How can I prevent page reloading when submitting form in partial view? There are a lot of examples but it seems that non of them is working for me. This is what I have. Partial view (Razor) which calls this:
#using (Ajax.BeginForm("SaveReply", "Home", null, new AjaxOptions { HttpMethod = "Post" }, new { target = "_self" }))
{
<div class="input-group wall-comment-reply" style="width:100%">
#Html.Hidden("eventid", #item.EventID)
<input name="txtReply" type="text" class="form-control" placeholder="Type your message here...">
<span class="input-group-btn">
<button class="btn btn-primary" id="btn-chat" type="submit">
<i class="fa fa-reply"></i> Reply
</button>
</span>
</div>
}
Then I have my action method in the controller:
[HttpPost]
public void SaveReply(string txtReply, string eventid)
{
//some code
}
The controller action is fired but after that it is automatically redirected to localhost/home/SaveReply
Maybe the problem is that this partial view is rendered from string. I took the code from:
How to render a Razor View to a string in ASP.NET MVC 3?
Also amongs other things i tried this:
http://geekswithblogs.net/blachniet/archive/2011/08/03/walkthrough-updating-partial-views-with-unobtrusive-ajax-in-mvc-3.aspx
I would appreciate any help.
I found the problem.
It seems that you need to reference the Unobtrusive scripts. Just install them from NuGet:
Install-Package Microsoft.jQuery.Unobtrusive.Ajax
And then reference it from the View that calls the Partial View:
<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>
And miraculosly it works without any other changes. More explanations can be found here:
[Why does Ajax.BeginForm replace my whole page?
and here:
[Why UnobtrusiveJavaScriptEnabled = true disable my ajax to work?
It seems that you need to use it if you are using Ajax.* helpers in MVC 3 and higher.

I am doing an MVC tutorial and have hit a problem.
I changed a working view from using Html.BeginForm to Ajax.BeginForm. But the form is not submitting.
Per my research I verified that ClientValidationEnabled and UnobtrusiveJavaScriptEnabled are both set to true in web.config. I do have the most recent version of jquery.unobtrusive-ajax,js and jquery refrenced. But still no joy.
I firebugged jquery.unobtrusive-ajax to see what it was doing. It is setting itself up on page load. But no functions are called when I click the submit button.
Here is a snippet from View Source to show how the form tag is begin set up:
<div id="formSection">
<h3>Having trouble? Send me a message</h3>
<form action="/Home/Contact" data-ajax="true" data-ajax-method="post" data-ajax-mode="replace" data-ajax-update="#formSection" id="form0" method="post">
</form>
<textarea name="message"></textarea>
<input type="submit" value="send" />
</div>
My error became apparent while asking the question. I was cleaning up the bad formatting of the HTML when I saw the end form tag was before the submit button!
I had an error in my Razor code.
#Using (Ajax.BeginForm("Contact", "Home", New AjaxOptions With {.HttpMethod = "post", .InsertionMode = InsertionMode.Replace, .UpdateTargetId = "formSection"}))
End Using
<textarea name="message"></textarea>
<input type="submit" value="send" />
Putting the End Using right after the Using closed the block of course, so the input element never got into the form.
Correct syntax:
#Using (Ajax.BeginForm("Contact", "Home", New AjaxOptions With {.HttpMethod = "post", .InsertionMode = InsertionMode.Replace, .UpdateTargetId = "formSection"}))
#<textarea name="message"></textarea>
#<input type="submit" value="send" />
End Using
It would have been nice if the generated code was formatted well, I would have seen the end form tag location much sooner.
Hopefully I help avoid a few head slaps.
I want to show some flash message after completion of AJAX call. I am doing like this ..
Controller Action --
def subscribe()
{
def subscribe = new Subscriber()
subscribe.email = params.subscribe
if (subscribe.save())
{
flash.message = "Thanks for your subscribtion"
}
}
View Part --
Subscribe :
<g:formRemote onSuccess="document.getElementById('subscribeField').value='';" url="[controller: 'TekEvent', action: 'subscribe']" update="confirm" name="updateForm">
<g:textField name="subscribe" placeholder="Enter your Email" id="subscribeField" />
<g:submitButton name="Submit" />
</g:formRemote >
<div id="confirm">
<g:if test="${flash.message}">
<div class="message" style="display: block">${flash.message}</div>
</g:if>
</div>
My AJAX working fine but it is not showing me flash.message. After refresh page it displaying message. How to solve it ?
When you use ajax your page content isn't re-parsed, so your code:
<g:if test="${flash.message}">
<div class="message" style="display: block">${flash.message}</div>
</g:if>
will not run again.
So I agree with #James comment, flash is not the better option to you.
If you need to update your view, go with JSON. Grails already have a converter that can be used to this:
if (subscribe.save()) {
render ([message: "Thanks for your subscribtion"] as JSON)
}
And your view:
<g:formRemote onSuccess="update(data)" url="[controller: 'TekEvent', action: 'subscribe']" name="updateForm">
<g:textField name="subscribe" placeholder="Enter your Email" id="subscribeField" />
<g:submitButton name="Submit" />
</g:formRemote >
<script type='text/javascript'>
function update(data) {
$('#subscribeField').val('');
$('#confirm').html(data.message);
}
</script>
You have couple options,
First you can try to return the message from your controller in a form of json or a map and render it on the screen your self using javascript libraries, which is a bit different if you want to use Grails ajax tags.
The other option is using a plugin like one-time-data , which
Summary A safe replacement for "flash" scope where you stash data in
the session which can only be read once, but at any point in the
future of the session provided you have the "id" required.
Description
This plugin provides a multi-window safe alternative to flash scope
that makes it possible to defer accessing the data until any future
request (so long as the session is preserved).

Hi there I have an error when I submit the following form:
<div id="tabs">
<ul>
<li>Project Details</li>
<li>Project Attachments</li>
<li><a href="#Url.Action("Members", "ProjectNetwork", new { IsTab = true })">Project
Network</a></li>
<li>Bulleting Board</li>
<li>Bids Received</li>
</ul>
</div>
<div id="LowerButton">
#Html.Hidden("MainStatus", #Model.Status)
#using (#Html.BeginForm("Dashboard", "Dashboard"))
{
<button type="button" id="MakeComment">
Make a Comment
</button>
<input type="submit" id="GoDashBoard" value="Return to Project List" />
}
</div>
When I press the button "GoDashBoard", The method "Dashboard" in the controller "Dashboard" is not reached. Instead the following error appears:
It tells me that a model property is beign sent to the server. However, there are no model properties inside the dashboard form.. unless I'm sending many forms at the same time. But I dont think thats possible right? Do you guys have any idea of why is trying to set a model property when I'm not actually sending any?
Update:
this is the input of the dashboard action:
public ActionResult Dashboard(int page = 1)
{
var user = (User)Session["User"];
if (user != null)
{...
}}
the input is a default integer. However, I saw the trace of the calls and its submiting another form which is not related to the one im using:
That form is inside of one of the ajax tabs. I dont understand how one form submits another form and they are not nested. Anyone knows a good workaround? because im thinking of receiving both forms in both actions and make some validations.
I solved it by removing the form "Dashboard" and instead adding an invisible link. The button would reference the invisible link:
#*#using (#Html.BeginForm("Dashboard", "Dashboard"))
{ *#
<button type="button" id="MakeComment">
Make a Comment
</button>
<button name="button" type="button" onclick="document.location.href=$('#GoDashBoard').attr('href')">Return to Project List</button>
<a id="GoDashBoard" href="#Url.Action("Dashboard", "Dashboard")" style="display:none;"></a>
#*<input type="submit" id="GoDashBoard" value="Return to Project List" />*#
#* }*#
I have the form and some code below.
#using (Html.BeginForm("Insert", "Question", "POST"))
{
<div id="add_tag">
<div id="list_tag">
<span class="post-tag" id="2">Phi kim<span class="delete-tag" title="Xóa Tag này"></span></span>
<span class="post-tag" id="22">Hóa Vô Cơ<span class="delete-tag" title="Xóa Tag này"></span></span>
<span class="post-tag" id="1">Lý<span class="delete-tag" title="Xóa Tag này"></span></span>
</div>
<div class="tag-suggestions hidden">
</div>
</div>
<div class="form-sumit clear">
<input type="submit" id="submit-button" value="Post your question" />
</div>
}
And my Insert action in QuestionController like this
[HttpPost]
[ValidateInput(false)]
public ActionResult Insert(FormCollection _form)
{
//my code here
}
I want to get id of span tag nested in by using Html.BeginForm and FormCollection. How can I do that? Plz someone help me. Thanks a lot.
When you click on submit button, form collects all input values inside this form and send to the server with the following format: inputId=inputValue. Span isn't the input control inside the form and form does not collect its value or another information to send to the server. You can generate hidden input control and set the id value to it. And then at the server side in the action you can get it from FormCollection.
[HttpPost]
[ValidateInput(false)]
public ActionResult Insert(FormCollection formCollection)
{
//for example all hidden input controls start with "hidden_tag" id
//and end with your number of tag:
var allNeededKeys = formCollection.AllKeys.Where(x => x.StartsWith("hidden_tag"));
var listOfId = allNeededKeys.Select(formCollection.Get).ToList();
}
Good luck.
I'm pretty sure you can't. You can use fiddler to see if they're posted back to the server but I don't think they are.
You should use hidden fields to post the span's id to the server.
Is the view strongly typed?
I'm experiencing a strange problem while trying to use the Ajax.BeginForm method of ASP.NET MVC3. The form renders properly on the page with the correct action attribute. However, when the form is submitted, the "OnFailure" event is returning a "Not Found" 404 error.
If I watch the request with fiddler, I see that the post URL is "/[Object NodeList]" which is obviously invalid.
My Razor code is as follows:
#using (Ajax.BeginForm("Save", "Items", new AjaxOptions { UpdateTargetId = "itemContainer", InsertionMode = InsertionMode.Replace, OnFailure = "onFailure"}))
{
<div style="position:absolute; bottom:20px; left:200px;">
<button type="submit" id="Save" name="action" value="Save">Save</button>
<button type="submit" id="Cancel" name="action" value="Cancel">Cancel</button>
</div>
}
The problem was using "action" for the name attribute on the submit buttons. As soon as I changed the name attribute to a different value, everything started working perfectly.
I'm guessing that there is a jQuery selector in the unobtrusive ajax library that got confused.
Do you have unobtrusive JavaScript on or off in your web.config? Im first guessing here the ms Ajax library is acting goofy so enable unobtrusive so we get jquery support.
What is your form action set to? Post your form HTML element if you can .
