I am passing form collection so my firstname and lastname are not wiped out. Please suggest how can i persist my values.
[HttpPost]
public ActionResult Index(FormCollection dataColl)
{
ColComments datgrp = new ColComments();
datgrp.fname = dataColl[0].ToString();
datgrp.lname = dataColl[1].ToString();
if (!this.IsCaptchaValid(""))
{
ViewBag.Classname = "alert alert-warning";
ViewBag.ErrorMessage = "Incorrect captcha answer.";
}
else
{
ViewBag.ErrorMessage = "OKAY";
return RedirectToAction("Landing", "Account");
}
return View(dataColl);
}
Index view.
#using CaptchaMvc.HtmlHelpers
#model CaptchaTestApp.Models.ColComments
#{
ViewBag.Title = "Home Page";
}
<div class="jumbotron">

You need to return the same view which you are sending in HttpGet method with updated values. You are sending form collection object to view.
[HttpPost]
public ActionResult Index(FormCollection dataColl)
{
ColComments datgrp = new ColComments();
datgrp.fname = dataColl[0].ToString();
datgrp.lname = dataColl[1].ToString();
if (!this.IsCaptchaValid(""))
{
ViewBag.Classname = "alert alert-warning";
ViewBag.ErrorMessage = "Incorrect captcha answer.";
}
else
{
ViewBag.ErrorMessage = "OKAY";
return RedirectToAction("Index", "Home");
}
return View(datgrp);
}
I have created a form for add comment. I have created it in main View called Index in Home controller. bellow is Index View
private projectDBEntities db = new projectDBEntities();
public ActionResult Index()
{
ViewBag.Message = "Modify this template to jump-start your ASP.NET MVC application.";
return View();
}

return PartialView("_Comment");
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult AddComment(comment cmt)
{
if (ModelState.IsValid)
{
db.comments.Add(cmt);
db.SaveChanges();
return RedirectToAction("Index", "Home");
}
return PartialView("_Comment", cmt);
}
below is _Comment Partial View
#using (Html.BeginForm()) {#Html.AntiForgeryToken()#Html.ValidationSummary(true)
<fieldset>
<legend>comment</legend>
<div class="editor-label">
#Html.LabelFor(model => model.cmd_content)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.cmd_content)
#Html.ValidationMessageFor(model => model.cmd_content)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.t_email)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.t_email)
#Html.ValidationMessageFor(model => model.t_email)
</div>
<p>
<input type="submit" value="Comment" />
</p>
</fieldset>}
System.Web.HttpException was occuerd. I want to know What is the reason behind this error and what is the best method to form submit using partail View.
Id have to agree with Sandip's answer here, but to elaborate ..
#using (Html.BeginForm("AddComment", "Home"))
{
//Content to send to the server-side
}
As long as your model in your partial view points to your 'Comment' object, then this should work fine when using #Html.EditorFor(). In your controller, your already waiting for your 'Comment' object to be populated. So on Post, when the submit is clicked, it will populate that object.
Hope this helps.
#using (Html.BeginForm("AddComment", "Home"))

I have a custom class
public class BloggerViewModel
{
public Person Blogger;
public List<BloggerWebsite> BloggerWebsites;
}
That I pass into a view
[HttpGet]
public ActionResult Edit(int id)
{
blogger = GetById(id);
var WebSites = GetBloggersWebsites(Id);
var BloggerViewModel = new BloggerViewModel();
BloggerViewModel.Blogger = blogger;
BloggerViewModel.BloggerWebsites = WebSites;
return View(BloggerViewModel);
}
Then when I post back to the edit action
[HttpPost]
public ActionResult Edit(BloggerViewModel entity)
{
return View(entity);
}
entity is null.
My view is something like this ( I took out allot of the code that you didn't need to see. Such as most of the text box bindings)
#model Bloginect.Model.Models.BloggerViewModel
<h2>Edit</h2>
#using (Html.BeginForm()) {
#Html.ValidationSummary(true)
<fieldset>
<legend>Person</legend>
#Html.HiddenFor(model => model.Blogger.Id)
<div class="editor-label">
#Html.LabelFor(model => model.Blogger.FirstName)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Blogger.FirstName)
#Html.ValidationMessageFor(model => model.Blogger.FirstName)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.Blogger.LastName)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Blogger.LastName)
#Html.ValidationMessageFor(model => model.Blogger.LastName)
</div>
<div class="editor-field">
#if (Model.BloggerWebsites[0].Website != null)
{
Html.EditorFor(model => model.BloggerWebsites[0].Website);
}
else
{
#Html.TextBox("Website1")
}
</div>
<div class="editor-field">
#if (Model.BloggerWebsites[1].Website != null)
{
Html.EditorFor(model => model.BloggerWebsites[0].Website);
}
else
{
#Html.TextBox("Website2")
}
</div>
<div class="editor-field">
#if (Model.BloggerWebsites[2].Website != null)
{
Html.EditorFor(model => model.BloggerWebsites[0].Website);
}
else
{
#Html.TextBox("Website3")
}
</div>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
}
<div>
#Html.ActionLink("Back to List", "Index")
</div>
Is there something I am doing wrong? I have checked out some of the other replies to similar questions on this and they did not answer my question.
You must use editors to handle the bindings to your nested model properties, a good example on how to do it can be found here.
I'm completely new to MVC having made the decision to try make the switch from aspx WebForms.
I have created a view using the MVC view creator wizard and selected a strongly typed class and an edit Scaffold template.
I got the following
#using (Html.BeginForm()) {
#Html.ValidationSummary(true)
<fieldset>
<legend>Company</legend>
#Html.HiddenFor(model => model.Id)
<div class="editor-label">
#Html.LabelFor(model => model.Name)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Name)
#Html.ValidationMessageFor(model => model.Name)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.PhoneNumber)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.PhoneNumber)
#Html.ValidationMessageFor(model => model.PhoneNumber)
</div>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
}
In the Controller I have the following to get the model details
[System.Web.Http.HttpGet]
public ActionResult Edit(int id)
{
var uow = new BlogUow();
var company = uow.Companies.GetById(id);
return View(company);
}
This works fine but the problem is, I'm stumped on how I actually save the newly entered details.
I relied too much on how the web forms handle post backs.
You must write a post action for your edit in the controller:
[System.Web.Http.HttpPost]
public ActionResult Edit(Companies company)
{
var uow = new BlogUow();
if (ModelState.IsValid)
{
uow.Entry(company).State = EntityState.Modified;
return RedirectToAction("Index");
}
return View(company);
}
note Companies overload
[HttpPost]
public ActionResult Edit(Companies company)
{
var uow = new BlogUow();
if (ModelState.IsValid)
{
Edit here
}
return View(company);
}
Hi I am working in a MVC 3 application. I have a Create Form with following code.
#model Xrm.Student
#{
ViewBag.Title = "Create Student Record";
}
#using (Html.BeginForm("Create", "Student", FormMethod.Post))
{
<div class="editor-label">
#Html.LabelFor(model => #Model.FirstName)
</div>
<div class="editor-field">
#Html.EditorFor(model => #Model.FirstName)
#Html.ValidationMessageFor(model => #Model.FirstName)
</div>
<div>
<input id="Submit1" type="submit" value="Submit" />
</div>
}
I want to add a new drop down under Firsname field which should be populated with pubjects. Subject is different Entity. I could be very easy, but I am newbie with MVC so I just stuck here. Can anyone please suggest me the way to achieve it.
Thanks and Regards
I would define a view model:
public class MyViewModel
{
public Student Student { get; set; }
[DisplayName("Subject")]
[Required]
public string SubjectId { get; set; }
public IEnumerable<Subject> Subjects { get; set; }
}
and then have your controller populate and pass this view model to the view:
public ActionResult Create()
{
var model = new MyViewModel();
model.Student = new Student();
model.Subjects = db.Subjects;
return View(model);
}
and finally have your view strongly typed to the view model:
#model MyViewModel
#{
ViewBag.Title = "Create Student Record";
}
#using (Html.BeginForm())
{
<div class="editor-label">
#Html.LabelFor(x => x.Student.FirstName)
</div>
<div class="editor-field">
#Html.EditorFor(x => x.Student.FirstName)
#Html.ValidationMessageFor(x => x.Student.FirstName)
</div>
<div class="editor-label">
#Html.LabelFor(x => x.SubjectId)
</div>
<div class="editor-field">
#Html.DropDownListFor(
x => x.SubjectId,
new SelectList(Model.Subjects, "Id", "Name"),
"-- Subject --"
)
#Html.ValidationMessageFor(x => x.SubjectId)
</div>
<div>
<input type="submit" value="Submit" />
</div>
}
The "Id" and "Name" values I used for the SelectList must obviously be existing properties on your Subject class that you want to be used as respectively binding the id and the text of each option of the dropdown.
