simplest way to post post data from mvc dialog to controller? - model-view-controller

How can I send data from a dialog to the controller? Model Binding?
Can I have example please?

I'm making some assumptions here based on your previous questions that you are interested in ASP.NET MVC and are using jQuery UI dialogs. Further I'm guessing that you want the data submitted without reloading the page -- i.e., the dialog should be dismissed and return you back to the original page.
The simplest way is to create a form in the dialog and have that form submited via AJAX. I would suggest that you have the dialog populated via a controller action that loads a partial view. This will make it simpler to generate the mark up for the dialog. Give the content area of the dialog a class that makes it easy to find once the dialog is created, then in the dialog open handler replace the HTML inside the content area via a load to the controller action. Use the buttons on the dialog to submit the form.
$(function() {
$('.someSelector').click( function() {
$('<div title="Update Contacts"><p class="dialog-content"></p></div>').dialog({
autoOpen: true,
modal: true,
open: function() {
$(this).find('.dialog-content')
.load( '<%= Url.Action( "show", "contact", new { id = Model.UserID } ) %>',
function() {
$(this).find('form').submit( function() {
return false;
}
}
);
}
buttons: function() {
'Update': function() {
var $this = $(this);
var form = $this.find('form');
$.post( form.attr('action'), form.serialize(), function(){
$this.dialog('destroy');
});
},
'Cancel': function() {
$(this).dialog('destroy');
}
}
});
});
});
Partial view
<% using (Html.BeginForm( "update", "contact", null, FormMethod.Post, new { id = "contact-form" } )) { %>
<%= Html.EditorForModel() %>
<% } %>

Asp.net core controller function with return partial view with select2 not working and remote function validation is not firing in modal popup

Select2 is not working and remote validation is not firing, this is only happens when I convert the code to modal popup but if not everything is working properly. What Am I missing in my code? Any advise or help much appreciated.. Thank you
Here is my code the modal:
$('#tbProducts tbody').on('click', 'button', function () {
var data = productsTable.row($(this).parents('tr')).data();
//alert(data.id);
$.ajax({
url: '#Url.Action("Edit", "Products")',
type: 'GET',
data: { id: data.id },
success: function (result) {
$('#EditUnitModal .modal-content').html(result);
$('#EditUnitModal').modal()
}
});
});
Here is the controller edit code:
public async Task<IActionResult> Edit(int? id)
{
//code here
return PartialView("__Edit", product);
}
And here is my partial view __Edit code:
#model intPOS.Models.Master.ViewModel.ProductViewModel
//code here
#section Scripts {
#{await Html.RenderPartialAsync("_ValidationScriptsPartial");}
<script type="text/javascript">
$(function () {
$('#Unit').select2({
theme: 'bootstrap4',
dropdownParent: $('#EditUnitModal')
})
$('#Category').select2({
theme: 'bootstrap4',
dropdownParent: $('#EditUnitModal')
})
})
</script>
}
And View model code:
[Display(Name = "Product Code"), Required]
[Remote("CheckProduct", "Products", AdditionalFields = "Id", ErrorMessage = "Product already exists.")]
public string ProductCode
{
get
{
return _productcode;
}
set
{
_productcode = value.Trim();
}
}
Sample screen for not firing validation and select2 is not working:
sections aren't allowed in partial views. You can still use modals and partial views via Ajax for edit forms but there is a small modification you need to do in order for this to work:
Include all the necessary scripts in your page (this is mandatory as sections aren't allowed in partial views).
In your javascript code add these lines in order to parse the new form via jquery validation unobtrusive and your select elements via Select2.
$('#tbProducts tbody').on('click', 'button', function () {
var data = productsTable.row($(this).parents('tr')).data();
//alert(data.id);
$.ajax({
url: '#Url.Action("Edit", "Products")',
type: 'GET',
data: { id: data.id },
success: function (result) {
$('#EditUnitModal .modal-content').html(result);
//Here we parse the new form via jquery validation unobtrusive.
$.validator.unobtrusive.parse($('#EditUnitModal .modal-content form')[0]);
//Here we initialize select2 for the selected elements.
$(".yourSelect2ElementClass").select2({//options...});
//Now we launch the modal.
$('#EditUnitModal').modal()
}
});
});
Don't forget to remove the section from your partial view and include your scripts in the containing view.

Unable to serialize a form that contains a tinymce editor for an Ajax call

I'm trying to post a form that contains an instance of tinyMCE editor to an action method using AJAX. My View:
<script src="#Url.Content("~/Scripts/tinymce/tiny_mce.js")" type="text/javascript"></script>
<div>
<fieldset>
#using (Html.BeginForm("SubmitNewTRForm", "LaboratoriesOrdersGrid", FormMethod.Post,
new {enctype = "multipart/form-data", #id = "newTrUploadForm" }))
{
<div style="overflow: hidden;width: 763px; height:312px; border: black solid thin;">
#Html.TextAreaFor(model => model.TestSummary, new {#class="TestSummaryEditor"})
</div>
}
</fieldset>
</div>
In the same view I instantiate the editor:
$(document).ready(function () {
tinyMCE.init({
directionality: "rtl",
width: "760",
height: "300",
language: 'fa',
// General options
mode: "textareas",
theme: "advanced",
plugins: "autolink,lists,pagebreak,style,layer,table,save,advhr,advimage,advlink,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template",
// Theme options

theme_advanced_buttons2: "cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,anchor,cleanup,|,insertdate,inserttime,preview,|,forecolor,backcolor,|,insertlayer,moveforward,movebackward,absolute,|,blockquote,pagebreak,|,insertfile,insertimage,|,visualchars,nonbreaking,template",
theme_advanced_buttons3: "tablecontrols,|,hr,removeformat,visualaid,|,ltr,rtl,|,cite,abbr,acronym,del,ins,attribs",
theme_advanced_toolbar_location: "top",
theme_advanced_toolbar_align: "left",
theme_advanced_statusbar_location: "bottom",
theme_advanced_resizing: true,
// Skin options
skin: "o2k7",
skin_variant: "silver",
add_form_submit_trigger: false,
// Example content CSS (should be your site CSS)
content_css: "css/example.css",
// Drop lists for link/image/media/template dialogs
template_external_list_url: "js/template_list.js",
external_link_list_url: "js/link_list.js",
external_image_list_url: "js/image_list.js",
media_external_list_url: "js/media_list.js",
// Replace values for the template plugin
template_replace_values: {
username: "Some User",
staffid: "991234"
}
});
});
ANd my AJAX call:
$("form").live('submit', function (e) {
tinyMCE.triggerSave(true, true);
e.preventDefault();
var form = $("#newTrUploadForm");
if (form.valid()) {
$.ajax({
url: '#Url.Action("SubmitNewTRForm")',
data: form.serialize(),
type: 'POST',
error: function (xhr, textStatus, exceptionThrown) {
$("#errorDIV").html(xhr.responseText);
},
success: function (data) {
if (data.success) {
}
else {
}
}
});
}
});
And my AJAX call always returns an error whenever the tinyMCE editor is on the form, removing tinyMCE solves the problem, but why is this happening? I know this issue has been addresses on SO a couple of times already but I've tried all the proposed solutions and none seem to work for me, plus those solutions are somewhat outdated. During serialization in my AJAX call, i get this error:
[MissingMethodException: No parameterless constructor defined for this object.]
Any ideas?
The error I posted and the tinyMCE problem happen to be totally unrelated. The tinyMCE problem was fixed by saving the contents after preventing the default action of the button click, basically changing my AJAX call from:
$("form").live('submit', function (e) {
tinyMCE.triggerSave(true, true);
e.preventDefault();
to:
$("form").live('submit', function (e) {
e.preventDefault();
tinyMCE.triggerSave(true, true);
and the form serialzed properly and the conents of teh editor sent to the action flawlessly.
Totally irrelevant to this question, but that error posted was caused by setting my model property's type as SelectList and the form posting a SelectListItem.
Your error indicates that the model you are trying to bind to in your controller action needs a constructor like
public yourModel
{
public yourModel()
{
//your logic here
}
}
It also doesn't look like you have a 'form' in your view to post back in the first place. I have a feeling that there are multiple errors on top of each other and the paramterless constructor is just the first one.

MVC submit form outside ajax.beginform

I have a certain ajax form and when submitted I want to include another form outside of that ajax form. Let me show you an example:
#using (Ajax.BeginForm("PayWithBankTransfer", "Payment", new { salesLineId = salesLine.SalesLineID }, new AjaxOptions
{
HttpMethod = "POST",
UpdateTargetId = "bankForm",
LoadingElementId = "spinnerBank"
}, new { id = "feedback-form" }))
{
//some stuff
<button type="submit">Reserve</button>
}
I have another tag outside of the form I want to include in the ajax form submission
<div id="theOtherStuff">
//otherStuff
</div>
How could I submit the other stuff along with the ajax form?
I don't think that MS unobtrusive AJAX supports this. So let's get rid of it and use plain jQuery. The .serialize() method is what you are looking for.
So we start by replacing the Ajax.BeginForm form with a regular Html.BeginForm
#using (Html.BeginForm(
"PayWithBankTransfer",
"Payment",
new { salesLineId = salesLine.SalesLineID },
FormMethod.Post,
new { id = "feedback-form" })
)
{
//some stuff
<button type="submit" class="t-button t-state-default" style="width: 100px; height: 50px;">Reserver</button>
}
then we provide an id to the other form so that we can reference it in our script:
<div id="theOtherStuff">
#using (Html.BeginForm(null, null, FormMethod.Post, new { id = "theOtherStuffForm" }))
{
//otherStuff
}
</div>
and all that's left is write our script in a separate javascript file to unobtrusively AJAXify this form:
$(function() {
$('#feedback-form').submit(function () {
$('#spinnerBank').show();
$.ajax({
url: this.action,
type: this.method,
data: $(this).add('#theOtherStuffForm').serialize(),
success: function (result) {
$('#bankForm').html(result);
},
complete: function () {
$('#spinnerBank').hide();
}
});
return false;
});
});
The following line should be of particular interest:
data: $(this).add('#theOtherStuffForm').serialize(),
As you can see the .serialize method allows convert multiple forms into suitable serialized form.
It is more than obvious that you should not have conflicting names with the input elements of the 2 forms (for example have 2 elements with the same name), otherwise the default model binder could go berserk. It's up to you to resolve those conflicts if there are any.

How to get rid of this ajax form posting issue?

I am posting a form to controller action. I am getting an error from the controller.
This is the behavior I want:
If error - show the right error message on the same page without any page refresh.
If success - show the success message on the page again no page refresh
what I am getting is that the page gets fully refreshed with different url and shows this:
{"status":"Failed","msg":"\u0027Name\u0027 "}
The url changes to this: ../respond/update which is the action I post to
Basically I want to catch this Failed status and display the msg inside a span.
But why it is taking me to a different page?
Here is the view:
#using (Html.BeginForm("Update", "Respond", FormMethod.Post, new { id = "frmUpdate" }))
{
//have my form here
//submit button
}
Here is the js handler that posts the form:
$('#frmUpdate').submit(function () {
//validation
$.ajax({
url: this.action,
type: this.method,
data: $(this).serialize(),
beforeSend: //show loader
success: function (result) {
alert(result.status);
},
error: function (xhr, status, error) { alert('error'); }
});
return false;
});
Here is controller:
[HttpPost]
public ActionResult Update(ResponseModel model)
{
return Json(new { status="Failed", msg = "Name" });
}
EDIT:
In Firefox it takes to differnt url.
But in IE8 I get this error from jquery itself. Interesting...
Message: Object doesn't support this property or method
Line: 28
Char: 12724
Code: 0
URI: /Content/js/external/jquery-1.6.2.min.js?v=3
I think you should stop the default submit behavior by doing so:
$('#frmUpdate').submit(function (e) {
e.preventDefault();
<your code here>
});
Otherwise the form submit will happen causing the behaviour you want to avoid.
Hope this helps.
#using (Html.BeginForm("Update", "Respond", FormMethod.Post, new { id = "frmUpdate" }))
{
//have my form here
//submit button
}
If you are using submit button than it will post the page. You need to use type button instead of submit.
It will work.
#using (Html.BeginForm("Update", "Respond", FormMethod.Post, new { id = "frmUpdate" }))
{
//have my form here
//use type button
}

MVC 3 Client side validation on jQuery dialog

I am showing lots of form using jquery dialog and I wish to add in client side validation on it. I read through some examples, saying that mvc 3 already somehow support jquery client side validation, but I tried by including the necessary script, and my form like this:
#using (Html.BeginForm("CreateFood", "Home", FormMethod.Post, new { id = "formData" }))
{
#Html.ValidationSummary(false, "Please fix these errors.")
When i try to submit my form without fill in the required field, I still dint get any message. Can anyone give me more idea / explanation / examples on this??
Really needs help here... Thanks...
UPDATE (add in the script for my dialog)
$createdialog.dialog("option", "buttons", {
"Cancel": function () {
//alert('Cancel');
$createdialog.dialog('close');
},
"Submit": function () {
var frm = $('#formData');
$.ajax({
url: '/Food/CreateFood',
type: 'POST',
data: frm.serialize(),
success: $createdialog.dialog('close')
});
}
});
Once dropped, open dialog:
// Once drop, open dialog to create food
options.drop = function (event, ui) {
// Get the ContainerImgName which food dropped at
var cimg = $(this).attr('id');
// Pass in ContainerImgName to retrieve respective ContainerID
// Once success, set the container hidden field value in the FoodForm
$.ajax({
url: '/food/getcontainerid',
type: 'GET',
data: { cImg: cimg },
success: function (result) { $('#containerID').val(result); }
});
clear();
$.validator.unobtrusive.parse($createdialog);
$createdialog.dialog('open');
};
I've faced the same problem, solved with:
$(name).dialog({
autoOpen: true,
width: options.witdth,
heigth: options.height,
resizable: true,
draggable: true,
title: options.title,
modal: true,
open: function (event, ui) {
// Enable validation for unobtrusive stuffs
$(this).load(options.url, function () {
var $jQval = $.validator;
$jQval.unobtrusive.parse($(this));
});
}
});
of course you can add the validation on the close event of the dialog, depends on what you're doing, in my case the popup was just for displaying errors so I've performed validation on load of the content. (this pop up is displaying am Action result)
For every dynamically generated form you need to manually run the validator once you inject this content into the DOM as shown in this blog post using the $.validator.unobtrusive.parse function.
