I have this ViewModels:
Inside "EMPRESA" I got a lot of properties that work just fine.
public class EmprViewModel
{
public int ID_EMP { get; set; }
public string NOME { get; set; }
public List<TelasViewModel> Telas;
}
public class TelasViewModel
{
public int ID_TELA { get; set; }
public string TITULO { get; set; }
public bool Valor { get; set; }
public string Selecionado { get; set; }
}
My Razor is:
#model SYSTEMNAME.Models.EmprViewModel
<div class="container espaco">
#using (Html.BeginForm("SalvarAlteracao", "Empresas", FormMethod.Post, new { #id = "frmEmpresas" }))
{
#Html.HiddenFor(model => model.ID_EMP)
<div class="row">
#Html.EditorFor(m => Model.Telas)
</div>
}
And I created in ~\Shared\EditorTemplates\TelasViewModel.cshtml
#model SYSTEMNAME.Models.TelasViewModel
#Html.HiddenFor(m => m.ID_TELA)
#Html.HiddenFor(m => m.TITULO)
#Html.HiddenFor(m => m.Selecionado)
<div class="cols3-25"><label>#Model.TITULO: </label></div>
<div class="cols3-75">#Html.CheckBoxFor(m => m.Valor)</div>
The output code generated in Razor is fine, for each "Telas" Object I got something like this:
<input data-val="true" data-val-number="O campo ID_TELA deve ser um número." data-val-required="O campo ID_TELA é obrigatório." id="Telas_0__ID_TELA" name="Telas[0].ID_TELA" type="hidden" value="2">
<input id="Telas_0__TITULO" name="Telas[0].TITULO" type="hidden" value="Contatos">
<input id="Telas_0__Selecionado" name="Telas[0].Selecionado" type="hidden" value="">
<div class="cols3-25"><label>Contatos: </label></div>
<div class="cols3-75"><input data-val="true" data-val-required="O campo Valor é obrigatório." id="Telas_0__Valor" name="Telas[0].Valor" type="checkbox" value="true"><input name="Telas[0].Valor" type="hidden" value="false"></div>
But When I get the FormPost, the list comes "null"
[HttpPost]
public async Task<ActionResult> SalvarAlteracao(EmpresaViewModel EmpresaAlterado)
{
...
// Here if I try anything with EmpresaAlterado.Telas, it say "Telas is null";
}
What I'm maybe doing wrong or forgeting in this code?
Edit:
I the Post, there It's posting twice the field "Valor" like:
... &Telas%5B0%5D.ID_TELA=2&Telas%5B0%5D.TITULO=Contatos&Telas%5B0%5D.Selecionado=selected&Telas%5B0%5D.Valor=true&Telas%5B0%5D.Valor=false&Telas%5B1%5D.ID_TELA=3&Telas%5B1%5D.TITULO=Usuarios&Telas%5B1%5D.Selecionado=selected&Telas%5B1%5D.Valor=true&Telas%5B1%5D.Valor=false& ...
Can it have something to do With the two fields that "CheckboxFor" is creating on the Html? Here the example:
<div class="cols3-75"><input data-val="true" data-val-required="O campo Valor é obrigatório." id="Telas_0__Valor" name="Telas[0].Valor" type="checkbox" value="true"><input name="Telas[0].Valor" type="hidden" value="false"></div>
Only public properties are filled, check out that Telas it's a public variable, not property
Changing to
public List<TelasViewModel> Telas { get; set; }
will fix the issue

I'm trying to create a comment and like box like the one shown in this tutorial what are the main changes I need to make in order to make it work with ASP.NET Core 3.1
https://www.c-sharpcorner.com/blogs/how-to-create-a-comment-box-session-as-like-facebook-comment-in-asp-net
To create a Facebook-like comment box in ASP.NET Core， I do a demo to make it, referring to official documentation to configure database:https://learn.microsoft.com/en-us/aspnet/core/tutorials/first-mvc-app/adding-model?view=aspnetcore-5.0&tabs=visual-studio
1.To Create the comment box, we need to create User, Reply, Comment models to add some tables ,and add some ViewModels.
User.cs:
public class User
{
[Key]
public int Id { get; set; }
[Required]
public string UserName { get; set; }
[Required]
public string Password { get; set; }
[Required]
public string Email { get; set; }
public string ImageUrl { get; set; }
public DateTime? CreateOn { get; set; }
}
Reply.cs:
public class Reply
{
[Key]
public int Id { get; set; }
[Required]
public string Text { get; set; }
public DateTime? CreateOn { get; set; }
public int UserId { get; set; }
[ForeignKey("UserId")]
public virtual User User { get; set; }
public int CommentId { get; set; }
[ForeignKey("CommentId")]
public virtual Comment Comment{get;set;}
}
Comment.cs:
public class Comment
{
[Key]
public int Id { get; set; }
[Required]
public string Text { get; set; }
public DateTime? CreateOn { get; set; }
public int UserId { get; set; }
[ForeignKey("UserId")]
public virtual User User { get; set; }
public ICollection<Reply> Replies { get; set; }
public ICollection<User> Users { get; set; }
}
LoginVM.cs:
public class LoginVM
{
[Required]
[Key]
public string UserName { get; set; }
[Required]
public string Password { get; set; }
}
RegisterVM.cs:
public class RegisterVM
{
[Required]
public string UserName { get; set; }
[Required]
public string Password { get; set; }
[Compare("Password")]
public string ConfirmPassword { get; set; }
[Required]
public string Email { get; set; }
}
ReplyVM.cs:
public class ReplyVM
{
public string Reply { get; set; }
public int CID { get; set; }
}

4.Add codes in Startup.ConfigureServices:
public void ConfigureServices(IServiceCollection services)
{
services.AddSession();
services.AddControllersWithViews();
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("ApplicationDbContext")));
}
5.Add app.UseSession(); in Startup.Configure
6.Add a connection string to the appsettings.json file:
"ConnectionStrings": {
"ApplicationDbContext": "Server=(localdb)\\mssqllocaldb;Database=ApplicationDbContext-1;Trusted_Connection=True;MultipleActiveResultSets=true"}
7.In the Package Manager Console (PMC), enter the following commands separately:
Add-Migration InitialCreate
Update-Database
8.Add HomeController to set userId=0 when people first Login without register, add AccountController to manage user login or not, add ChatRoomController to manage user post comments or reply.
HomeController.cs:
public class HomeController : Controller
{ ....
public IActionResult Index()
{
ISession session = HttpContext.Session;
session.SetInt32("UserId", 0);
return View();
}
...
}
AccountController.cs:
public class AccountController : Controller
{
private readonly ApplicationDbContext db;
public AccountController(ApplicationDbContext context)
{
db = context;
}
//GET:Account/Register
[HttpGet]
public IActionResult Register()
{
return View();
}
//GET:Account/Register
[HttpPost]
public IActionResult Register(RegisterVM obj)
{
bool UserExistis=db.Users.Any(x=>x.UserName==obj.UserName);
if(UserExistis)
{
ViewBag.UserNameMessage = "This UserName is already in use, try another";
return View();
}
bool EmailExistis = db.Users.Any(y => y.Email == obj.Email);
if (EmailExistis)
{
ViewBag.EmailMessage = "This Email is already in use, try another";
return View();
}
//if username and email is unique, then we save or register the user
User u = new User();
u.UserName = obj.UserName;
u.Password = obj.Password;
u.Email = obj.Email;
u.ImageUrl = "";
u.CreateOn = DateTime.Now;
db.Users.Add(u);
db.SaveChanges();
return RedirectToAction("Index","ChatRoom");
}
//GET:Account/Login
[HttpGet]
public IActionResult Login()
{
return View();
}
//GET:Account/Login
[HttpPost]
public IActionResult Login(LoginVM obj)
{
bool existis = db.Users.Any(u => u.UserName == obj.UserName&&u.Password==obj.Password);
if(existis)
{
ISession session = HttpContext.Session;
session.SetInt32("UserId", db.Users.Single(x => x.UserName == obj.UserName).Id);
return RedirectToAction("Index","ChatRoom");
}
//if invalid credentials
ViewBag.Message = "Invalid Credentials!";
return View();
}
}
ChatRoomController.cs:
public class ChatRoomController: Controller
{
private readonly ApplicationDbContext db;
public ChatRoomController(ApplicationDbContext context)
{
db = context;
}
public IActionResult Index()
{
var comments = db.Comments.Include(x => x.Replies).ThenInclude(x=>x.User).OrderByDescending(x => x.CreateOn)
.ToList();
return View(comments);
}
//Post:ChatRoom/PostReply
[HttpPost]
public ActionResult PostReply(ReplyVM obj)
{
ISession session = HttpContext.Session;
int userId =(int)session.GetInt32("UserId");
if (userId==0)
{
return RedirectToAction("Login", "Account");
}
Reply r = new Reply();
r.Text = obj.Reply;
r.CommentId = obj.CID;
r.UserId =userId;
r.CreateOn = DateTime.Now;
db.Replies.Add(r);
db.SaveChanges();
return RedirectToAction("Index");
}
//Post:ChatRoom/PostComment
[HttpPost]
public ActionResult PostComment(string CommentText)
{
ISession session = HttpContext.Session;
int userId = (int)session.GetInt32("UserId");
if (userId == 0)
{
return RedirectToAction("Login", "Account");
}
Comment c = new Comment();
c.Text = CommentText;
c.CreateOn = DateTime.Now;
c.UserId = userId;
db.Comments.Add(c);
db.SaveChanges();
return RedirectToAction("Index");
}
}
9.Add views: Login.cshtml(for Login action in AccountController), Register.cshtml(for Register action in AccountController), index.cshtml(for Index action in ChatRoomController).

10.Add link in _Layout.cshtml.
<li class="nav-item">
<a class="nav-link text-dark" asp-area="" asp-controller="Account" asp-action="Register">Register</a>

I want to save values from a form to my database. I'm using a viewmodel with an selectlist property and a regular model. The value from the dropdown doesn't get saved. Despite being a trivial and seemingly pretty simple thing, I'm pretty lost.
Below my code:
Model:
public class Movie
{
public int MovieID { get; set; }
public string Name { get; set; }
public int StudioID { get; set; }
public Studio Studio { get; set; }
}
My ViewModel:
public class CreateMoviesViewModel
{
public Movie Movie { get; set; }
public IEnumerable<SelectListItem> StudiosSelectList { get; set; }
}
My Controller:
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create(CreateMoviesViewModel movieViewModel)
{
if (ModelState.IsValid)
{
_context.Add(movieViewModel);
await _context.SaveChangesAsync();
return RedirectToAction(nameof(Index));
}
movieViewModel.StudiosSelectList = new SelectList(_context.Studios.AsNoTracking(), "StudioID", "Name");
return View(movieViewModel);
And finally, my Form:
<form asp-action="Create">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<input type="hidden" asp-for="Movie.MovieID" />
<div class="form-group">
<label asp-for="Movie.Name" class="control-label"></label>
<input asp-for="Movie.Name" class="form-control" />
<span asp-validation-for="Movie.Name" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="Movie.StudioID" class="control-label"></label>
#Html.DropDownListFor(m => m.StudiosSelectList, Model.StudiosSelectList, "Select one")
</div>
<div class="form-group">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</form>
It is probably something wrong with my dropdown list, or with the logic described in the POST section. Any help is greatly appreciated!
You need to pass the selected dropdown value to your model:
public class CreateMoviesViewModel
{
public int SelectedValueId { get; set; } // <-- not sure what are you selecting, this could be MovieId if you are selecting a movie
public Movie Movie { get; set; }
public IEnumerable<SelectListItem> StudiosSelectList { get; set; }
}
Then you can use:
#Html.DropDownListFor(m => m.SelectedValueId, m.StudiosSelectList)
This way, the selected value Id would be passed to your model.
SelectValueId should be initialized to the default value that you want to display in the Dropdown.
I have been searching all over the internet about MVC many-to-many relationships (and have read every thing about it here too), but I can't seem to solve my problem.
I have a many-to-many relationship between a client and a standard service as seen below.
public class Client
{
public Client()
{
CustomServices = new HashSet<CustomService>();
StandardServices = new HashSet<StandardService>();
}
public int ClientID { get; set; }
public string Name { get; set; }
public Nullable<int> Users { get; set; }
public Nullable<bool> FH { get; set; }
public Nullable<bool> PH { get; set; }
public bool Hosted { get; set; }
public string ShortName { get; set; }
public Nullable<short> AttachmentLimit { get; set; }
public virtual ICollection<CustomService> CustomServices { get; set; }
public virtual ICollection<StandardService> StandardServices { get; set; }
And the standard service.
public class StandardService
{
public StandardService()
{
Clients = new HashSet<Client>();
}
public int StandardServiceID { get; set; }
public string StandardServiceName { get; set; }
public string LogOnAs { get; set; }
public int ServerID { get; set; }
public virtual Server Server { get; set; }
public virtual ICollection<Client> Clients { get; set; }
When creating a new client, I would like to be able to select from a list of check boxes for standard services that the client uses. I am able to get them to show up in the create view using the viewbag, but would like to be able to use a viewmodel.
I would also like to know how to get this to post with default model binding.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "ClientID,Name,Users,FH,Hosted,PH,ShortName,AttachmentLimit")] Client client)
{
if (ModelState.IsValid)
{
db.Clients.Add(client);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(client);
}
Here is the create method for the Client Controller.
public ActionResult Create()
{
ViewBag.StandardServices = db.StandardServices.ToList();
return View();
}
Part of my create view is below (that does the check boxes).
<div class="form-group">
#Html.LabelFor(model => model.StandardServices, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#foreach (var StandardService in ViewBag.StandardServices)
{
<div class="checkbox">
<input class="checkbox" type="checkbox" name="StandardServiceID" id="StandardServiceID" value="#StandardService.StandardServiceID"/>
#StandardService.StandardServiceName<br>
</div>
}
</div>
</div>
So how could I go about doing this? I have tried many things, but don't want to go though listing them all. None worked suffice it to say. Any help at all would be appreciated. I don't need the full solution, just some advice on where to go. Thanks!
Based on a comment below; and viewing the link provided, I think I have part of the solution. I just need to work on the post now. Here is what I have for the view model.
public class CreateClientVM
{
public CreateClientVM()
{
ClientStandardServices = new List<StandardService>();
}
public int ClientID { get; set; }
public string Name { get; set; }
public Nullable<int> Users { get; set; }
public Nullable<bool> FH { get; set; }
public Nullable<bool> PH { get; set; }
public bool Hosted { get; set; }
public string ShortName { get; set; }
public Nullable<short> AttachmentLimit { get; set; }
public List<StandardService> ClientStandardServices { get; set; }
public List<StandardServiceVM> StandardServices { get; set; }
}
public class StandardServiceVM
{
public int StandardServiceID { get; set; }
public string StandardServiceName { get; set; }
public bool IsSelected { get; set; }
}
And below is my Client Controller create method.
public ActionResult Create()
{
//ViewBag.StandardServices = db.StandardServices.ToList();
CreateClientVM clientVM = new CreateClientVM();
var ListVM = new List<StandardServiceVM>();
var standardServices = db.StandardServices.ToList();
foreach(var s in standardServices)
{
var viewModel = new StandardServiceVM
{
StandardServiceID = s.StandardServiceID,
StandardServiceName = s.StandardServiceName,
IsSelected = false
};
ListVM.Add(viewModel);
}
clientVM.StandardServices = ListVM;
return View(clientVM);
}
And finally part of my create view.
<div class="form-group">
#Html.HiddenFor(m => m.ClientID)
#Html.LabelFor(m => m.StandardServices, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#for (int i = 0; i < Model.StandardServices.Count; i++)
{
<div class="checkbox">
#Html.HiddenFor(m => m.StandardServices[i].StandardServiceID)
#Html.CheckBoxFor(m => m.StandardServices[i].IsSelected)
#Html.LabelFor(m => m.StandardServices[i].IsSelected, Model.StandardServices[i].StandardServiceName)
</div>
}
</div>
</div>
Here is the html that gets rendered when viewing the page source. I think this looks right, but I'm not entirely sure.
<div class="form-group">
<input data-val="true" data-val-number="The field ClientID must be a number." data-val-required="The ClientID field is required." id="ClientID" name="ClientID" type="hidden" value="0" />

<input data-val="true" data-val-required="The IsSelected field is required." id="StandardServices_0__IsSelected" name="StandardServices[0].IsSelected" type="checkbox" value="true" />
<input name="StandardServices[0].IsSelected" type="hidden" value="false" />
<label for="StandardServices_0__IsSelected">FHEmailService</label>
</div>
<div class="checkbox">
<input data-val="true" data-val-number="The field StandardServiceID must be a number." data-val-required="The StandardServiceID field is required." id="StandardServices_1__StandardServiceID" name="StandardServices[1].StandardServiceID" type="hidden" value="2" />
<input data-val="true" data-val-required="The IsSelected field is required." id="StandardServices_1__IsSelected" name="StandardServices[1].IsSelected" type="checkbox" value="true" />
<input name="StandardServices[1].IsSelected" type="hidden" value="false" />
<label for="StandardServices_1__IsSelected">FHScheduledReports</label>
</div>
</div>
</div>
Can anyone comment if this looks okay? I believe it does. Now I just need to figure out how to post it.
I have a view with a number of checkboxes in it. I want to be able to pass the values of the checkboxes to the controller, then output a list of the OfficeNames that have been ticked. I am not sure how to pass the values of multiple checkboxes back to the controller, or how to output the OfficeNames based on which boxes have been ticked

{
<label>#Html.DisplayFor(modelItem => item.OfficeName)</label>
<input type="checkbox" name="bettingOfficeIDs" value="#item.BettingOfficeID">
}
</p>
And in your Action you can get the selected office ids in bettingOfficeIDs variable:
public ActionResult YourActionName(int[] bettingOfficeIDs)
Few things that need to change here.
If you want values to be passed to action method they need to be within form not outside
For MVT to 'understand' checkbox values as array (or more complex object) you need to work with their html name attribute.
I will do demonstration application below that should help you understand how it works:
CsHtml: Notice that you need to add value attribute to checkboxes to be able to read their values, checkbox gets true only when checkbox is ticked and value is true, hence the javascript. You can add as many of complex object properties as hidden fields as long as you give them names that match to the object property names in viewModel. In this case I am only passing BettingOfficeID
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
$(document).on("click", "[type='checkbox']", function(e) {
if (this.checked) {
$(this).attr("value", "true");
} else {
$(this).attr("value","false");}
});
<p>
#using (Html.BeginForm())
{
<p>
Start Date: #Html.TextBox("StartDate") <br />
<br />
End Date: #Html.TextBox("EndDate") <br />
<br />
</p>
<p>
<input type="checkbox" name="BettingOffices[0].Selected" value="true">
<input type="hidden" name="BettingOffices[0].BettingOfficeID" value="1">
<input type="checkbox" name="BettingOffices[1].Selected" value="false">
<input type="hidden" name="BettingOffices[1].BettingOfficeID" value="2">
<input type="checkbox" name="BettingOffices[2].Selected" value="true">
<input type="hidden" name="BettingOffices[2].BettingOfficeID" value="3">

<input type="checkbox" name="BettingOffices[4].Selected" value="true">
<input type="hidden" name="BettingOffices[4].BettingOfficeID" value="5">
</p>
<input type="submit" value="submit"/>
}
Post Action method to add to controller
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(BettingViewModel viewModel)
{
return null;
}
BettingViewModel: I have added Selected property to BettingOffice class.
public class BettingViewModel
{
public string StartDate { get; set; }
public string EndDate { get; set; }
public List<BettingOffice> BettingOffices { get; set; }
}
public class BettingOffice

public Nullable<bool> SupportOnly { get; set; }
public Nullable<int> SisSrNumer { get; set; }
public Nullable<bool> Local { get; set; }
public string Server { get; set; }
}
Hope this saves you some time.

1. First of all, you are generating checkboxes with same name. So how you will be able to retrieve them on server end separately?
So declare some counter that gets incremented and name checkboxes uniquely.
#foreach (var item in Model.BettingOffices)
{
int counter=1;
var checkboxName = "selectedShops" + counter;
<label>#Html.DisplayFor(modelItem => item.OfficeName)</label>
<input type="checkbox" name="#checkboxName" value="#item.OfficeName">
counter++;
}
2. Now on submission of Form in your controller, get checkboxes as -
//Loop through the request.forms
for (var i = 0; i <= Request.Form.Count; i++)
{
var checkboxValue = Request.Form["selectedShops[" + i + "]"];
// Do whatever you want to with this checkbox value
}
For ticked values, you will probably get True value. Debug the retrieved value to write further code accordingly.
Try the following
your View is:
#foreach (var item in Model.BettingOffices)
{
<label>#Html.DisplayFor(modelItem => item.OfficeName)</label>
<input type="checkbox" name="selectedShops" value="#item.OfficeName">
}
Controller
[HttpPost]
public ActionResult Index(FormCollection collection)
{
if(!string.IsNullOrEmpty(collection["selectedShops"]))
{
string strSelectedShops = collection["selectedShops"];
}
}
Hi you can get the selected checkbox value using the bellow code it seem working fine fore me,
<script>
$(document).ready(function()
{
$("input[type=checkbox]").click(function()
{
var categoryVals = [];
categoryVals.push('');
$('#Category_category :checked').each(function() {
categoryVals.push($(this).val());
});
$.ajax({
type:"POST",
url:"<?php echo $this->createUrl('ads/searchresult'); ?>", //url of the action page
data:{'category': categoryVals},
success : function(response){
//code to do somethng if its success
}
});
}
}
</script>
This is a continuation of this question Model class and Mapping
I had my Client class now working fine and it's defined as

I mapped column names using Fluent API and I also re-defined my original "repository" classes to be very similar to defined in this tutorial http://code.msdn.microsoft.com/ASPNET-MVC-Application-b01a9fe8
This is my current partial view for the client form called _ClientForm:
#using WebDemo.Helper
#model CardNumbers.Objects.Client
<fieldset>
<legend>Client Info</legend>
#Html.ValidationSummary(true)
<input type="hidden" id="fntype" name="fntype">
#Html.HiddenFor(model => model.Id)
#Html.EditorFor(model => model.Number, EditorTemplate.TextBox)
#Html.EditorFor(model => model.Name, EditorTemplate.TextBox)
#Html.EditorFor(model => model.Address, EditorTemplate.EditBox)
<div id="ContactsInfo">
#*Contact 1*#
<div id="Contact1">
#*#Html.EditorFor(model=>model.Contact1)*#
#Html.EditorFor(model=>model.Contact1.Contact, EditorTemplate.TextBox)
#Html.EditorFor(model=>model.Contact1.Email, EditorTemplate.TextBox)
</div>
#*Contact2*#
<div id="Contact2">
#* #Html.EditorFor(model => model.Contact2)*#
</div>
</div>
#*<div class="clear"></div>*#
<div id="SaveCancel" class="float-right">
<button type="Submit" id="btnSave">Save</button>
<button type="reset" id="btnCancel">Cancel</button>
</div>
</fieldset>
I already tried to revert to original way of only one level and I also commented the second Contact2 info but still the e-mail validation doesn't work and all other validations also don't seem to work.
The EditorFor textboxes are defined based on this blog post http://fusionovation.com/post/2010/02/15/adding-a-rich-text-editor-to-asp-net-mvc-using-strongly-typed-helpers-dataannotations-amp-jquery.aspx
And these are two of the new EditorFor I added:
PhoneInfo.cshtml
#using WebDemo.Helper
#model CardNumbers.Objects.PhoneInfo
<div id="PhoneInfo">
<div class="float-left">
#Html.EditorFor(model => model.Phone, EditorTemplate.TextBox)
</div>
<div class="float-right">
#Html.EditorFor(model => model.Ext, EditorTemplate.TextBox)
</div>
</div>
And ContactDetail.cshtml
#using WebDemo.Helper
#model CardNumbers.Objects.ContactDetail
#Html.EditorFor(model => model.Contact, EditorTemplate.TextBox)
#Html.EditorFor(model => model.Email, EditorTemplate.TextBox)
#Html.EditorFor(model=>model.phoneInfo)
So, as you can see, the code of the views is now very compact.
However, with all of these in place the validations don't see to fire anymore. I used to test validation on EMail by typing some garbage. It used to provide a validation message near the textbox. Now I observe that the email textbox takes the red border, but there is no message.
Do you see what I am missing now and if it's possible to use complex type and validations?
To clarify, the _ClientForm is called from this Client view:
#model CardNumbers.Objects.Client
#{
ViewBag.Title = "Client";
}
#section scripts {
<script src="#Url.Content("~/Scripts/Clients.js")" type="text/javascript" ></script>
}
<form id="frmClientsSearch">
<label for="clientNo">Client No: </label>
<input type="number" name="searchClientNo" class="numericOnly" /><br />
<label for="clientName">Client Name: </label>
<input type = "text" size =25 value ="Please enter the search value" class="SelectOnEntry"
name ="searchClientName" />
<input type="button" id="btnClientsSearch" value ="Find / Refresh" />
</form>
<div style="padding-left: 150px; padding-top: 50px; padding-bottom: 50px;" id="ClientsResults">
<table id="flexClients" style="display: none">
</table>
</div>
<div style="display: none">
<form id="sform" title="Client Info">
#{Html.RenderPartial("_ClientForm", Model) ;}
</form>
</div>
Thanks.
I don't see a form anywhere on your page. A form context is required for validation to work. You need to wrap the Editor attributes in BeginForm block.
After some trials and error I found that the TextBox EditorFor view was the culprit. I documented what I found in my answer here http://forums.asp.net/t/1855963.aspx/1?Validation+messages+don+t+show+up+what+is+missing+
Basically, as long as I use this EditorFor
#*#using WebDemo.Helper*#
#model CardNumbers.Objects.PhoneInfo
<div id="PhoneInfo">
<div class="float-left">
#* #Html.EditorFor(model => model.Phone, EditorTemplate.TextBox)*#
<div class="editor-label">
#Html.LabelFor(model => model.Phone)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Phone)
#Html.ValidationMessageFor(model => model.Phone)
</div>
</div>
<div class="float-right">
#*#Html.EditorFor(model => model.Ext, EditorTemplate.TextBox)*#
<div class="editor-label">
#Html.LabelFor(model => model.Ext)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Ext)
#Html.ValidationMessageFor(model => model.Ext)
</div>
</div>
</div>
All seems to work OK. But if I try to switch to a shorter syntax and use this EditorFor for the textbox:
<div class="editor-label">
#Html.Label((ViewData.ModelMetadata.DisplayName??ViewData.ModelMetadata.PropertyName),
new Dictionary<string, object>
{
{ "for", ViewData.ModelMetadata.PropertyName }
})
</div>
<div class="editor-field">
#Html.TextBox("", (object)Model,
new Dictionary<string, object>
{
{ "id", ViewData.ModelMetadata.PropertyName },
{ "name", ViewData.ModelMetadata.PropertyName },
{ "class", "text-box single-line"},
{ "data-bind", "value: " + ViewData.ModelMetadata.PropertyName },
})
#Html.ValidationMessage(ViewData.ModelMetadata.PropertyName,
new Dictionary<string, object>
{
{ "data-valmsg-for", ViewData.ModelMetadata.PropertyName }
})
</div>
Validation messages do not show anymore.
Hopefully this answer will help someone or you may see what I am missing here.
