how to fix delete record using partial view? - asp.net

I want to delete the record from the table with modal but the partial view is not displayed in modal ...
How can I solve this problem !?
And that I can not use onClick !!!
this action for delete in controller:
public IActionResult DelPlatform(int? id)
{
if (id == null)
{
return NotFound();
}
PR_Platform platformModel = _Iunit.PlatformsRepository.GenGetById(id);
if (platformModel == null)
{
return NotFound();
}
return View(platformModel);
}
[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult DelPlatform(int id)
{
_Iunit.PlatformsRepository.GenDeleteById(id);
return RedirectToAction(nameof(PlatformList));
}
this delete button in index view:

How to push ID into form in popup using ASP.NET Core MVC?

I created a delete method where first I ask the user If he/she wants to delete the record. If user clicks yes, I will delete the record using the form but in order to delete it , I must send the ID inside the modal. How can I do that ? If I use foreach for modal it says something like too many request and tries to delete all the records, not the only one I ask.
<br />
<a asp-controller="Banner" asp-action="Create" style="float:right" class="btn btn-success">Create</a></td>
</br>
<table class="table table-bordered">
<thead>
<tr>
<th>Redirect Url</th>
</tr>
</thead>
<tbody>
#foreach (var item in Model.Banners)
{
<tr>
<td>#item.RedirectUrl</td>
<td>
<a asp-controller="Banner" asp-action="Update" asp-route-id="#item.Id" class="btn btn-info">Update</a>
<button type="button" class="btn btn-primary" data-toggle="modal" id="#item.Id" data-target="#exampleModal">
Delete
</button>
<a asp-controller="Banner" asp-action="Delete" data-toggle="modal" data-target="#exampleModal" asp-route-id="#item.Id" class="btn btn-info">Deletee</a>
</td>
</tr>
}
</tbody>
</table>
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">

</div>
<div class="modal-body">
#using (Html.BeginForm("Delete", "Banner", FormMethod.Post, new { #class = "form-horizontal", enctype = "multipart/form-data" }))
{
<p>Are you sure you want to delete this record? </p>

<button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-primary">Yes</button>

{
var result = await _mediator.Send(new DeleteBannertByIdCommand(id));
}

return Redirect("index");
}
You can use JavaScript to set the value of a hidden input element inside your modal form when a delete button is clicked.
<!-- ... -->
<button data-id="#item.Id" type="button" class="btn btn-primary delete-button" data-toggle="modal" data-target="#exampleModal">
Delete
</button>
<!-- ... -->
<!-- ... -->
<div class="modal-body">
#using (Html.BeginForm("Delete", "Banner", FormMethod.Post, new { #class = "form-horizontal", enctype = "multipart/form-data" }))
{
<input type="hidden" id="delete-input" name="id" />
<p>Are you sure you want to delete this record? </p>
<div>
<button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-primary">Yes</button>
</div>
}
</div>
<!-- ... -->
#section Scripts {
<script>
const onDeleteButtonClicked = function () {
var deleteInput = document.getElementById('delete-input');
deleteInput.value = this.dataset.id;
};
const deleteButtons = document.querySelectorAll('.delete-button');
deleteButtons.forEach(function (deleteButton) {
deleteButton.onclick = onDeleteButtonClicked;
});
</script>

Model popup is not showing in Blazor with #ref attribute

I have created a shared component for Model popup and using #ref attribute while registering the component. I am not getting any error but my model popup is not showing.
Below the code for CofirmationBox
#inherits ConfirmModelBoxBase
#if (ShowConfirmationBox)
{
<div class="modal fade show d-block" id="exampleModal" tabindex="-1" role="dialog">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Confirm Delete</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">

</button>
</div>
<div class="modal-body">
Are you sure want to delete the record?
</div>
<div class="modal-footer">

<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
}
public class ConfirmModelBoxBase : ComponentBase
{
[Parameter] public bool ShowConfirmationBox { get; set; }
[Parameter] public EventCallback<bool> CoonfirmationChanged { get; set; }
public void Show()
{
ShowConfirmationBox = true;
StateHasChanged();
}
}
Registering the Component on My employee list page
<ConfirmModelBoxBase #ref="DeleteConfirmation">
</ConfirmModelBoxBase>
Server side call to show the popup
[Parameter] public ConfirmModelBoxBase DeleteConfirmation { get; set; }
protected void btnDelete_Click()
{
DeleteConfirmation.Show();
}
According to your HTML code, you use bootstrap modal.
You don't need a #ref to open it but some JSInterop:
Add a scripts tags in your _Host.html or index.hmtl to load bootstrap js and its dependency. Bootstrap js required JQuery and Popper.js.
<head>
...
<script src="//code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js" integrity="sha384-UO2eT0CpHqdSJQ6hJty5KVphtPhzWj9WO1clHTMGa3JDZwrnQq4sF86dIHNDz0W1" crossorigin="anonymous"></script>
<script src="//stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js" integrity="sha384-JjSmVgyd0p3pXB1rRibZUAYoIIy6OrQ6VrjIEaFf/nJGzIxFDsf4x0xIM+B07jRM" crossorigin="anonymous"></script>
</head>
Add a js interop file in your wwwroot folder
bootstrapInteropt.js
window.bootstrapInteropt = {
showModal: id => {
$(`#${id}`).modal('show');
},
hideModal: id => {
$(`#${id}`).modal('hide');
}
};
Add a script tag to load this js in your _Host.html or index.hmtl
<body>
<app>
</app>
<script src="bootstrapInteropt.js"></script>
...
</body>
Call the js fonction to show the popup
#inject IJSRuntime _jsRuntime
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" data-backdrop="false">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Confirm Delete</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
Are you sure want to delete the record?
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
#code {
[Parameter] public EventCallback<bool> CoonfirmationChanged { get; set; }
public Task Show()
{
return _jsRuntime.InvokeVoidAsync("bootstrapInteropt.showModal", "exampleModal");
}
public Task Hide()
{
return _jsRuntime.InvokeVoidAsync("bootstrapInteropt.hideModal", "exampleModal");
}
}
I believe the pattern is to use the property + "Changed" for the EventCallback.
[Parameter] public bool ShowConfirmationBox { get; set; }
[Parameter] public EventCallback<bool> ShowConfirmationBoxChanged { get; set; }
I created a simplified version of this code at https://blazorfiddle.com/s/hd6sbj44
You can user JSInterop, agua from mars was showing in the answer. If you want to avoid JSInterop you can try this
public class ConfirmModelBoxBase : ComponentBase
{
//[Parameter] // You don't need because you are not passing the argument with Component you are updating using Show function
public bool ShowConfirmationBox { get; set; }
//[Parameter] // You don't need
//public EventCallback<bool> ShowConfirmationBoxChanged { get; set; }
public void Show()
{
ShowConfirmationBox = true;
StateHasChanged();
}
}
ConfirmDelete.razor which will inherit ConfirmModelBoxBase
#*ConfirmDelete.razor*#
#inherits ConfirmModelBoxBase
#if (ShowConfirmationBox)
{
<div class="modal fade show d-block" tabindex="-1">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">Confirm Delete</h4>
<button type="button" class="close" #onclick="OnCanceled">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
Are you sure want to delete the recored?
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" #onclick="OnCanceled">Cancel</button>
<button type="button" class="btn btn-secondary" #onclick="OnSaved">Save Changed</button>
</div>
</div>
</div>
</div>
<div class="modal-backdrop fade show"></div>
}
#code {
private void OnCanceled(MouseEventArgs e)
{
ShowConfirmationBox = false;
}
private void OnSaved(MouseEventArgs e)
{
ShowConfirmationBox = false;
//Save changes
}
}
Sample.razor
<ConfirmDelete #ref="_confirm">
</ConfirmDelete>
<button #onclick="OnClicked">Click</button>
#code{
private ConfirmModelBoxBase _confirm;
private void OnClicked()
{
_confirm.Show();
}
}

User photo disappears when I change the password

I have a form where the user's photo appears. Every time I change the user password, the photo disappears from the form. I already tried to take the image of the form but it did not solve. The password change is done through onSubmit.
HTML:
<form (ngSubmit)="onSubmit($event)">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Configuração do Usuário: <b> {{userId?.name}} </b></h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<div class="example-container" style="width: 100%; margin: auto; margin-top: 2%">
<img class="img-modal" style="border-radius: 50%; width: 60px; height: 60px;" src={{userId?.photo}}>
<div class="example-container password-width">
<mat-form-field>
<input matInput placeholder="Alterar a Senha" [type]="hide ? 'text' : 'password'" [(ngModel)]="senha" name="senha">
<mat-icon matSuffix (click)="hide = !hide">{{hide ? 'visibility' : 'visibility_off'}}</mat-icon>
</mat-form-field>
</div>
<app-panel-config-user></app-panel-config-user>
</div>
</div>
<div class="modal-footerButtonConfig">
<button type="button" class="btn btn-danger btn-sm buttonConfig" *ngIf="userId?.status == 1">Desativar
Usuário</button>
<button type="button" class="btn btn-success btn-sm buttonConfig" *ngIf="userId?.status == 0">Ativar
Usuário</button>
<button type="button" class="btn btn-sm buttonConfig buttonColor" style="background-color: #6239BD; color: white" *ngIf="userId?.is_admin == 0">Tornar Administrador</button>
<button type="button" class="btn btn-sm buttonConfig buttonColor" style="background-color: #6239BD; color: white" *ngIf="userId?.is_admin == 1">Remover Administrador</button>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary btn-sm" data-dismiss="modal">Fechar</button>
<button type="submit" class="btn btn-sm buttonColor" style="background-color: #6239BD; color: white">Salvar</button>
</div>
</form>
Code change password:
onSubmit(
userPass: UserPass,
messageSucess: string = 'Senha alterada com Sucesso!',
messageError: string = 'Falha ao alterar a senha.',
action: string = '') {
userPass.password = this.senha;
return this.userService.putPass(this.idUser, userPass).subscribe(response => {
if (!response) {
console.log(Error);
} else {
this.userId = response;
if (this.userId['success'] === true) {
this.senha = '';
this.snackBar.open(messageSucess, action, {
duration: 4000,
panelClass: ['success-class']
});
} else {
this.snackBar.open(messageError, action, {
duration: 4000,
panelClass: ['error-class']
});
}
}
});
}
Your problem is the line
this.userId = response;
You are setting the userId to the response ({success: true}) - but the response isn't a userId!
Remove this line, and it should work again.

When model is not valid, return to partial view inside a view, with error message using asp.net core

I´ve got a modal boostrap. I want to show the error of validation on boostrap modal. But when I leave the model empty and click on submit button Its just viewed as a standalone page.
Partial view:
#model WebApplication1.Models.Book
<form asp-controller="Home" asp-action="AddBook"
data-ajax="true" data-ajax-method="POST" data-ajax-mode="replace" data-ajax-update="#frmaddbook">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title" id="myModalLabel">Header of Modal</h4>
</div>
<div class="modal-body form-horizontal" id="frmaddbook ">
<span class="alert-danger">
#Html.ValidationSummary()
</span>
<div class="row">
<div class="form-group">
<label asp-for="BookName" class="col-lg-3 col-sm-3 control-label"></label>
<div class="col-lg-6">
<input asp-for="BookName" class="form-control" />
<span asp-validation-for="BookName" class="text-danger"></span>
</div>
</div>
<div class="form-group">
<label asp-for="BookDescription" class="col-lg-3 col-sm-3 control-label"></label>
<div class="col-lg-6">
<input asp-for="BookDescription" class="form-control" />
<span asp-validation-for="BookDescription" class="text-danger"></span>
</div>
</div>
</div>
</div>
<div class="modal-footer">
<input type="submit" class="btn btn-primary" value="Submit" />
</div>
Index View :
<div class="panel panel-primary">
<div class="panel-body">
<div class="btn-group">
<a class="btn btn-primary marginbutoon" id="showBookgroup" data-toggle="modal" asp-action="AddBook"
data-target="#modal-book">
<i class="glyphicon glyphicon-plus"></i>
Add Book
</a>
</div>
</div>
i use this libraries at top of index view:
jquery.unobtrusive-ajax.min.js
jquery.validate.unobtrusive.min.js
and use at the bottom of index view:
<script src="~/js/book-index.js"></script>
book-index.js:
(function ($) {
function Home() {
var $this = this;
function initilizeModel() {
$("#modal-book").on('loaded.bs.modal', function (e) {
}).on('hidden.bs.modal', function (e) {
$(this).removeData('bs.modal');
});
}
$this.init = function () {
initilizeModel();
}
}
$(function () {
var self = new Home();
self.init();
})
}(jQuery))
Controller:
[HttpGet]
public IActionResult AddBook()
{
var b = new Book();
return PartialView("_AddBook", b);
}
[HttpPost]
[ValidateAntiForgeryToken]
//[HandleError]//not in core
public IActionResult AddBook(Book model)
{
if (ModelState.IsValid)
{
return RedirectToAction("Index");
}
return PartialView("_AddBook", model);
}
Model :
public class Book
{
[Key]
public int BookId { get; set; }
[Display(Name = "Book Name :")]
[Required(ErrorMessage = "Enter Book Name Please ")]
public string BookName { get; set; }
[Display(Name = "Book Description")]
[Required(ErrorMessage = "Enter Book Description Please ")]
public string BookDescription { get; set; }
}
My code is shown above. How can i show validation error in modal partial view ?
You can set the Id of form as the data-ajax-update property value of the form , which is ajaxified. This value will be used as the jQuery selector when the result is received from the ajax call.
#model Book
<form asp-controller="Home" asp-action="AddBook" id="myform"
data-ajax="true" data-ajax-method="POST"
data-ajax-mode="replace" data-ajax-update="#myform">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title" id="myModalLabel">Add Book</h4>
</div>
<div class="modal-body form-horizontal" id="frmaddbook ">
<span class="alert-danger">
#Html.ValidationSummary()
</span>
<div class="row">
<div class="form-group">
<label asp-for="BookName" class="col-sm-3 control-label"></label>
<div class="col-lg-6">
<input asp-for="BookName" class="form-control" />
<span asp-validation-for="BookName" class="text-danger"></span>
</div>
</div>
</div>
</div>
<div class="modal-footer">
<input type="submit" class="btn btn-primary" value="Submit" />
</div>
</form>
Now when you submit the form and model state validation fails, the action method code will return the partial view result with the validation error messages (generated by the validation helpers) and the jquery.unobtrusive-ajax.js library code will replace (because we specified that with data-ajax-mode="replace") the content of the result of the jquery selector #data-ajax-update (the form tag and it's inner contents) with the response coming back from the server.

The issue I have is that, for example, I entered an incorrect username/password combination, the form validates, but the modal window closes. Is there a way to re-open the modal window after the form has posted if the validation triggered an error?
You could add a property named IsModalShown i.e.
public class AModel
{
public bool IsModalShown { get; set; }
}
Render this as a hidden for in your view i.e.
#Html.HiddenFor(m => m.IsModalShown)
When the modal is opened set the hidden value to true, this will enable the modal state to be posted back to the controller action i.e.
$('#modalLogin').on('show.bs.modal', function (e) {
$('#IsModalShown').val(true);
})
Please note the above will depend on the version of bootstrap you are using but there are other docs on the official site
Then add the following to your view that automatically pops it up
$(function(){
#if(Model.IsModalShown)
{
$('#signin_modal').modal('show');
}
});
I had a similar problem, but didn't have a model in view. Posting my solution, in case it would help someone. I wanted to show an error message stored in TempData (in case of wrong login/password combination, on which Batuta was asking).
Controller:
public ActionResult SignIn(string login, string password)
{
if (Membership.ValidateUser(login, password))
{
// something
}
else
{
TempData["message-error"] = "Wrong combination";
}
return RedirectToAction("Index", "Home");
}
Showing the message in modal window:
#if (TempData["message-error"] != null)
{
#TempData["message-error"]
}
Opening modal in index:
#if (TempData["message-error"] != null)
{
<script type="text/javascript">
$('#myModal').modal('show');
</script>
}
Maybe not that clean, but works for me.
