updating a method which shows the count on master page. That method is bind to treeview control.Whenever a data is saved count is incremented to one. but method gets refreshed only when there is a postback. I want it to be updated after every few seconds or whenver there is data saved. there is pretty gud solution with custom ajax that is with json. But that is not possible with exiting solution.i have to redesign the complete treeview structure in html. And with timer control of ajax whole page gets refreshed.
There are many customer' order as pdf file stored in one file server.my app just open url (file path) to display pdf file on the screen.Now, boss want me to create a asp.net app to send an email with attached order pdf file which is the same url as intranet. How to complete it?
i use 'create user wizard' for send confirmation code to an email id..but before sending a 'confirm code' on given emailid.. i want check that setting of smtp server in system.net in webconfig are ok and able to send mail..otherwise alert a message "smtp setting is enable to sending mail"
i find a lot of websites that have some parts in the page that uses ajax much more faster than i used to see ajax requests
like changing views using tabs when i click a tab it changes content very fast than i used to in my web applications using Asp.Net and Ajax Control Toolkit
and also a very quick paging in repeaters or grids than i ever developed in my web apps
like this website [URL] i need to know which technology used to achieve this this website is developed using .net
so
but i need to know is this needs another technology to learn (from where can i learn it)
or is it just asp.net + ajax or whth other technology
is it MVC
also i want to know if MVC is better than asp.net + ajax in concern with performance
This is sort of a continuation of a previous thread: View thread
The requirement I have is to be able to have a popup form that shows detailed data on a facility. This would be available on various pages of the website where the user may want to drill down and see detailed information on a facility. We also want to allow the user to update the data on the facility if so desired. I have the code working to show the popup form and get the html for the popup from a view. Right now I'm setting the values of the input boxes using razor code that accesses the @model object. That's about as far as I've gotten.
Where I'm struggling is:
1. How to tie the data in the inputs back to the view model. 2. How to write the ajax code to write the data back to the server. I tried using a standard form, but that redirects the original page that popped up the form. I want to leave that page alone and just submit the data back to the server and close the popup.
Now my dev lead wants us to use the dojo toolkit for our javascript library. That would be OK if I already knew what I was doing with regard to web development, but I don't - and documentation is just not very good with regard to dojo. I'm still trying to figure out html and mvc, so I thought I'd see if I can get this scheme working with some other javascript library first, and then see about switching it over to dojo.
I've read some about knockout and jquery, but with everything being so new to me it's hard to get all this to gel in my head, and I'm not sure about my design. I've read some about mvc's built in ajax tools, but so far all I'm seeing is stuff related to getting data and displaying it - not about submitting data.
I'd like to be able to send the data back to the server in the same object structure that I extracted it with - something that matches the model. I think this is doable, but I'm not sure - and the 'how' of it is escaping me at this point.
I have a few updatepanel in my asp.net webform . I'm doing some tests and I'm wondering how can i check what data send back to server in different situations ?
How do you handle ajax requests when user is not authenticated?
Someone enters the page, leaves room for an hour, returns, adds comment on the page that goes throuh ajax using jQuery ($.post). Since he is not authenticated, method return RedirectToRoute result (redirects to login page). What do you do with it? How do you handle it on client side and how do you handle it in controller?

I have many Ajax.ActionLink's on my ASP.NET MVC (v1) page that perform destructive operations. This is "legal" because I set HttpMethod to DELETE in this case so it's not a destructive GET.
My question though is how to mitigate XSRF attacks on this operation so that other sites cannot craft this same Ajax DELETE request to delete user data from another site. This ActionLink does appear within a form that includes <%= Html.AntiForgeryToken() %> but since ActionLinks don't post the form, the anti-forgery token doesn't go to the controller, so it can't validate it.
i'm just sending a normal POST request using Ajax.BeginForm... i output the form elements using the .TextBoxFor and .HiddenFor etc... all as i should... and when it's posted via ajax to my action method, the object in the action method (named "Comment") is not populated with the values!
Am i missing something? here is the relevant part of my code to those who want to see it...
In my ASP.NET MVC2 web app I have a page which goes off and gets results from a number of different web service feeds. These return times vary so I want to basically display them as they return after the page loads. I also want my user to be able to kick of requests that can run concurrently with these other requests.
At the minute my page just seems to queue up the requests. The web service calls returning one at a time in the order they are called and then the user can kick of requests.
Is this a case for the asyncController or is there an easier/better way of working this?
A customer wants us to create an ajax-enabled web application that can be used to manage their IT environment (Active directory, mail, file security, ...). However, as the team that will support the web application does not know anything about these IT systems, they would like to split the coding so that all interfacing with the IT environment is done via PowerShell, which is known by the administrators of these systems. This would mean that if new functionality is required, the web team can just create an additional web page and interface and use PowerShell scripts that get created by technically skilled people in that specific topic (ie mail administrators). I don't see an issue using this approach for requests like adding a user where latency is not an issue, but I do wonder if this is feasible for interactive content with Ajax.
Ie I would like to implement a google suggest like search for AD users. This would mean that ie for every x keystrokes (or x seconds whatever approach I implement) an Ajax request will be made and the web application or web service will than use PowerShell to get the data. Taken into account that up to about 75 users can use this feature, is this something that would work? Not only performace-wise but also the number of connections (I read about the Powershell 5 remote session limit but also that it could be put to a higher number)? The example above is probably the most resource heavy Ajax requests (and can be optimized by caching), so taken into account they don't want this nice feature, are basic PowerShell scripts in ajax request really an option. My gut feeling is telling me this is a no-go, but I don't want to exclude the option just because it's not something I usually would do.
I'm am experiencing some strange behavior with a website. I have a page that performs a simple AJAX request to fill a div. The data is fetched from a page in the same domain. When I perform the request using [URL]. The requests work perfectly, but when using [URL] or [URL]. My requests are simply ignored. I've used Firebug to track requests, and not even a single ajax request is performed. Normal requests (such as fetching the main page that invokes the ajax code) works fine on both scenarios.
I'm creating a page that makes multiple AJAX form posts without a page refresh.
I would like to use the ASP.NET MVC HTML.AntiForgeryToken() helper to secure the form against CSRF attacks. I think that each form on the page can share the same token, but will it allow multiple requests with the same token? If not is there a way to get a new token or some other way to secure the forms?
i'm trying to intercept ajax requests with jquery, to display a waiting message like with using plugin BlockUI, but how can i intercept requests sended by the UpdatePanel provided from asp.net framework, is some way to take the trigger?
I have 5 hard corded texboxes in a page in a sequence with sequence Number . Now i want to add re-order /re-arraning functionaly .. but i can't use ajax reorder list because i have 5 hard corded texbox. how can i maintain the order in Insert/Update cases. And also suggest me control that i can use, another than ajax re-order list. coz i not using any list items i have hard corded items on the page.
The AjaxToolkit has a ReorderList. I'm searching for a jQuery solution that does the same and found this page. I would like to change the order of divs (vertically) and upload the new order to the database (ajax).
