Does anyone know what I need to get the ajax.beginform to work in my MVC4 project? I updated the jQuery library to version 2 and I have included the jquery.validate.js and jquery.validate.unobtrusive.js but the form is still posting to the new page rather than just updating the UpdateTargetId element
I have had a google and a lot of people seem to be having problems with a script called Microsoft.jQuery.Unobtrusive.Ajax but this isn't in my project. Do I need to install this, and if so do I then need to do a find and replace on live so that it uses on instead?
This is the form code:
#using (Ajax.BeginForm("AddImage", "Quote", FormMethod.Post, new AjaxOptions { UpdateTargetId = "Files" }, new { enctype = "multipart/form-data" }))
{
}
This posts to the quote controller addimage action and all that does is write out a string to the screen (which should appear in the Files div) but instead of doing an ajax call it is actually going to the Quote/AddImage page
All I had to do in the end was download the latest jquery.unobtrusive-ajax.js through nuget. This has been updated so it works with jquery 2
First, you're missing InsertionMode in your AjaxOptions.
Second, it seems you're trying to upload files using Ajax form? You won't be able to. Please see this post, for example.
Finally, Ajax.BeginForm is using jQuery.live() function, which has been removed as of jQuery version 1.9. See this question for more info.
You should install jQuery Migrate Plugin which will restore deprecated features. This will at least restore your Ajax form functionality. Alas, it won't help you upload files through Ajax. But that's a different topic.
I am new to web development..
i have created views using Entity Framework in MVC3 Razor..
What i have done yet is,
i 1st created model(Clients) and DbContext(ClientDbContext) Classes.
then, i add controller with scaffolfind options
Template: Controller with read/Write actions and View, Using Entity Framework
Model Class: Clients
Data Context Class : ClientDbContext
Views : Razor(CSHTML)
It Creates the controller class and index, Detail, Delete, Delete Views...

But i need to popup those views when i click the links in the index page...
i don't know how to do this... i studied many articles but i am confused...
Please help me to solve this with an efficient manner...
Thanks in advance...
Creating a model pop-up within a page isn't something that can be done directly with ASP.NET MVC. You could do it yourself using javascript & css but I would strongly recommend using a JS UI framework to do this. jQuery UI has a pop-up modal box, except they call it a dialog.
The docs for jQuery UI's dialog can be found here. Have a look through the examples to see the fine details of how to set it up. But this is the basic flow of what you need to do:
Download the jQuery UI files needed and include them on your page (CSS/JS files)
Take the html from your create/update/delete views and put it on your index page, wrap them in a div with an appropriate id
When the page loads use jquery ui to target your div's you want to be a popup
Things such as the link you want to make a dialog popup is set by passing options to the dialog initialize method, again the exact options and examples can be found on the docs page.
Refer this : http://jqueryui.com/dialog/ to create a jQuery Dialog box.
<script>
$(function() {
$( "#dialog" ).dialog();
});
</script>
<div id="dialog">
#using(Html.BeginForm()){
#Html.EditorForModel()
<input type='submit' value ='Submit'/>
}
</div>
I'm trying to learn more about asp.net ajax. But when I followed (this short tutorial, the functionalities are not working like they supposed to be. If you click on the actionlink, an ajax call should be executed and return a string on the same page. In my project he renders a new page and returns a string. I follow the tutorial 2 times and could not find my problem. Many Thanks if anyone can help
rendering code html when the page opens
<p> Page Rendered: 15:00:09 </p>
<span id="status">No Status</span>
<br>
Update Status
code html when i click the link (this is in a new page)
<body>Status OK at 15:04:12</body>
you can find the program code in the link from the tutorial, because I copy pasted it.
Only thing that changes is the view engine (razor)
i wouldn't even mess with the MSFT ajax stuff. jquery is the industry standard but there are other javascript libraries such as Moo and YUI. i can't imagine what benefits the msft library would have over these other ones.
After upgrading my ASP MVC from 3 Preview to 3 Beta I see strange behaviour in my Ajax forms.
#using(Ajax.BeginForm("New", new AjaxOptions() {OnSuccess = "onAjaxSuccess", OnFailure = "onAjaxFailure", OnBegin = "onAjaxBegin", HttpMethod = "Post"})) {}
<form action="/Order/New" data-ajax="true" data-ajax-begin="onAjaxBegin" data-ajax-failure="onAjaxFailure" data-ajax-method="Post" data-ajax-success="onAjaxSuccess" method="post"></form>
I have placed an alert inside my function onAjaxBegin and it is beeing fired twice, each time i click on my submit button.
Anyone else seen this behaviour? I have not changed anything in the code after upgrading, and it worked perfectly before the upgrade.
I had the same problem, and i found the solution: I included the "jquery.unobtrusive-ajax.min.js"-Script twice :-)
Look at the generated HTML. In ASP.NET MVC 3 Beta there's new support for unobtrusive jquery based ajax and all the Ajax helpers use jquery now. Maybe there's something left with MS Ajax which causes the double call. Make sure you remove all the inclusions of MSAjax scripts from the page. Also why using Ajax.BeginForm when you could simply use Html.BeginForm with unobtrusive jquery?
The duplicated jquery.unobtrusive-ajax.min.js can also happened if your controller returns a View() instead of PartialView().
I had the same problem using a AJAX.BeginForm call that is loaded dynamically using $.load()
I solved it by removing the extra include of jquery.unobtrusive-ajax.min.js on the loaded form. That's the key!
one small tip all the time before you using .live(), do .die() :)
this will kill all the java scripts attached to this event and will create a new one.
example:
$(function() {
$('#MyInfoForm').die();
$("#MyInfoForm").live('submit', function(e) {
//some code
e.preventDefault();
});
});
Just for future reference for those using ASP.NET MVC; "~/Scripts/jquery.unobtrusive*" does also include "~/Scripts/jquery.unobtrusive-ajax.js".
So if your BundleConfig looks like this;
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js",
"~/Scripts/jquery.unobtrusive-ajax.js"));
bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
"~/Scripts/jquery.unobtrusive*",
"~/Scripts/jquery.validate*"));
It will result in submitting an Ajax form twice. Removing either "~/Scripts/jquery.unobtrusive*" or "~/Scripts/jquery.unobtrusive-ajax.js" will fix the problem.
Just posting this because it is easy to overlook "~/Scripts/jquery.unobtrusive*" when searching for unobtrusive-ajax.
You can use bind instead of live in jquery.unobtrusive-ajax.min.js~~~ This is very important.Because live event will call the previous events every time but bind only calls the current event.
Moving jquery.unobtrusive-ajax.js outside partial-view solved the issue in my case.
I had the same problem. I had a login partial view in master page that included jquery.unobtrusive-ajax.min.js. I also had this file included in my view. So I removed one and the problem is solved now.
I also had this exact problem and for a very different reason. I had included the script reference to the jquery.unobtrusive-ajax.min.js within the div that got updated. Moving it outside the div fixed it.
This might be helpful for someone having a scenario similar to what I have:
On my page, the edit form opens a partial view inside a Kendo UI modal pop-up window, which loads the code of the form dynamically, including jquery.unobtrusive-ajax.js. With this setting, - which can relate to any pop-up such as that of jQuery UI and not just Kendo UI - the behavior of form submission is as follows:
The first time the pop-up window is opened, the form submission causes a single call to the controller (server-side) code. So far so good. However, for the second time that the window is opened (without closing the container page), the form submission calls the controller 2 times. Subsequently, each re-opening of the pop-up window, causes an additional loading of the jquery.unobtrusive-ajax.js code, which in turn causes an additional unwanted call to the controller at each single submission of the form.
In order to fix the problem, I moved the inclusion of jquery.unobtrusive-ajax.js from the partial view of the pop-up window into the main page. However this made the client-side validation stop working, and to fix that, I used the solution provided in here:
client side validation with dynamically added field which links to this blog post:
http://xhalent.wordpress.com/2011/01/24/applying-unobtrusive-validation-to-dynamic-content/
I found out the solution, just remove all jquery.unobtrusive-ajax.js references, since you are using the Ajax.BeginForm it will use the ajax normally.
So it doesn't has to disable the ajax.
this is old but I found something really stupid that is easy to overlook.
Our form also had the following attached to it:
$(document).ready(function () {
$('#submit-button').on('click', function (e) {
....
}
});
Obviously the .NET code handles this itself.
I am looking to implement a live search in my MVC app similar to this site when you type in a question and results come up that are similar or like the search on http://www.krop.com/
I have the search code all working and results updated. I just need to know how to add the AJAX to the MVC framework (I know this site was built using it) so that when I type the results are updated.
I had this all working in normal ASP.NET Forms app.
what you need to do it attach to Jquery onchage event handler, and then call some ajax method of jquery ($.load , $.ajax etc...) and the information from a specified controller. asp.net mvc controller can return json results so you can later manipulate it in your javascript code.
if you have any other questions go ahead and ask.
An ASP.NET MVC site will have AJAX and JQuery available by default.
Mike Bosch's Blog can give you some pointers on this
