I am beginner in asp.net mvc . I am going to connect an action of button in view.
but i cant. i work with web form, in fact i want to click on the button, create action will be called and insert the data.
my code is as following:
The Controller:
namespace BookStore.Controllers
{
public class BookController : Controller
{
public ActionResult Create()
{
return View();
}
[HttpPost]
public ActionResult Create(book bookobj)
{
var dBook=new DBook();
dBook.Insertbook(bookobj);
return RedirectToAction("Index", "Home");
}
}
}
The View:
#model BookStore.Models.DomainObject.book
#{
ViewBag.Title = "Create";
}
<h2>insert data/h2>
#using(Html.BeginForm())
{
#Html.ValidationSummary(true);
<fieldset>
<div>
#Html.LabelFor(model=> model.book_name)
</div>
<div>
#Html.EditorFor(model => model.book_name)
</div>
<div>
#Html.LabelFor(model=>model.book_qty)
</div>
<div>
#Html.EditorFor(model=>model.book_qty)
</div>
<br/>
<div>
<input id="Button_craete_book" type="button" value="insert" />
</div>
</fieldset>
}
Change the button type to "submit":
<input id="Button_craete_book" type="submit" value="insert" />
That will post the form and values to the Edit method in the controller, as marked with the HttpPost attribute.

So, i started learning MVC, and i need to pass an email to a controller. (Trying to make a standard email signup)
Therefore i have an input and a button which (should) pass the input to an argument accepting controller and then redirect to another view.
I have the following controllers:
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(string mail)
{
person = new EmailSignup{Email = mail};
return RedirectToAction("details");
}
public ActionResult details()
{
return View(person);
}
This is what i have in my View:
#using (Html.BeginForm("Index", "Home", FormMethod.Post))
{
<form class="col-md-12">
<div class="form-group form-inline">
<label class="margin20">Sign up for newsletter</label>
<input type="Email" class="form-control" style="display:inline-block; max-width:200px" id="mail" placeholder="Example#Example.com" />
<button type="submit" class="btn btn-default" style="display:inline-block" id="emailSignup">Signup</button>
</div>
</form>
}
It redirects to my "details" view, but my email is not showing.
Furthermore, is this best practice? would i want to do it like this?
#using (Html.BeginForm("Index", "Home", FormMethod.Post)) renders a form, you don't need a second one inside it (if you need to add the class, you can use an overload of Html.BeginForm). Your input contains an id property, but not a name property. name is what's used when an action happens inside a form.
I'm new to developing web applications and most importantly new to mvc. I'm trying to navigate from one view to another controller action including parameters. I have the below code in my currently displaying view:
<p>
<a asp-controller="Working_set" asp-action="Create">Create new Working set</a>
</p>
#foreach (var item in Model)
{
<div class="col-sm-6 col-md-3">
<div class="thumbnail tile tile-medium">
<a asp-controller="SelectedWorking_set" asp-action="index">
<h2>
#Html.DisplayFor(modelItem => item.Name)
<input name="workingSetID" type="hidden" value="#item.Working_setID" />
</h2>
</a>
</div>
</div>
}
How can i use the Working_setID in the controller SelectedWorking_set below:
[Route("SelectedWorking_set")]
public class SelectedWorking_setController: Controller
{
private FlightmapContext _context;
public SelectedWorking_setController(FlightmapContext context)
{
_context = context;
}
public IActionResult Index()
{
return View();
}
[HttpPost("Index")]
public IActionResult Index([FromBody]int workingSetID)
{
//return View(_context.Project.ToList());
return View();
}
}
You need to pass input name to your controller method like below example;
<input name="workingSetID" type="hidden" value="#item.Working_setID" />
here "workingSetID" name we need to pass your controller method, Suppose your method name is "Index" then you need to write like this in your controller.
[HttpPost]
public ActionResult Index(string workingSetID)
{
//Code here
}
like this you will get "Working_setID" value in your controller method. And also you need submit button to post this value to controller.
I know the title of this question isn't very pretty. I dint have a better way to put it.
Lets look at the following code :
View for delete action:
#model LearningMVC.Models.Blog
#{
ViewBag.Title = "Delete";
}
<h2>Delete</h2>
<h3>Are you sure you want to delete this?</h3>
<fieldset>
<legend>Blog</legend>
<div class="display-label">
#Html.DisplayNameFor(model => model.URL)
</div>
<div class="display-field">
#Html.DisplayFor(model => model.URL)
</div>
</fieldset>
#using (Html.BeginForm()) {
<p>
<input type="submit" value="Delete" /> |
#Html.ActionLink("Back to List", "Index")
</p>
}
Controller action for delete action
[HttpPost, ActionName("Delete")]
public ActionResult DeleteConfirmed(int id)
{
Blog blog = db.Blogs.Find(id);
db.Blogs.Remove(blog);
db.SaveChanges();
return RedirectToAction("Index");
}
My questions is, How on earth this method got its parameter ?!
I'm new to Asp.net MVC.
I have an application that manages users. My problem is that when I click on a delete link of a user row, the delete method has [AcceptVerbs(HttpVerbs.Post)] annotation is called automatically after a render delete method invoked. Thus, the user with id is deleted before I click on the delete confirm button and the error has occurred afterward.
Everything worked fine before. So, I don't know why this happend.
My code:
// GET: /User/Delete/5
[Authorize]
public ActionResult Delete(int id)
{
return View(GetByUserId(id));
}
// POST: /User/Delete/5
[Authorize]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Delete(Users user)
{
//some process
}
The second method invokes automatically after the first one is called.
The view:
<h2>Delete</h2>
<p class="error"><%= Html.Encode(ViewData["messages"]) %></p>
<h3>Are you sure you want to delete this?</h3>
<fieldset>
<legend>Fields</legend>
<div class="display-label">UserId</div>
<div class="display-field"><%= Html.Encode(Model.UserId) %></div>
<div class="display-label">UserName</div>
<div class="display-field"><%= Html.Encode(Model.UserName) %></div>
<div class="display-label">FullName</div>
<div class="display-field"><%= Html.Encode(Model.FullName) %></div>
<div class="display-label">Email</div>
<div class="display-field"><%= Html.Encode(Model.Email) %></div>
<div class="display-label">DayOfBirth</div>
<div class="display-field"><%= Html.Encode(String.Format("{0:MM/dd/yyyy}", Model.DayOfBirth))%></div>
<div class="display-label">Phone</div>
<div class="display-field"><%= Html.Encode(Model.Phone) %></div>
<div class="display-label">Active</div>
<div class="display-field"><%= Html.Encode(Model.Active) %></div>
</fieldset>
<% using (Html.BeginForm()) { %>
<p>
<input type="submit" value="Delete" /> |
<%= Html.ActionLink("Back to List", "Index") %>
</p>
<% } %>
You can create another view which will solve your purpose of confirmation delete.

Please find your modify code below.

Above code is same as your code and it's working fine. Please have a look.
I have a simple ASP.NET MVC 3 site, from my Controller out of the Edit Action I pass a Object (a class which is also mapped by nhibernate)
After editing and clicking save i pass it to the [HTTPPost] decoraded Method but and all properties are correct, excerpt the "id" property it hat a guid value equivalent to NULL (00000000-0000-000...).
Is there a problem using the Domain Model to strongly type my Views? May the problem be that Id has:
{get; private set;}
???
Thanks in advance.
Here The Code:
My View:
'#model fnh.DataModel.Kunde
#{
View.Title = "EditKunde";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>EditKunde</h2>
#using (Html.BeginForm()) {
#Html.ValidationSummary(true)
<fieldset>
<legend>Fields</legend>
#Html.EditorFor(model => model._id)
#Html.EditorFor(model => model._KdNr);
<div class="editor-label">
#Html.LabelFor(model => model._Name)
`enter code here` </div>
<div class="editor-field">
#Html.EditorFor(model => model._Name)
#Html.ValidationMessageFor(model => model._Name)
</div>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
}
<div>
#Html.ActionLink("Back to List", "Index")
'
My Controller Actions:
' public ActionResult EditKunde(Guid id)
{
return View(_kunden.GetKundeById(id));
}
[HttpPost]
public ActionResult EditKunde(Kunde kunde)
{
Ansprechpartner anp = new Ansprechpartner();
anp._Name = "JustATry";
kunde._Ansprechpartner.Add(anp);
`enter code here` _kunden.EditKunde(kunde);
return View();
}'
Are you adding the Id property to your form (maybe as a hidden field)?
It would be useful if you post the Action code (for both Edit Actions), and the View.
