My Model class is below:
I have three classes two of them are partial class and one is simple class.......
[MetadataType(typeof(RegistrationMetaData))]
public partial class Registration
{
}
public class RegistrationMetaData
{
public string Id { get; set; }
public string Name { get; set; }
public string Username { get; set; }
public virtual ICollection<Images> Images { get; set; }
}
[MetadataType(typeof(ImagesMetaData))]
public partial class Images
{
}
public class ImagesMetaData
{
public string id { get; set; }
public string stuid { get; set; }
public string stuimg1 { get; set; }
public virtual ICollection<Registration> Registrations { get; set; }
}
public class EmployeeViewModel
{
public string Name { get; set; }
public string stuimg1 { get; set; }
}
public class NotificationViewModel
{
public Registration registration { get; set; }
public Notification notification { get; set; }
public IEnumerable<EmployeeViewModel> EmployeeViewModel { get; set; }
public Images images { get; set; }
}
Then I have used the below code in controller class to fetch Images record with foreign key in registration table.
IEnumerable<EmployeeViewModel> model1 = null;
model1 = (from e in db.Registrations
join j in db.Images on e.Id equals j.stuid
where e.Email == Email
select new EmployeeViewModel
{
Name = e.Name,
stuimg1 = j.stuimg1
}).ToList();
var mixmodel = new NotificationViewModel
{
EmployeeViewModel = model1
};
return View(mixmodel);
Atlast my view page is like this:-
#model IEnumerable<Amar.Models.NotificationViewModel>
#foreach (var item in Model)
{
#item.EmployeeViewModel.stuimg1
}
But I am getting an error
System.Collections.Generic.IEnumerable' does not contain a definition for 'stuimg1' and no extension method 'stuimg1' accepting a first argument of type 'System.Collections.Generic.IEnumerable' could be found (are you missing a using directive or an assembly reference?)
I have gone through debugging my code is fine till controller page...but from view page the values are not showing.I think there is some little mistake i have made...
Please someone help me..I am trying to solve this problem since 2 weeks....
I want to fetch data from one more class on the same view page thats why I am using NotificationViewModel class.
return View(mixmodel);
Your view is expecting a type of IEnumerable<NotificationViewModel> but mixmodel is just a NotificationViewModel
I'm not seeing what you are achieving by having this additional class 'NotificationViewModel'. If your view were to be changed to expect an IEnumerable<EmployeeViewModal> you could pass in model1 directly.
You could then change your view to:
#foreach (var item in Model)
{
#item.stuimg1
}
If you do indeed need this extra layer of abstraction for some other part of your view then you need to sit and think about what is a a single instance and what is a list. Try drawing it if you're having trouble.

Iam new to MVC. I am using Code first way.I am inserting data at UI which is linked ViewModel to multiple table like Customer class,Address Class,etc.My viewmodel properties are not same in all the reflecting table, For eg.
public class CustDetVM
{ combined properties of all entity object }
public class Customer
{
[Key]
public string ID { get; set; }
public string Name { get; set; }
}
public class Address
{
[Key]
public string ID { get; set; }
public string A_Line1 { get; set; }
}
public class User
{
[Key]
public string ID { get; set; }
public string U_Group { get; set; }
}
I am adding data from my viewmodel to model. I am using three table to add data from viewmodel.
var query={// code removed for ..
code is debugged properly and storing in query
parameter.}
foreach(var data in query) //used debugger(breakpoint) here
{
db.Customer.Persist().InsertOrUpdate(data);//used debugger(breakpoint) here
}
db.SaveChanges();///used debugger(breakpoint) here not comming to this point and no error it is showing .
My mapping config is below
Mapper.Initialize(cfg =>
{
cfg.CreateMap<CustDetVM, Customer>()
.ReverseMap();
cfg.CreateMap<CustDetVM, Address>()
.ReverseMap();
});
What I am missing any help will be great for me.
I want to display both user info and address model in the same view.
These are my code structures:
In Data Access Layer, I have model classes:
User.cs:
public class User
{
[Key]
public int UserId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string RestaurantName { get; set; }
public string PrimaryPhone { get; set; }
}
Location.cs:
public class Location
{
public int Id { get; set; }
public string Line1 { get; set; }
public string Line2 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Country { get; set; }
public string ZipCode { get; set; }
public User User { get; set; }
}
So, I have two separate repositories for user and address models which perform add and get all functions which is working perfectly fine.
Now, I want both of this model information should be displayed in the view at the same time.
How can I combine both in the same view. I'm unable to do it. I can do it, but the thing is both are displayed in separate views.
Any advice would be appreciated!
Use a ViewModel. Your ViewModel could look something like this:
public class MyViewModel
{
public User UserVm {get;set;}
public Location LocationVm {get;set;}
}
Use the MyViewModel in your view. Your controller will accept a MyViewModel object.
You can then pass the LocationVm and UserVm objects from your viewModel to your repository.
Add One more Property To your User Model like below
-- Model Section
public class User
{
public List<Location> location {get;set;}
}
-- Controller Section
public ActionResult Index()
{
List<Location> loc= new List<Location>() { new Location{ City = "one" }, new
Location{ City = "two" } };
List<User> user= new List<User>() { new User{ FirstName = "A", location =
loc }, new User{ FirstName = "B" } };
return View(user);
}
-- View Section
#model IEnumerable<YourSolutionName.Models.User>
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.FirstName)
#{
if (item.location != null) {
foreach(var i in item.location)
{
<h1>#i.City</h1>
}
}
}
}
This is one approach by using, we can use two different models on same view.
As for demo i added static values you can add dynamic using your context object.
it may help you. Thank You
fist model get the list of questions.
but i am not able to access them while using #Html.HiddenFor() etc
these item are visible if i use #Html.Hidden() or anything without ....For method...
any idea how can i do this
here are my classes
public class QuestionModel
{
public int Id { get; set; }
public string QuestDes { get; set; }
public int Aspect { get; set; }
}
public class AnswerModel
{
public int Id { get; set; }
public string SelectedAns { get; set; }
public virtual QuestionModel Question { get; set; }
public virtual PersonModel Person { get; set; }
}
my controller code
public ActionResult GPage2()
{
var tview = new Tuple<List<QuestionModel>,AnswerModel>(getQuestions(),new AnswerModel());
return View(tview);
}
private List<QuestionModel> getQuestions()
{
var qList = (from q in dbcon.Questions
orderby q.Id
select q).ToList();
return qList;
}
in cshtml page
#model Tuple<List<QuestionModel>,AnswerModel>
<td> #Html.Label(Model.Item2.SelectedAns)</td>
#Html.LabelFor(.......................) not working
from what you have posted you need to use a view model that includes your 2 models
public class ViewModel{
public List<QuestionModel> Questions { get; set; }
public List<AnswerModel> Answers { get; set; }
}
then on your view
#model ViewModel
using this setup your for helpers should work. since it is a list putting them in a foreach would look something like this.
#foreach(var temp in Model.Questions){
#Html.LabelFor(x => temp.Aspect)
//etc
}
I have three objects:
public class Part
{
[Key]
public int ID { get; set; }
public string Number { get; set; }
public string Name { get; set; }
public int descID { get; set; }
}
public class Description
{
[Key]
public int descID { get; set; }
public string descName { get; set; }
public string description { get; set; }
}
public class GridPart
{
public string name{ get; set; }
public string number { get; set; }
public string description { get; set; }
}
I'm using LINQ to join Part and Description on the descID column:
public ActionResult Index()
{
var myParts = from p in db.Parts
join d in db.Description on p.descID equals d.DescriptorID
select new { Description = d.description, Name = p.name};
List<GridPart> partsList = new List<GridPart>();
foreach (var m in myParts)
{
GridPart gp = new GridPart();
gp.Name = m.name;
gp.description = m.description;
partsList.Add(gp);
}
return View(partsList);
}
If I was just using the Parts table, in the view I would do:
#model IEnumerable<MyApp.Models.Part>
What do I do if I'm using the joined table? This uses both Parts and Description, not to mention my List of GridParts, how do I pass this through to display all of the data I need?
Any advice is greatly appreciated.
If you pass an anonymous type to your view it won't be strongly typed. You can refer to your model like this instead
#Html.TextBox("Name")
or
#Html.Display("Name")
Although this will work I would advice against it - The better solution would be to go with a Viewmodel instead. This will make your view strongly typed.
Edit: Looking on this again I see that your actually not parsing the anonymous type to your view. Your parsing a list of GridParts.
You should be able to strongly type your view like your tried - just refer to GridParts instead of parts.
#model IEnumerable<MyApp.Models.GridPart>
Hope someone can help - this has been bugging me for around 2 hours - its probably something simple :)
Kendo UI Grid sends a request to my controller
http://localhost:1418/user/update?UserID=1&UserName=Admin&RoleName=Admin&Email=c.j.hannon%40gmail.com&Active=true&Company%5BCompanyID%5D=1&Company%5BCompanyName%5D=asd
However, the controller class 'Company' isnt bound by the binder? Can any one help my view model and controller action signature are below:
[HttpGet]
public JsonResult Update(UserViewModel model)
{
svcUser.UpdateUser(new UpdateUserRequest() {
UserID=model.UserID,
RoleID = model.RoleName,
Email = model.Email,
Active = model.Active.GetValueOrDefault(false),
UserName = model.UserName
});
return Json("", JsonRequestBehavior.AllowGet);
}
public class UserViewModel
{
public int UserID { get; set; }
public string UserName { get; set; }
public string RoleName { get; set; }
public string Email { get; set; }
public bool? Active { get; set; }
public CompanyViewModel Company { get; set; }
}
Cheers

A few things. Your immediate problem is that Company is mapped to a complex object not a primitive type. Kendo Grid just does not do this (as of this writing). Just guessing, but you probably want to setup a foreign key binding on the Grid and just pass back the Id of the company from a listbox. This is not as bad as you think and it will immediatly fix your problem and look nice too.
Maybe personal taste but seems to be a convention. Use the suffix ViewModel for the model that is bound to your View and just the suffix Model for your business objects. So a Kendo Grid is always populated with a Model.
Ex.:
public class UserModel
{
public int UserID { get; set; }
public string UserName { get; set; }
public string RoleName { get; set; }
public string Email { get; set; }
public bool? Active { get; set; }
public int CompanyID { get; set; }
}
public class CompanyModel
{
public int ID { get; set; }
public string Name { get; set; }
}
public class UserViewModel
{
public UserModel UserModel { get; set; }
public IList<CompanyModel> Companies { get; set; }
}
public ActionResult UserEdit(string id)
{
var model = new UserViewModel();
model.UserModel = load...
model.Companies = load list...
return View(model);
}
#model UserViewModel
...
column.ForeignKey(fk => fk.CompanyId, Model.Companies, "ID", "Name")
(Razor Notation)
BUT! This is just an example, you are better off Ajax loading the Grid with the IList becuase I assume you have many Users in the Grid at once, though you could server bind off the ViewModel with a List too. But the list of Companies is probably the same every time, so map it to the View just liek this rather than Ajax load it every time you do a row edit. (not always true)
