I need to get notified about asynchronous requests in ASP.NET. I used the jQuery .ajaxSend global event but it does not trigger when using UpdatePanels.
Is there a multi-browser way to detect when a request is being made on a page?
I have a question about the blockUI plugin.There are only three controls in my aspx page. Two buttons and one label.There is one button and one label sitting inside a hidden Div. The second button is outside the div.
When I click on the button outside, the modal popup will show (means the hidden div shows)My purpose is to let the label control to display some text when I click on both buttons. Sounds very simple, right? But with blockUI, it seems very difficult to me.The problem is, when I click either button, the label control doesn't display anything. It seems that BlockUI fires before the postback.
Here is my code

I have installed an HttpModule into my web app that will handle all requests with a given file extension.
I want ASP.NET to handle all requests with the extension, regardless of whether there is an underlying file on disk. So, when I added the extension to the 'Application Extension Mappings', I unchecked the 'Verify that file exists' checkbox.
However, this just transfers the file check to ASP.NET rather IIS, so I just get a different error page when requesting URLs with the file extension.
Is there a way to preempt this ASP.NET file checking and intercept the requests?
I have developed a payment processing form where user fills the payment details and submit the button "Pay Now" ..what i want is to block the entire UI with the message "Processing Payment..." and with a slight delay right after payment processing stored procedure executes (in code behind) it should UNBLOCK the UI. Actually i was having multiple postbacks from user due to the slight delay ...I dont want to disable button.
View 1 RepliesTrying to use BlockUI and asp.net validation groups on a page but the validators are not fired.How to check which control fired the event and fire the validation group of that event inside jquery ?Here is the script file.

I am using BlockUI to show a modal. Within the blocked modal I have an update panel. Within the update panel I have a textbox and a button that submits the content back to the server. Everything works fine up to this point (the blockUI is called, the modal appears, and the button performs the postback). However, when the button's click event is fired the value for the textbox is consistently empty even if text was entered. When the update panel updates the textbox shows up blank. It appears that this may be some sort of viewstate issue and I haven't turned off viewstate.

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]
so i need to know which technology used to achieve this this website is developed using .net
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
I want to show a Jquery blockUI when I click an asp:button that triggers a serverside function.
When the function ends, I want to do the unBlockUI.
While using blockUI function of Jquery I am getting below Error:
parentNode is Null Or not an object I am display a div using the below code
$.blockUI({message:$('#divID')});
First time it will execute nicely but second time it gives error.
When I was reading the blog Using jQuery to Consume ASP.NET JSON Web Services
I have seen this argument:
"By using jQuery to call the web service directly, we've eliminated over 100 KB of JavaScript and three extra HTTP requests. "
Why does the ASP.NET AJAX call to a .NET Web-Service needs 3 extra HTTP requests? What are those requests? (I wonder how jQuery manages the call with lesser HTTP requests in this case).
Yesterday I upgraded to MVC 2 RC. I have several jquery ajax requests that worked fine prior to the upgrade. Sometimes they work, sometimes they don't.
I know the MVC team made changes to the framework to protect against Json Hijacking so that GET requests are not allowed (by default) and I have changed my jquery ajax code to use 'type: "POST",' and then adorned the Action Method with the POST verb.
Again, the odd thing about this is that it works sometimes and other times it doesn't. When it fails, there are no error details. The error code is 12030 or 12031.
I'm using jQuery BlockUI Plugin to show busy message when a click event is fired.
In the scenario below, it's working fine. The busy message shows and locks UI on click event, and dissapears when postback's done.
No file creation involved, which invokes browser Open/Save As dialog box
Mark-up:
$(function() { // when document has loaded
($.unblockUI); //unlock UI
//Show busy message on click event and disable UI
$('#btnDemo').click(function() {
[Code]....
I want to get rid of the busy message and unlock the UI when Open/Save As dialog box appears.
I have a username textbox on a form, that has a few validation rules applied to it via the DataAnnotation attributes:
[Required(ErrorMessage = "FTP login is required")]
[StringLength(15, ErrorMessage = "Must be 15 characters or fewer")]
[RegularExpression(@"[a-zA-Z0-9]*", ErrorMessage = "Alpha-numeric characters only")]
public string FtpLogin { get; set; }
I also have a button next to this text box, that fires off a jQuery ajax request that checks for the existence of the username as follows:
<button onclick="check(this);return false;" id="FtpLoginCheck" name="FtpLoginCheck">Available?</button>
I'm looking for a way of tieing the two together, so that the client-side validation is performed before the call to the "check(this)" in the onclick event.
Edit: To be more clear, I need a way to inspect or trigger the client-side validation result of the textbox, when I click the unrelated button beside it.
Edit: I now have the button JS checking for $("form").validate().invalid, but not displaying the usual validation messages.
This is a followup question to the one here
Here's briefly what I am trying to do. The File server creates a text file to indicate an end of the process. On a webpage on the Web Server, I loop every x seconds and make an ajax request to find out if the test file exists (ajax request to [URL]
I've tried the following approaches so far:
Trigger a web method from the client side that creates a HttpContext object to verify if the text file exists. But this is too strenous on the server and I started getting all kinds of exceptions in the Event Viewer.
I added a new asmx file, which start like this:
[Code]....
I have uncommented the ScriptService line to allow access from scripts.
What else do I need to set to make jquery connections?
Can I prevent access from outside my app? I only want to provide a service for signed-in users (web forms) via own webpage.
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?

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'm trying to call an blockUI after a buttonclick, but I can't get it to work.What am I doing wrong?Script:

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.
