How I can assign dynamic asp-for in razor view - c#

#for (var i = 1; i < 5; i++)
{
var Tier = $"Tier{i}Score";
<div class="col-12 mt-2">
<div class="row">
<div class="col-2">
<label>#i</label>
</div>
<div class="col-md col-6">
<div class="d-flex align-items-baseline">
<label>#localizer[$"Label_Tier{i}Description"]</label>
<i class="fas fa-info-circle pl-2 cursor-pointer tooltip-ico" data-toggle="tooltip" data-placement="right" title="#localizer[$"Tooltip_Tier{i}Score"]"></i>
</div>
</div>
<div class="col-md col-4">
<input asp-for="#Tier" type="text" class="line-input form-control" maxlength="4" autocomplete="off" />
</div>
</div>
</div>
}
When my div is generated, my id just display as id=Tier, I would like to get result id=Tier1Score, id=Tier2Score, id=Tier3Score and id=Tier4Score. How I can achieve this. Thank you.

You can't also see this answer: Dynamically assigning asp-for variables
But since it's just a TagHelper (it doesn't do anything besides writing correct HTML) you could also write it like this:
<input name="#Tier" id="#Tier" type="text" class="line-input form-control" maxlength="4" autocomplete="off" />
The name is important for the form-post, the id is probably used for javascript thingies you might want to do.

Create a Condition For all non empty fields to be ReandOnly - ASP.NET Core 6.0 MVC

I am developing my first web application with ASP.NET Core 6, and I have a form that shows some fields that I already have information inside of my database.
The problem is: these fields needs to be read-only, because my user needs to considerate the information from my database. If is null, then he needs to insert a value.
Here is an example (consider the field with already set readonly). Most of fields will need this code:
<div class="form-group row">
<div class="col-3">
<label for="Renda Bruta">Associado Desde:</label>
<input type="text" class="form-control">
</div>
<div class="col-3">
<label for="Renda Liquida">Cota Capital</label>
<input type="text" class="form-control">
</div>
<div class="col-6" style="text-align:center">
<label for="ServidorPublico">IAP:</label>
<div class="input-group mb-3">
<input type="text" class="form-control" placeholder="Quantidade" value="#Html.DisplayFor(model => model.iAP.QuantidadeProduto)" ReadOnly="readonly"/>
<input type="text" class="form-control" placeholder="Produtos" value=""#Html.DisplayFor(model => model.iAP.Pro)" ReadOnly="readonly"/>
</div>
</div>
</div>
<div class="form-group row">
<div class="col-4">
<label for="Renda Bruta">Margem Contribuição</label>
<input type="text" class="form-control">
</div>
<div class="col-8" style="text-align:center">
<label for="ServidorPublico">Cheque Especial</label>
<div class="input-group mb-3">
<input type="text" class="form-control" placeholder="Dias de Utilização" />
<input type="text" class="form-control" placeholder="Valor Utilizado" />
<input type="text" class="form-control" placeholder="Valor Contratado" />
</div>
</div>
</div>
I already build the form, and put some fields readonly with ReadOnly="readonly", but is there a way to loop all fields and put readonly with a loop or I really need to write in all fields the code `ReadOnly="readonly" ? My form is really big

Yes, you can set that ReadOnly attribute based on the value of your textbox field.
In this scenario you have to consider two way, either you should consider your textbox name attribute or type="text" attribute. Upon these two very way we will be decided which textbox set to readonly which is not.
For [type='text'] Attribute:
When [type='text'] means we will check all the textbox type of text and check if the textbox have value and set the readonly attribute:
View:
<div class="form-group row">
<div class="col-3">
<label for="Renda Bruta">Associado Desde:</label>
<input type="text" name="Associado" class="form-control">
</div>
<div class="col-3">
<label for="Renda Liquida">Cota Capital</label>
<input type="text" name="Cota" class="form-control">
</div>
<div class="col-6" style="text-align:center">
<label for="ServidorPublico">IAP:</label>
<div class="input-group mb-3">
<input type="text" name="Quantidade" class="form-control" placeholder="Quantidade" value="Test Value" />
<input type="text" name="Produtos" class="form-control" placeholder="Produtos" value="Test Value Products" />
</div>
</div>
</div>
<div class="form-group row">
<div class="col-4">
<label for="Renda Bruta">Margem Contribuição</label>
<input type="text" name="Margem" class="form-control">
</div>
<div class="col-8" style="text-align:center">
<label for="ServidorPublico">Cheque Especial</label>
<div class="input-group mb-3">
<input type="text" name="Dias" class="form-control" placeholder="Dias de Utilização" />
<input type="text" name="Utili" class="form-control" placeholder="Valor Utilizado" />
<input type="text" name="Contra" class="form-control" placeholder="Valor Contratado" />
</div>
</div>
</div>
Script:
#section scripts {
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"></script>
<script src="https://cdn.datatables.net/1.11.3/js/jquery.dataTables.min.js"></script>
<script>
$(document).ready(function () {
$("input[type='text']").each(function (index, item) {
console.log(item);
if ($(item).val() != "") {
$(item).attr('readonly', true);
}
});
});
</script>
}
Note: When will will set readonly to a textbox which has value based on the text type then we have to consider like input[type='text']
For name Attribute:
#section scripts {
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"></script>
<script src="https://cdn.datatables.net/1.11.3/js/jquery.dataTables.min.js"></script>
<script>
$(document).ready(function () {
$("input").each(function (index, item) {
console.log(item);
if ($(item).val() != "") {
$(item).attr('readonly', true);
}
});
});
</script>
}
Note: Remember in this scenario, you need to set name property for your textbox to identify uniquely as you can see I have added name property
Output:
what I understand that you want to make the input field enterable when the value of it is null. this is done by javascript.
I suggest to make all input fields read only.
use javascript to test each field, if its value is null make it enterable.
for example:
<input type="text" id="text1" class="form-control" placeholder="Quantidade" value="#Html.DisplayFor(model => model.iAP.QuantidadeProduto)" ReadOnly="readonly"/>
<script>
window.onload = function() {
if (document.getElementById("text1").value.length == 0)
{
document.getElementById("text1").readOnly = false;
}}
</script>
so basically when the page is loading the script will check if the input is null or not and it will do the action.

Data annotation validation happening on page load in ASP.Net Core

I am facing the issue of data validation being executed on load of a new page even though it is clearly coming from a Get method. Is there something that's triggering the validations on page load?
I have a button on a view to add a new Student record in the new screen :
View :
<a type="button" id="btnAddStudent" href='#Url.Action("Details","Student")' class="btn btn-tertiary" title="Add Student">Add Student</a>
The controller code for the Details action method in Student Controller is as follows.
[HttpGet]
public ActionResult Details(StudentInfo model)
{
//This is populating the model parameters as expected.
helper.StudentInfo(ref model);
return View(model);
}
The view for the Details screen is as follows. The page loads but is throwing validation errors even though it's a Get method.
<form id="frmSubmit" asp-action="Details" asp-controller="Student" method="post">
<input type="hidden" asp-for="StudentId" />
<div class="row">
<div class="col-xs-12">
#Html.ValidationSummary("", new { #class = "alert alert-danger validation" })
</div>
</div>
<div class="row">
<div class="col-xs-12">
<div class="form-group">
<label asp-for="Name">*StudentName</label><br />
<input asp-for="Name" class="form-control" maxlength="100" placeholder="Enter student name..." />
<span asp-validation-for="Name" class="text-danger"></span>
</div>
</div>
</div>
<div class="row">
<div class="col-xs-12">
<div class="form-group">
<label asp-for="AddressLine1"></label><br />
<input asp-for="AddressLine1" class="form-control" placeholder="Enter address..." />
<span asp-validation-for="AddressLine1" class="text-danger"></span>
</div>
</div>
</div>
<div class="row">
<div class="col-xs-12">
<div class="form-group">
<label asp-for="AddressLine2"></label><br />
<input asp-for="AddressLine2" class="form-control" maxlength="100" />
<span asp-validation-for="AddressLine2" class="text-danger"></span>
</div>
</div>
</div>
<div class="box">
<div class="form-group pull-right">
<button type="submit" class="btn btn-primary" value="save"> Save</button>
</div>
</div>
Is there something I am doing wrong? I have verified that the debug control goes to the Get method.There's alos no on load scripts which are doing any sort of validation.
1.Your get method contains the model parameter, when the request hit the method it will judge the ModelState by default. And when you hit the get method by your shared <a>, it send request without any data, so the ModelState is invalid.
2.Default Tag helper displays ModelState's value not Model.
In conclusion, you will render the ModelState error although it is a get method.
Two ways you can resolve this problem. The first way is that you can add ModelState.Clear() before you return View:
public ActionResult Details(StudentInfo model)
{
ModelState.Clear(); //add this....
helper.StudentInfo(ref model);
return View(model);
}
The second way is do not add the model as parameter:
public ActionResult Details()
{
var model = new StudentInfo();
helper.StudentInfo(ref model);
return View(model);
}

C# Razor pages Partial View Model is null on submit

I am new to Razor pages and trying to create a page with a partial view. The partial view has a dropdownlist and a text input for Quantity field and a submit button. The Partial View renders correctly but when I click on the Submit button the Model passed to the Code behind has no value.
Here is the code I have
_PartialAddons.cshtml
#*

}
#model Public.Areas.Register.AddonListDto
<form method="post">
#Html.HiddenFor(Model => Model.Quantity)
<div style="padding:5px;">
<b>NZD $45</b>
</div>
<div>
<div style="padding:5px;">
<select id="skuSelect" asp-for="SelectedSkus" asp-items="#(new SelectList(Model.AddonSkus,"SkuId","SkuName"))" class="form-control">
<option>Please select one</option>
</select>
</div>
<div style="padding:5px;">
<input type="hidden" name="handler" value="Quantity" />
<input asp-for="Quantity" name="Quantity" class="form-control ng-untouched ng-pristine ng-valid" max="999" min="0" style="width:150px;" type="number" value="0" id="#Model.Id">
</div>
</div>
<div style="padding:5px;">
<a class="btn green" asp-page-handler="AddToCart">Add to Cart</a>
</div>
</form>
This is the Main Page
#foreach (var addons in Model.StoreAddonList)
{
<div class="panel card panel-default" style="margin-top:10px;">
<div class="panel-heading card-header" role="tab">
<div class="panel-title">
<div class="accordion-toggle" role="button" aria-expanded="true">

</div>
</div>
<div class="panel-collapse collapse in show" role="tabpanel" style="overflow: visible; height: auto; display: block;" aria-expanded="true" aria-hidden="false">
<div class="panel-body card-block card-body">

}
</div>
</div>
<div style="clear:both;">
</div>
</div>
</div>
</div>
</div>
}
This is the Index.cshtml.cs to handle the submit
public ActionResult OnGetAddToCart(AddonListDto addOnList)
{
var sass = Quantity;
var tass = SelectedSkus;
return null;
}
The AddonListDto is null on the OnGetAddToCart Method. Have been trying to get this working for the past two days. Any help would be greatly appriciated
If you want to submit your data, you need to use OnPost instead of OnGet in razor pages and set the handler name in the <form> tag. For example:
handler:
public ActionResult OnPostAddToCart(AddonListDto addOnList)
partial view:
#model Public.Areas.Register.AddonListDto
<form method="post" asp-page-handler="AddToCart">
#Html.HiddenFor(Model => Model.Quantity)
<div style="padding:5px;">
<b>NZD $45</b>
</div>
<div>
<div style="padding:5px;">
<select id="skuSelect" asp-for="SelectedSkus" asp-items="#(new SelectList(Model.AddonSkus,"SkuId","SkuName"))" class="form-control">
<option>Please select one</option>
</select>
</div>
<div style="padding:5px;">
<input type="hidden" name="handler" value="Quantity" />
<input asp-for="Quantity" name="Quantity" class="form-control ng-untouched ng-pristine ng-valid" max="999" min="0" style="width:150px;" type="number" value="0" id="#Model.Id">
</div>
</div>
<div style="padding:5px;">
<input type="submit" value="Add To Cart" class="btn btn-primary" />
</div>
</form>

Form fields from the ASP.NET View appear NULL in the Controller

The form fields do not return the value of the form even thought the asp-controller and asp-action is stated.
The form does go to the right controller function and returns the right view, however, it does the form object is NULL.
#using ActionAugerMVC.Models
#model Tuple<IEnumerable<Cities>,Content,IEnumerable<Content>,Quote>
#addTagHelper "*,Microsoft.AspNetCore.Mvc.TagHelpers"
<div class="sidebar__item">
<p class="subheading">Instant Quote Request</p>
<form class="register__form" role="form" asp-controller="Plumbing" asp-action="QuoteForm" method="post">
<div class="text-danger" asp-validation-summary="All"></div>
<div class="form-group">
<label class="sr-only">Full Name </label>
<input asp-for="#Model.Item4.FullName" type="text" class="form-control" placeholder="Full name">
</div>
<div class="form-group">
<label class="sr-only">Your phone</label>
<input asp-for="#Model.Item4.Phone" type="tel" class="form-control" placeholder="Your phone">
<span asp-validation-for="#Model.Item4.Phone" class="text-danger"></span>
</div>
<div class="form-group">
<label class="sr-only">E-mail</label>
<input asp-for="#Model.Item4.Email" type="email" class="form-control" placeholder="E-mail">
<span asp-validation-for="#Model.Item4.Email" class="text-danger"></span>
</div>
<div class="form-group">
<label class="sr-only">Your Message</label>
<input asp-for="#Model.Item4.Message" type="text" class="form-control" placeholder="Your Message">
</div>
<input type="submit" value="Get a Quote Now" class="btn btn-accent btn-block">
</form>
</div> <!-- .sidebar__item -->
And the Controller looks like this, with the Quote object being null.
The hard coded, values appear correctly in the view, but the Quote object returned by the form is null.
[HttpPost]
public IActionResult QuoteForm(Quote quote)
{
if (ModelState.IsValid)
{
/* quote.FullName = "Umar Aftab";
quote.Email = "test#email.com";
quote.City = "Calgary";
quote.Message = "Test Message";
quote.Phone = "6474543769";
*/
}
return View(quote);
}
The issue is your use of a Tuple as your view's model combined with asp-for. For example, with something like:
<input asp-for="#Model.Item4.FullName" type="text" class="form-control" placeholder="Full name">
The name of the input is going to end up as Item4.FullName. However, your action accepts only Quote, which means the modelbinder needs the input to be named just FullName in order to bind it properly. You either need to accept the same model the view uses (though I've never tried posting a Tuple so not sure if that will even work), or you can use a partial view to work around the issue.
Essentially, you just would need to move all the fields related to just Quote to a partial view. Then, in this view, you can include them via:
#Html.Partial("_QuoteFields", Model.Item4)
That should be enough psych Razor out enough to just name the fields like FullName instead of Item4.FullName. If it's not, then you may need to reset the HtmlFieldPrefix, via:
#Html.Partial("_QuoteFields, Model.Item4, new ViewDataDictionary(ViewData) { TemplateInfo = new TemplateInfo { HtmlFieldPrefix = "" } })
The model on your view is different than the model you're trying to bind it to in the controller. You're not going to get the key/value pairs to match up
Put your razor in a partial view with Quote as the model and try that.
_QuoteForm.cshtml
#model Quote
<div class="form-group">
<label class="sr-only">Full Name </label>
<input asp-for="FullName" type="text" class="form-control" placeholder="Full name">
</div>
<div class="form-group">
<label class="sr-only">Your phone</label>
<input asp-for="Phone" type="tel" class="form-control" placeholder="Your phone">
<span asp-validation-for="Phone" class="text-danger"></span>
</div>
<div class="form-group">
<label class="sr-only">E-mail</label>
<input asp-for="Email" type="email" class="form-control" placeholder="E-mail">
<span asp-validation-for="Email" class="text-danger"></span>
</div>
<div class="form-group">
<label class="sr-only">Your Message</label>
<input asp-for="Message" type="text" class="form-control" placeholder="Your Message">
</div>

Inline form not working correctly

Trying to get an inline form out of bootstrap using the class form-inline. However, I'm encountering some unexpected behavior and I'm using exactly the same code as listed on the Boostrap official page.
This is what I get:
The code:
#using (Html.BeginForm("Edit", "Index", FormMethod.Post, new { #class = "form-inline" }))
{
<div class="form-group">
<label for="new-value">Enter new value: </label>
<input type="text" id="new-value" class="form-control" />
</div>
<div class="checkbox">
<label>
Public: <input type="checkbox" />
</label>
</div>
<input type="submit" class="btn btn-primary" />
}
When I remove the form-control class from the text box I get the wanted result, but I don't have the cool text box then:
I'm aware of the warning from bootstrap:
This only applies to forms within viewports that are at least 768px wide.
But this is on a large screen and the form width is 1160px.
I have edited your code.
Hope this is what you wanted!
HTML
<form class="form-inline">
<div class="form-group">
<label for="new-value">Enter new value: </label>
<input type="text" id="new-value" class="form-control" />
</div>
<div class="form-group">
<div class="checkbox">
<label> Public:
<input type="checkbox" />
</label>
</div>
</div>
<div class="form-group">
<input type="submit" class="btn btn-primary" />
</div>
</form>
