Unobtrusive JQuery Validation not working in popup PartialViews [duplicate] - asp.net-mvc

This question already has an answer here:
Required field validations not working in JQuery Popup MVC 4
(1 answer)
Closed 7 years ago.
I have the following a partial view in asp.net 5 mvc 6 project. The partial view is shown as a jquery ui dialog and is loaded dynamically when the user clicks a button in the parent view page.The issue is that the Unobtrusive JQuery Validation does not work after I enter invalid entires and clicked submit.
I have done all the procedures needed to make Unobtrusive JQuery Validation work and it works in Non partial views.
Here is my code
my partial view name EquipmentEditTemplate.cshtml
#model MyProject.Models.EquipmentViewModel
#*<form role="form" name="FormPost" asp-controller="Asset" method="post" asp-action="SaveEq" data-ajax="true" id="FrmGrid_grdLocation1" class="FormGrid form-horizontal" style="width:477px;height:703px;">*#
#*<form asp-controller="Asset" asp-action="SaveEq" method="post" style="width:600px;height:703px;" class="form-horizontal" >*#
<div class="FormError bg-danger" style="display:none;"></div><div class="tinfo topinfo"></div><div class="modal-body">
<div style="margin-left:15px;">
<div class="form-group">
<label asp-for="EquipmentID" class="col-sm-2 control-label">Equipment ID:</label>
<div class="col-sm-10">
<input asp-for="EquipmentID" class="FormElement form-control" />
<span asp-validation-for="EquipmentID" class="text-danger"></span>
</div>
</div>
<div class="form-group">
<label asp-for="Email" class="col-sm-2 control-label">Email:</label>
<div class="col-sm-10">
<input asp-for="Email" class="FormElement form-control" />
</div>
</div>
<div class="form-group">
<label asp-for="Department" class="col-sm-2 control-label">Department:</label>
<div class="col-sm-10">
<input type="text" id="Department" name="Department" value="#Model.Department" role="textbox" class="FormElement form-control">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Sign in</button>
</div>
</div>
</div>
</form>
I have the code below in the main view as shown I have included the validation scripts in there equipment.cshtml
#{
ViewData["Title"] = "Equipment";
}
<h2>#ViewData["Title"].</h2>
<h3>#ViewData["Message"]</h3>
#section scripts{
#{await Html.RenderPartialAsync("_ValidationScriptsPartial"); }
<script src="~/js/equipment.js" type="text/javascript"></script>
}
I have my model class defined as follows
public class EquipmentViewModel
{
[Required]
public int EquipmentID { get; set; }
[EmailAddress]
public string Email{ get; set; }
public int Description{ get; set; }
}
}

When you've loaded a form in to your DOM dynamically then add the below line at the end of your partial view.
$(document).ready(function() {
$.validator.unobtrusive.parse($('#yourform'));
});

Is it possible to generate new instances of the same form by clicking a button?

I'm working on a use case in my animal shelter web application where customers are able to register one or more animals at the same time. Ideally I'd like a button on the bottom left that generates another instance of the same form when clicked, so that multiple animal registrations can be saved to the database at once.
NewAnimalRegistration.cshtml:
#model NewAnimalRegistrationViewModel
<html>
<head>
<title>Register an animal</title>
<link rel="stylesheet" href="~/css/style.css"/>
</head>
<body>
<div class="container py-5">
<div class=" row">
<div class="col-md-10" mx-auto>
<div asp-validation-summary="All"></div>
<h1>Animal registration</h1>
<p>

check if there is room for your animal.

Is there a way to do this in .NET Core MVC? If yes, will I simply receive a list of all animal registrations through which I can simply loop and add them all to the database?
I made a demo based on your description, you can refer to it:
Model:
public class NewAnimalRegistrationViewModel
{
public int Id { get; set; }
public string Name { get; set; }
public string Gender { get; set; }
public string Type { get; set; }
public bool IsNeutered { get; set; }
public string Reason { get; set; }
}

ASP.NET Core MVC validate not required fields

My page is validating a field that is not required when I submit, even though there is no validation configured for this field.

[Required(ErrorMessage = "O campo número é obrigatório")]
public string Numero { get; set; }
[DisplayName("Área")]
public int IdArea { get; set; }
}
Controller
In Controller Create method, nothing happens, because all validation takes place on the client side.
[Route("novo-processo")]
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create(ProcessoViewModel processoViewModel)
{
try
{
if (!ModelState.IsValid) return View(processoViewModel);
await _processoBLL.Insert(_mapper.Map<ProcessoDTO>(processoViewModel));
if (!ValidOperation()) return View(processoViewModel);
return RedirectToAction(nameof(Index));
}
catch
{
return View();
}
}
Inspecting in Chrome I see this generated html for the field that I didn't require validation, I don't know if it could be something related to Jquery.Unobtrusive but I can't remove it either because other fields will be validated.
<select id="slcArea" class="form-control select2 select2-hidden-accessible input-validation-error" data-val="true" data-val-required="The Área field is required." name="IdArea" data-select2-id="slcArea" tabindex="-1" aria-hidden="true" aria-describedby="slcArea-error" aria-invalid="true"></select>
Why is this validation taking place that I have not defined the field as required?
Not nullable properties (that is properties with value types) are always required. Use nullable types (reference types) for properties if they should not be required - eg. int?.
You can always use formnovalidate on any input you don't want validated.
<input asp-for="Numero" formnovalidate="formnovalidate" class="form-control" />
This way there is no need to change your model. This is demonstrated at W3Schools

How do I redirect from an MVC Post Action back to the bootstrap popup modal partial view where the post came from?

How do I redirect from an MVC Post Action back to the bootstrap popup modal partial view where the post came from?
Here is the PartialView sitting in the Bootstrap modal popup on the page.
It has a div with a validation taghelper waiting for any model errors.
#model CreateRoleViewModel
<div class="panel panel-primary partialModalFormDivs">
#Html.Partial("_ModalHeader",
new ModalHeader
{
Heading = "ADD ROLE",
glyphiconClass = "glyphicon glyphicon-random"
}
)
<div class="panel-body">
<div asp-validation-summary="All" class="text-danger"></div>
<form asp-action="CreateRole" method="post">
<div class="form-group">
<label asp-for="RoleName"></label>
<input asp-for="RoleName" class="form form-control" />
</div>
<div class="modal-footer">
<button type="submit" class="btn btn-primary">Create</button>
<a asp-action="Index" class="btn btn-default">Cancel</a>
</div>
</form>
</div>
</div>
It posts to this action:
[HttpPost]
public async Task<IActionResult> CreateRole(CreateRoleViewModel createRoleViewModel)
{
if (ModelState.IsValid)
{
IdentityRole role = new IdentityRole(createRoleViewModel.RoleName);
IdentityResult result
= await _roleManager.CreateAsync(role);
if (result.Succeeded)
{
return RedirectToAction("Index");
}
else
{
foreach (IdentityError error in result.Errors)
{
ModelState.AddModelError("", error.Description);
}
}
}
return View(createRoleViewModel);
}
I can return a PartialView like this at the end:
return View("_CreateRole", createRoleViewModel);
But then the whole page is cleared and this partial is returned with no layout file.
How can I return the results back to the modal popup window.
I understand the problem and the current behavior. But has anyone else solved this?
I think what you want to do is an ajax post and then just return a partial view and replace the form. The form should be inside a container div with an id that is used to replace its contents with the ajax post result. To do this you need to include the jquery unobtrusive ajax script which will auto wire the ajax based on the data-* attributes on the form as shown below
<div class="panel-body">
<div asp-validation-summary="All" class="text-danger"></div>
<div id="resultcontainer">
<form asp-action="CreateRole" method="post"
data-ajax="true"
data-ajax-method="POST"
data-ajax-mode="replace"
data-ajax-update="#resultcontainer"
>
<div class="form-group">
<label asp-for="RoleName"></label>
<input asp-for="RoleName" class="form form-control" />
</div>
<div class="modal-footer">
<button type="submit" class="btn btn-primary">Create</button>
<a asp-action="Index" class="btn btn-default">Cancel</a>
</div>
</form>
</div>
</div>
and don't forget to return a partial view
return PartialView(createRoleViewModel);

Input validation generating data-* attributes ONLY on Primary key and checkbox type input tags

I've created a sample ASP.NET MVC Core 1.1 web app created using VS2015-Update3. It generates input tags with data -* attributes only on a model property that is a Primary Key, and on a property that is of type bool. For instance, in the following example the generated html (shown below) is showing the data-attributes only on the input tag generated for properties MyEntityId and Prop2 of the model. NOTE: I'm using the default ASP.NET Core Web Application template that automatically installs Jquery, Bootstrap, etc.
Model:
public class MyEntity
{
public int MyEntityId { get; set; }
public string Prop1 { get; set; }
[Column(TypeName = "char(2)")]
[RegularExpression(#"^[0-9]{2,2}$", ErrorMessage = "Must enter two digit numbers"), StringLength(2)]
public string TestCode { get; set; }
public DateTime? StartDate { get; set; }
public bool Prop2 { get; set; }
}
View
<form asp-controller="TestController" asp-action="TestAction" method="post" class="form-horizontal">
<div asp-validation-summary="All" class="text-danger"></div>
<div><input type="hidden" asp-for="MyEntityId" /></div>
<div class="form-group">
<label asp-for="Prop1" class="col-md-2 control-label"></label>
<div class="col-md-10">
<input asp-for="Prop1" class="form-control" style="margin-top:15px;" />
<span asp-validation-for="Prop1" class="text-danger"></span>
</div>
</div>
<div class="form-group">
<label asp-for="TestCode" class="col-md-2 control-label"></label>
<div class="col-md-2">
<input asp-for="TestCode" class="form-control" />
<span asp-validation-for="TestCode" class="text-danger"></span>
</div>
</div>
<div class="form-group">
<label asp-for="StartDate" class="col-md-2 control-label"></label>
<div class="col-md-10">
<input asp-for="StartDate" type="date" class="form-control" />
<span asp-validation-for="StartDate" class="text-danger"></span>
</div>
</div>
<div class="form-group">
<label asp-for="Prop2" class="col-md-2 control-label"></label>
<div class="col-md-1">
<input asp-for="Prop2" class="form-control" style="zoom:0.5;margin-top:25px;" />
<span asp-validation-for="Prop2" class="text-danger"></span>
</div>
</div>
<button type="submit" name="submit" value="testVal">Save</button>
</form>
Generated Html:
<div><input type="hidden" data-val="true" data-val-required="The MyEntityId field is required." id="MyEntityId" name="MyEntityId" value="54321"></div>
<div class="form-group">
<label class="col-md-2 control-label" for="StateName">Prop1</label>
<div class="col-md-2">
<input class="form-control" readonly="" type="text" id="Prop1" name="Prop1" value="TestVal">
<span class="text-danger field-validation-valid" data-valmsg-for="Prop1" data-valmsg-replace="true"></span>
</div>
</div>
<div class="form-group">
<label class="col-md-2 control-label" for="TestCode">TestCode</label>
<div class="col-md-2">
<input class="form-control" type="text" id="TestCode" name="TestCode" value="">
<span class="text-danger field-validation-valid" data-valmsg-for="TestCode" data-valmsg-replace="true"></span>
</div>
</div>
<div class="form-group">
<label class="col-md-2 control-label" for="StartDate">Start Date</label>
<div class="col-md-10">
<input type="date" class="form-control" id="StartDate" name="StartDate" value="2015-10-01">
<span class="text-danger field-validation-valid" data-valmsg-for="StartDate" data-valmsg-replace="true"></span>
</div>
</div>
<div class="form-group">
<label class="col-md-2 control-label" for="Prop2">Test Prop2</label>
<div class="col-md-1">
<input class="form-control" data-val="true" data-val-required="Test Prop2 is required." id="Prop2" name="Prop2" style="zoom:0.5;margin-top:25px;" type="checkbox" value="true">
<span class="text-danger field-validation-valid" data-valmsg-for="Prop2" data-valmsg-replace="true"></span>
</div>
</div>
I'm assuming your issue is that TestCode does not have validation on it, despite having both RegularExpression and StringLength attributes applied. MyEntityId and Prop2 are non-nullable, so there's an implicit required validation for those, while Prop1 and StartDate are nullable and do not have any explicit validation applied. As a result, those are rightly not validated.
TestCode is weird, though. I'm not sure you'd actually get data-* attributes, as both the regular expression and string length can be satisfied using the HTML attributes pattern and maxlength, respectively. But, you should then have pattern and maxlength applied to the input for TestCode which is not the case.
According to the docs, the code you have should work, and at the least, it seems that StringLength is applied via data-val-maxlength rather than (or perhaps in addition to) using the maxlength attribute. There's either some bug at play, or there's something else in your codebase that is preventing the correct behavior from occurring. However, without more code, it's impossible to say.

MVC 5, Using Checkbox for same model property twice in a page but inside different forms

Model property which I intend to use inside two forms
public class TestModel
{
[Display(Name = "Terms Accepted")]
[Range(typeof(bool), "true", "true", ErrorMessage = "You need to accept terms and conditions to proceed!")]
public bool TermsAccepted { get; set; }
}
view Page
<form id="form1">
<div class="row">
<div class="col-md-3">
#Html.CheckBoxFor(m => m.TermsAccepted) I accept terms and conditions
#Html.ValidationMessageFor(m => m.TermsAccepted, new { #id = "chk1" })
</div>
<div class="col-md-3">
<input type="submit" id="button1" onclick="return isFormValid('form1');" value="Submit Form 1"/>
</div>
</div>
</form>
<form id="form2">
<div class="row">
<div class="col-md-3">
#Html.CheckBoxFor(m => m.TermsAccepted, new { #id = "chk2" }) I accept terms and conditions
#Html.ValidationMessageFor(m => m.TermsAccepted)
</div>
<div class="col-md-3">
<input type="submit" id="button2" onclick="return isFormValid('form2');" value="Submit Form 2"/>
</div>
</div>
</form>
When this UI is rendered on the page, checkbox inside the 1st form do contains attributes for RangeDataAnnotation while checkbox inside 2nd form doesn't have any attributes for data annotation. So this results into 2nd form doesn't throw any validation on submission.
Html of checkboxes which get rendered on UI
Inside form 1:
<input name="TermsAccepted" class="input-validation-error" id="chk1" aria-describedby="TermsAccepted-error" type="checkbox" value="true" data-val="true" data-val-range-min="True" data-val-range-max="True" data-val-range="You need to accept terms and conditions to proceed!">
Inside form 2:
<input name="TermsAccepted" id="chk2" type="checkbox" value="true">
Any suggestions to make this work in both forms?
