Can any one suggest text areas field validation in asp.net mvc.I tried many ways but no luck
My View for text area:
#Html.TextAreaFor(m => m.EmailTemplate, new { rows = "10", cols = "150", #class = "form-control", #id = "Email", required = "required", #maxlength = "10000" })
#Html.ValidationMessagefor(m => m.EmailTemplate, new { #class = "text-danger"});
#Html.ValidationMessage("CustomError", new { #class = "text-danger" })
My Model:
[AllowHtml]
[Required(ErrorMessage ="Email Template is required")]
public string EmailTemplate { get; set; }
Change
#Html.ValidationMessagefor(m => m.EmailTemplate, new { #class = "text-danger"});
To
#Html.ValidationMessageFor(m => m.EmailTemplate, null, new { #class = "text-danger"})
As the second parameter of #Html.ValidationMessageFor takes optional validation message (use null or ""), and the third parameter takes the htmlAttributes #class etc.
For TextAreaFor Validation in Model, I have applied "[DataType(DataType.MultilineText)]" attribute to make it work.
Model
public class DemoModel
{
[Required(ErrorMessage = "Required")]
[AllowHtml]
[DataType(DataType.MultilineText)]
public string EmailTemplate { get; set; }
}
View
#model WebRedis.Models.DemoModel
#{
Layout = null;
}
<link href="~/Content/bootstrap.css" rel="stylesheet" />
<script src="~/Scripts/jquery-1.10.2.min.js"></script>

I have below editorfor which is multiline, I need to auto adjust height when user starts adding multiple email address in separate lines using bootstrap. Any code example is highly appreciated.
Model:
[DataType(DataType.MultilineText)]
public string AdditionalEmailAddressesText { get; set; }
View:
<div class="form-group">
#Html.LabelFor(m => m.AdditionalEmailAddressesText, new { #class = "col-sm-2 control-label" })
<div class="col-sm-10">
#Html.EditorFor(m => m.AdditionalEmailAddressesText, new { htmlAttributes = new { #class = "form-control", placeholder = #Strings.Porting_AdditionalEmailAddressesSubtext } })
#Html.ValidationMessageFor(m => m.AdditionalEmailAddressesText)
</div>
</div>
For textarea tag, there's no auto-height attribute to make it adjust the height automatically. And for the [DataType(DataType.MultilineText)] annotation, it doesn't provide feature for setting rows and colums as well. So you have to write script code to add oninput event listener to change the style.
#model NewEvent
<h1>#ViewData["Title"]</h1>
<p>Use this page to detail your site's privacy policy.</p>
<div class="form-group">
#Html.LabelFor(m => m.Body, new { #class = "col-sm-2 control-label" })
<div class="col-sm-10">
#Html.EditorFor(m => m.Body, new { htmlAttributes = new { #class = "form-control", placeholder = "placeholder" } })
#Html.TextAreaFor(model => model.Body, new {cols = 2, rows = 5})
#Html.ValidationMessageFor(m => m.Body)
</div>
</div>
#section scripts {
<script>
$("#Body").each(function () {
this.setAttribute("style", "height:" + (this.scrollHeight) + "px;overflow-y:hidden;");
}).on("input", function () {
this.style.height = "auto";
this.style.height = (this.scrollHeight) + "px";
});
</script>
}
I am Creating View Model of Employee Class and strongly typed my Create View with the EmployeeViewModel. In future, I will add many classes in my View Model. But the problem is I am getting Gender Foreign Key Error. May be I am binding wrong values in Create Controller. Below is my code:
Create Controllers:
public ActionResult Create()
{
ViewBag.GenderId = new SelectList(db.Genders, "Id", "Name");
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(EmployeeViewModel employeeModel)
{
if (ModelState.IsValid)
{
db.Employees.Add(employeeModel.Employee);
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.GenderId = new SelectList(db.Genders, "Id", "Name", employeeModel.Employee.GenderId);
return View(employeeModel);
}
Create View:
#model WebApplication2.EmployeeViewModel
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Employee</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.Employee.Name, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Employee.Name, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Employee.Name, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Employee.GenderId, "GenderId", htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownList("GenderId", null, htmlAttributes: new { #class = "form-control" })
#Html.ValidationMessageFor(model => model.Employee.GenderId, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</div>
</div>
}
Models:
public class Employee

public string Name { get; set; }
public byte GenderId { get; set; }
public Gender Gender { get; set; }
}
public class Gender {

I am trying to create a new employee in MVC 5. I used CRUD to generate views and models. I edited a few lines of code and I get this error:
Cannot insert explicit value for identity column in table 'Table' when IDENTITY_INSERT is set to OFF.
Where I got this:
public ActionResult Create([Bind(Include = "Imie,Nazwisko,Pesel,Data_zatrudnienia,Data_zwolnienia,Pensja,Wyksztalcenie")] Osoba osoba,Pracownik pracownik)
{
if (ModelState.IsValid)
{
db.Osoba.Add(osoba);
db.Pracownik.Add(pracownik);
db.SaveChanges();
return RedirectToAction("Index");
}
My model class:
public partial class Pracownik
{

'Pracownik' class is employee and he is inherits from 'Osoba' which is Person in English. I dont know where I trying to put this id in my code.
You are trying to save an object to the database with an explicit ID set by you while the database is expecting to generate that value itself. That is the Id_osoby property in your object is set to something other than 0 and it is not identified to the EF framework as an identity field. If you want the Id to be generated by the database as your post suggests, then the corresponding property in the Object should be decorated with the [Key] attribute.
I have a single page with multiple partials set up. I want to be able to validate and update each partial seperatly. The validation works BUT when I type in a correct value and press save the page goes to the partial view instead of staying on the single page. What am I doing wrong here?
This is my main page :
#for (var i = 0; i < 10; i++)
{
var idTest = "Test_" + i;
<div id="#idTest">
#Html.Action("Detail", new { id = i })
</div>
}
The partial is created like this:
#{
var idTest = "Test_" + Model.Id;
var ajaxOptions = new AjaxOptions
{
UpdateTargetId = #idTest,
HttpMethod = "POST",
InsertionMode = InsertionMode.Replace
};}
#using (Ajax.BeginForm("Detail", ajaxOptions))
{ #Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Test</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.Gemeente, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.TextBoxFor(model => model.Gemeente, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Gemeente, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Save" class="btn btn-default" />
</div>
</div>
</div>
}
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
}
This is the simple model:
public class Test
{
public int Id { get; set; }
[Required(ErrorMessage = "Gelieve een gemeente op te geven")]
public string Gemeente { get; set; }
}
These are the actions:
[HttpGet]
public ActionResult Detail(int id)
{
Models.Test model = new Models.Test();
model.Id = id;
return View(model);
}
[HttpPost]
public ActionResult Detail(Models.Test model)
{
if(ModelState.IsValid)
{
return PartialView(model);
}
return PartialView(model);
}
Add these lines to your view and also use #Html.Partial as shown below
<script src="~/Scripts/jquery-1.8.2.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
so that your main view is
<script src="~/Scripts/jquery-1.8.2.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
#for (var i = 0; i < 10; i++)
{
var idTest = "Test_" + i;
<div id="#idTest">
#Html.Partial("Detail", new Test { Id = i })}
</div>
}
Scripts would be for unobtrusive ajax so that your ajax button works and Html.Partial so that first time when you load your page in foreach only partial view is rendered (not the full view)
I am in trouble with a posted file related to an entity, I can see the posted file in the request, but if I add the httppostedfile as action parameter it will be null... what should I do to manage this case?
NewsArticle model:
public class NewsArticle
{
public string Title{get; set;}
public int ID{get; set;}
[AllowHtml]
public string Body { get; set; }
public Image Image { get; set; }
//other stuff
}
where the field Image is:
the related entity will be created in the newarticlecontroller
public class Image
{
public int ID { get; set; }
public string URL { get; set; }
public string Title { get; set; }
public string Subtitle { get; set; }

newsArticle.Body = newsArticle.Body;
_repository.Add(newsArticle);
return RedirectToAction("Index");
}
return View(newsArticle);
}
Any help will be really appreciated
And what if you put input file in your form like:
<div class="form-group">
<label for="newsimage">Select news image:</label>
<div class="col-md-10">
<div class="checkbox">
<input id="newsimage" type="file" name="newsimage"/>
</div>
</div>
</div>
and post action will be:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "ID,Title,Body,SubTitle,Published,Image")]NewsArticle newsArticle )// here I don't know how to manage the posted file
{
if (ModelState.IsValid)
{
string ImageUrl="";
for (int i = 0; i < Request.Files.Count; i++)
{
if (Request.Files[i].FileName!="")
{
string UrlFile = Server.MapPath("~/newsimagefolderpath/") + FileName;
Request.Files[i].SaveAs(UrlFile);
ImageUrl = UrlFile;
}
}
newsArticle.Date = DateTime.Now;
newsArticle.URL = string.IsNullOrEmpty(ImageUrl) ? "defaultimagepath" : ImageUrl;
newsArticle.AuthorID = User.Identity.GetUserId();
newsArticle.Body = newsArticle.Body;
_repository.Add(newsArticle);
return RedirectToAction("Index");
}
return View(newsArticle);
}
Ok, I am new to MVC so obviously I have to pay the tax, btw this is what I have done to solve this problem:
I have created a ViewModel to host the aggregated data of the view:
public class NewsArticleViewModel
{
public string Title { get; set; }
public int ID { get; set; }
[AllowHtml]
public string Body { get; set; }
public string SubTitle { get; set; }
public string AuthorID { get; set; }
public DateTime Date { get; set; }
public bool Published { get; set; }
public HttpPostedFileBase ImageUpload { get; set; }
}
then I have changed the signature of the control action:
[Authorize]
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "Title,Body,SubTitle,Published,ImageUpload")]GatorsWebSite.ViewModels.NewsArticleViewModel newsArticle)
then I have corrected a typo in the form declaration :)
#using (Html.BeginForm("Create", "NewsArticles", FormMethod.Post, new { enctype = "multipart/form-data" }))
...and then I have changed the view
#Html.LabelFor(model => model.ImageUpload, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.TextBoxFor(m => m.ImageUpload, new { type = "file" })
#Html.ValidationMessageFor(m => m.ImageUpload)
</div>
Result:
