getting my form to autofill when editing using

getting my form to autofill when editing using - c#

very new to mvc. My problem is when I have a record I want to edit my view does not autofill the form. Specifically I am trying to enter a bid on an auction site. I want everything else to stay the same and only update the bid. if my form doesn't autofill then everything would be null. any help would be appreciated.
this is from the CarAuctionController
// GET: CarAuction/Edit/5
public ActionResult Edit(int id= 3)
{
CarList carList = db.CarLists.Find(id);
return View();
}
// POST: CarAuction/Edit/5
[HttpPost]
public ActionResult Edit(CarList carlist)
{
try
{
// TODO: Add update logic here
if (ModelState.IsValid)
{
db.Entry(carlist).State=EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return View("Index");
}
catch
{
return View();
}
}

The problem is that you returning "view", but you do not supply the "model" in which the engine can bind them together, thus the default is null.
return View("Index");
should be
return View("Index", carlist);

You are not passing the retrieved carlist model to the view. Therefore the view does not have access to the model and is not able to fill in the form.
// GET: CarAuction/Edit/5
public ActionResult Edit(int id= 3)
{
CarList carList = db.CarLists.Find(id);
// Change this:
return View(carList);
}

How to pass a value of class from view to controller in ASP.Net MVC

I can retrieve a string in this but when I try retrieving a class I'm having an exception error.
Customer = new Customer()
{
FirstName = Request.Form["FirstName"],
LastName = Request.Form["LastName "],
BillingAddress = new Address
{
StreetAddress1 = Request.Form["StreetAddress1"],
}
I already tried setting a value, it saves successfully, but when I'm getting the data from the value exception error occurs.By the way I'm using a model from the SDK. Thank you

Simple answer: You can't send complex datatypes in a form.
For your given example, you can just send "StreetAddress1" as a string (alongside with "FirstName" and "LastName") and build the Customer object in your controller.
Code for your view:
#model Customer
<div>
#using (Html.BeginForm("Action", "Controller", FormMethod.Post))
{
#Html.TextBoxFor(m => m.FirstName)<br />
#Html.TextBoxFor(m => m.LastName)<br />
#Html.TextBoxFor(m => m.BillingAddress)<br />
<button type="submit">Save</button>
}
</div>
If you follow this approach, MVC already serializes the Customer object for you:
[HttpPost]
public ActionResult Action(Customer c)
{
string FullName = c.FirstName + " " + c.LastName
}

Use FormCollection Class in You Controller .. This Will Get You All The Posted Values From Use .. Then u Can Extract Values By Key FromCollection Keys .. Create New Object Based On The Value You Got From The FormCollection , Simply Add a FromCollection Parameter
public ActionResult (FormCollection F)
{
}

MVC 5 Data was not pass to mode from view to controller

I have a productModelView which contains 2 Model.All the data in the product and inventory fields was not populated to the model when pass back to the model in the controller.
public class ProductDetails
{
public ProductsTb Product { get; set; }
public InventoryTb ProductInventory { get; set; }
public List<ItemTypeLibrary> ProductTypeList { get; set; }
}
To make code short.i will just show 1 attribute which is inside the productsTB
public ActionResult Create()
{//load up create page to populate product type list
ProductDetails pd = new ProductDetails();
pd.ProductTypeList = db.ItemTypeLibraries.ToList();
return View(pd);
}

It's not clear from what you posted as to what isn't being bound, but if you are expecting the entire viewmodel, then remove the Bind(Include...) attribute. It's not needed in that case.

Another option is, use FormCollection instead of passing the model, in case of custom attributes to include object.
[HttpPost]
public ActionResult Create(FormCollection form)
{
// here you can retrieve attributes from form and assign to your object
productsTb.Id = form["Id"]; // it should match the name of tag in View
return View(productsTb);
}

Your view is strongly typed to a CreateStudent class and the view code is using Model.Genders collection property when you use the DropDownListFor helper method. But in your http post action, you are calling the return View() method without passing a valid CreateStudent object and in another case without populating the Genders property. So when razor executes the view code, the model value is null ( because you did not pass anything to the view)
You need to set the Genders property again before returning the posted view model back to the view.
[HttpPost]
public ActionResult Create(CreateStudent student)
{
var genderList = new List<SelectListItem>()
{
new SelectListItem { Text = Constants.Gender.Boy, Value = Constants.Gender.Boy},
new SelectListItem { Text = Constants.Gender.Girl, Value = Constants.Gender.Girl},
};
if (ModelState.IsValid)
{
var result = _student.Insert(mappedStudent);
if (result)
{
return RedirectToAction("Index");
}
else
{
student.Genders = genderList;
TempData["Message"] = "Failed to create new student";
return View(student); // Passing the object here to view
}
}
//Model validation fails. Return the same view
student.Genders = genderList;
return View(student);
}
}
Also there no need for an extra casting. Model.Genders is of type List<SelectListItem>
#Html.DropDownListFor(o=>o.Gender,Model.Genders, new { #class = "form-control" })

Pass data from ViewModel to Controller [duplicate]

This question already has an answer here:
Does the name of parameter have to be model?

}
Then this is the Action Method:
[HttpPost]
public ActionResult Update(ViewModels.UpdateReservationVM reservation)
{
if (ModelState.IsValid)
{
db.Entry(reservation).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return View(reservation);
}
Then this is my View Model:
public class UpdateReservationVM
{
public virtual Reservation Reservation { get; set; }
public virtual Payment Payment { get; set; }
public virtual FlightInfo Flight { get; set; }
public virtual RoomReservation Room { get; set; }
public virtual Transfer Transfer { get; set; }
}
What is wrong with this code? Tried to debug it, it always goes to the action method of the controller but values passed are all NULL.

Add an antiforgerytoken in your form:
#using (Html.BeginForm("Update", "Reservations", FormMethod.Post, new { #class = "form-horizontal" }))
{
#Html.AntiForgeryToken()
#*
rest of code
*#
}

Try...
[HttpPost]
public ActionResult Update(ViewModels.UpdateReservationVM reservation)
{
if (ModelState.IsValid)
{
db.Reservation.Attach(UpdateReservationVM.reservation);
db.Entry(UpdateReservationVM.reservation).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return View(reservation);
}
Check to see that reservation (lowercase) is not null when debugging.
On a side note, you may want to change
public ActionResult Update(ViewModels.UpdateReservationVM reservation)
to
public ActionResult Update(UpdateReservationVM reservation)
and add a using statement at the top of your controller to include the viewmodel namespace...
using YOURPROJECTNAME.NAMEOFVIEWMODELSFOLDER;
So, in my case its
using salesWebsite.viewModel;

C# (C-Sharp) is a programming language developed by Microsoft that runs on the .NET Framework.

getting my form to autofill when editing using - c#

The problem is that you returning "view", but you do not supply the "model" in which the engine can bind them together, thus the default is null. return View("Index"); should be return View("Index", carlist);

You are not passing the retrieved carlist model to the view. Therefore the view does not have access to the model and is not able to fill in the form. // GET: CarAuction/Edit/5 public ActionResult Edit(int id= 3) { CarList carList = db.CarLists.Find(id); // Change this: return View(carList); }
