The type of FromTime and ToTime is long and i want to display it as Time and then save it back as long.
If I have a type of long in the database and i need to display it as Time in Model View Controller ASP.Net then save it as a long again into the database. How can i do this?

I have a Course Table and a Hole Table in SQL. There is a foreign Key in the hole Table that is set to the CourseId.
This is so that when I create a hole I can assign it to the relevant course.
In my View I have a dropdownlistfor that has a list of courses to select from when creating the hole. However when I try and post back the values the courseID does not post back.
HoleViewModel
// GET: HoleViewModels/Create
public ActionResult Create()
{
var dbcourse = db.Course.ToList();
//Make selectlist, which is IEnumerable<SelectListItem>
var courseNameDropdownList = new SelectList(db.Course.Select(item => new SelectListItem()
{
Text = item.CourseName.ToString(),
Value = item.CourseId.ToString()
}).ToList(), "Value", "Text");
// Assign the Selectlist to the View Model
var viewCourse = new HoleViewModel()
{
Course = dbcourse.FirstOrDefault(),
// The Dropdownlist values
CourseNamesDropdownList = courseNameDropdownList,
};
return View(viewCourse);
}
// POST: HoleViewModels/Create
// To protect from overposting attacks, please enable the specific properties you want to bind to, for

</div>
So when the holeview posts back holeNumber, Par, Length, StrokeIndex, CourseID. it passes all data into the hole table other than the courseId which it posts a null.
What am I missing from the POST to get the CourseId to be entered in the Database.
Problem is occurring here:
#Html.DropDownList("KategoriId", null, htmlAttributes: new { #class = "form-control" })
Here is my Controller:
public ActionResult Create()
{
ViewBag.KategoriId = new SelectList(db.Kategoris, "KategoriId", "KategoriAdi");
return View();
}
Here is my View:
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.KategoriId, "KategoriId", htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownList("KategoriId", null, htmlAttributes: new { #class = "form-control" })
#Html.ValidationMessageFor(model => model.KategoriId, "", new { #class = "text-danger" })
</div>
</div>
You can do this Type Casting ViewBag to IEnumerable<SelectListItem> in CSHTML:
CSHTML Code:
#Html.DropDownList("your_key", (IEnumerable<SelectListItem>)ViewBag.KategoriId, "--Select Any--", new { #class = "form-control"})
Controller code:
IList<SelectListItem> items = new List<SelectListItem>();
foreach (var item in db.Kategoris.ToList())
{
SelectListItem sellist = new SelectListItem();
sellist.Value = item.code.ToString();
sellist.Text = item.name;
items.Add(sellist);
}
ViewBag.KategoriId = items; // at the end this item should be list of `SelectListItem`
Write your #Html.DropDownList() as follows:
#Html.DropDownList("KategoriId", ViewBag.KategoriId as SelectList,"Select Ketegory Id", htmlAttributes: new { #class = "form-control" })
This should fix your problem!
I know that the question was asked and answered many times, but unfortunately no one of the answers helped me.
I have tree POCO models, which are Pharmacy, Address and Company gathered together into a ViewModel PharmacyVM:
public class PharmacyVM
{
public Pharmacy pharmacyProp { get; set; }
public Address addressProp { get; set; }
public Company companyProp { get; set; }
public int CityId { get; set; }
public PharmacyVM()
{
pharmacyProp = new Pharmacy();
addressProp = new Address();
companyProp = new Company();
}
}
Don't laugh at the properties names; at the start, they had been normal (Address, Company and Pharmacy) I changed them according to one of the lots of answers in here, but... it didn't help :(
In the Get action of the Create method I'm trying to manually create the PharmacyVM object and pass it to the view:
public ActionResult Create()
{
ViewBag.CityId = new SelectList(db.Cities, "Id", "Name");
ViewBag.CompanyId = new SelectList(db.Companies, "Id", "Name");
ViewBag.AddressId = new SelectList(db.Addresses, "Id", "Name");
ViewBag.CityId = new SelectList(db.Cities, "Id", "Name");
ViewBag.RegionId = new SelectList(db.Regions, "Id", "Name");
ViewBag.DistrictId = new SelectList(db.Districts, "Id", "Name");
ViewBag.MicrodistrictId = new SelectList(db.Microdistricts, "Id", "Name");
ViewBag.StreetId = new SelectList(db.Streets, "Id", "Name");
ViewBag.VillageId = new SelectList(db.Villages, "Id", "Name");
var pharmacyVM = new PharmacyVM();
return View(pharmacyVM);
}
There is a standard Razor code in the view:
#model MEDONET.Models.PharmacyVM
#{
ViewBag.Title = "Create";
}

And then in the Post action of the Create method, I'm trying to create b and c variables:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(PharmacyVM model, HttpPostedFileBase LargeImageFile)
{
if (ModelState.IsValid)
{
string LargeImageFileName = Path.GetFileNameWithoutExtension(LargeImageFile.FileName);
string LargeImageExtansion = Path.GetExtension(LargeImageFile.FileName);
LargeImageFileName = LargeImageFileName + DateTime.Now.ToString("yymmssfff") + LargeImageExtansion;
LargeImageFileName = Path.Combine(Server.MapPath("~/Images/Pharmacy/Banners/"), LargeImageFileName);
int b = model.CityId;
int c = model.addressProp.RegionId.Value;
//Address address = new Address()
//{
// Id = 12,//db.Addresses.AsEnumerable().Last().Id + 1,
// RegionId = PharmacyVM.Address.RegionId,
// DistrictId = PharmacyVM.Address.DistrictId,
// CityId = PharmacyVM.Address.CityId,
// MicrodistrictId = PharmacyVM.Address.MicrodistrictId,
// StreetId = PharmacyVM.Address.StreetId,
// VillageId = PharmacyVM.Address.VillageId,
// Building = PharmacyVM.Address.Building,
// Cab = PharmacyVM.Address.Cab
//};
//Address address = new Address
//{
// Id = 12,//db.Addresses.AsEnumerable().Last().Id + 1,
// RegionId = 1,
// DistrictId = 1,
// CityId = 1,
// MicrodistrictId = 1,
// StreetId = 1,
// VillageId = 1,
// Building = "1",
// Cab = "1"
//};
//db.Addresses.Add(address);
db.SaveChanges();
var pharmacy = new Pharmacy
{
Name = model.pharmacyProp.Name,
//AddressId = address.Id,
IsGov = model.pharmacyProp.IsGov,
CompanyId = model.pharmacyProp.CompanyId,
LargeImage = "~/Images/Pharmacy/Banners/" + LargeImageFileName
};
LargeImageFile.SaveAs(LargeImageFileName);
db.Pharmacies.Add(pharmacy);
db.SaveChanges();
ModelState.Clear();
return RedirectToAction("Index");
}
}
Unlike first variable b, the second one c is gonna be null because the addressProp property is null.
So why is it so strange? How can I use ViewModel without duplicating original model's fields?
why are you use
int b= model.addressProp.RegionId.Value
instead of
int b=model.addressProp.RegionId
Even for your good cording the best and good way is remove all View bag and
Add all View bag properties to PharmacyVM Class
Dont use two properties for view binding
Example
public class PharmacyVM
{
public Pharmacy pharmacyProp { get; set; }
public Address addressProp { get; set; }
public Company companyProp { get; set; }
public int CityId { get; set; }
public SelectList CityIdList { get; set; }
public PharmacyVM()
{
pharmacyProp = new Pharmacy();
addressProp = new Address();
companyProp = new Company();
CityIdList =new SelectList(db.Cities, "Id", "Name");
}
}
public ActionResult Create()
{
var pharmacyVM = new PharmacyVM();
return View(pharmacyVM);
}
#model PharmacyVM
#using (Html.BeginForm())
{
#Html.HiddenFor(m => m.CityId )
<div class="editor-label">
#Html.LabelFor(m => m.Name)
</div>
<div class="editor-field">
#Html.EditorFor(m => m.Name)
#Html.ValidationMessageFor(m => m.Name)
</div>
<button type="submit">Create</button>
}
[HttpPost]
public ActionResult Create(PharmacyVM model)
{
int c = model.addressProp
return View(viewModel);
}

Im new to ASP .NET MVC Web Aplications and i please need some help. I need to summ two values ("Cena" and "Kolicina") and save into textbox "Znesek". How should i do this? I tried this (How to multiply values of two textboxes in Asp.net MVC) but its not working for me :/
Here is my .cshtml file:

Please help me, what i need to change or where i need to do some action?
EDIT:
Sure, i have #Html.BeginForm and everything what is needed for View code, this is just partial code. Everything is working, i can save all to SQL database and display it, i just down know how to multiple fields...
Here is my controler POST Code:
public ActionResult Create()
{
ViewBag.zapStDoumenta_tk = new SelectList(db.dokumentGlava, "zapStDokumenta", "zapStDokumenta");
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "zapStPostavke,artikel,kolicina,cena,znesek,davek,popustNaPostavko,zapStDoumenta_tk")] postavkaDokumenta postavkaDokumenta)
{
if (ModelState.IsValid)
{
db.postavkaDokumenta.Add(postavkaDokumenta);
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.zapStDoumenta_tk = new SelectList(db.dokumentGlava, "zapStDokumenta", "krajIzdaje", postavkaDokumenta.zapStDoumenta_tk);
return View(postavkaDokumenta);
}
Try this javascript code. This should work.
$(function(){
$("#kolicina,#cena").keyup(function(e){
var val1=$("#kolicina").val(),
val2=$("#cena").val(),
result="";
if(val1.length > 0){
result += val1;
}
if(val2.length > 0){
result += val2;
}
$("#znesek").val(result);
});
});
I am trying to populate a dropdownlist and then post it to db but for some reason it is giving error, please advice.

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" })
