First step...Opened WCF created IService:
namespace CRUDOperationWCFMVC
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
[ServiceContract]
public interface IService1
{
[OperationContract]
bool CreateDetails(EmployeeDetails employeeDetails);
[OperationContract]
bool UpdateDetails(EmployeeDetails employeeDetails);
[OperationContract]
bool DeleteDetails(int id);
[OperationContract]
List<EmployeeDetails> GetDetails();
}
public class EmployeeDetails
{
[DataMember]
public int EmpID { get; set; }
[DataMember]
public string Name { get; set; }
[DataMember]
public string Location { get; set; }
[DataMember]
public int? Salary { get; set; }
}
}
Step 2: then I implemented service code:
public class Service1 : IService1
{
DataClasses1DataContext dcd = new DataClasses1DataContext();
public bool CreateDetails(EmployeeDetails employeeDetails)
{
Nevint emp = new Nevint();
emp.EmpID= employeeDetails.EmpID;
emp.Name = employeeDetails.Name;
emp.Location = employeeDetails.Location;
emp.Salary = employeeDetails.Salary;
dcd.Nevints.InsertOnSubmit(emp);
dcd.SubmitChanges();
return true;
}
public bool DeleteDetails(int id)
{
var delete = (from v in dcd.Nevints where v.EmpID==id select v).FirstOrDefault();
dcd.Nevints.DeleteOnSubmit(delete);
dcd.SubmitChanges();
return true;
}
public List<EmployeeDetails> GetDetails()
{
List<EmployeeDetails> details = new List<EmployeeDetails>();
var select= (from v in dcd.Nevints select v);
foreach (var i in select)
{
EmployeeDetails emp = new EmployeeDetails();
emp.EmpID = i.EmpID;
emp.Name = i.Name;
emp.Location = i.Location;
emp.Salary = i.Salary;
details.Add(emp);
}
return details;
}
public bool UpdateDetails(EmployeeDetails employeeDetails)
{
var update = (from v in dcd.Nevints.ToList() where employeeDetails.EmpID==v.EmpID select v).FirstOrDefault();
update.EmpID = employeeDetails.EmpID;
update.Name = employeeDetails.Name;
update.Location = employeeDetails.Location;
update.Salary = employeeDetails.Salary;
dcd.SubmitChanges();
return true;
}
}
Step 3: then I add linq to sql, opened my ASP.NET MVC project for consuming, and added a controller and wrote this code:
namespace ConsumingClient.Controllers
{
public class EmpdetailsController : Controller
{
ServiceReference1.Service1Client serobj=new ServiceReference1.Service1Client();
ServiceReference1.EmployeeDetails empdetails=new ServiceReference1.EmployeeDetails();
// GET: Empdetails
public ActionResult Index()
{
List<employee> lstemp = new List<employee>();
var result = serobj.GetDetails();
foreach (var i in result)
{
employee emp = new employee();
empdetails.EmpID = i.EmpID;
empdetails.Name = i.Name;
empdetails.Location = i.Location;
empdetails.Salary = i.Salary;
lstemp.Add(emp);
}
return View(result);
}
// GET: Empdetails/Details/5
public ActionResult Details(int id)
{
Employees emp = new Employees();
return View();
}
// GET: Empdetails/Create
public ActionResult Create()
{
return View();
}
// POST: Empdetails/Create
[HttpPost]
public ActionResult Create(Employees employees)
{
try
{
// TODO: Add insert logic here
empdetails.EmpID=employees.EmpID;
empdetails.Name = employees.Name;
empdetails.Location = employees.Location;
empdetails.Salary = employees.Salary;
serobj.CreateDetails(empdetails);
return RedirectToAction("Index");
}
catch
{
return View();
}
}
// GET: Empdetails/Edit/5
public ActionResult Edit(int id)
{
Employees emp = new Employees();
var result = serobj.GetDetails().FirstOrDefault(a=>a.EmpID==id);
emp.EmpID = result.EmpID;
emp.Name = result.Name;
emp.Location = result.Location;
emp.Salary = result.Salary;
return View(emp);
}
// POST: Empdetails/Edit/5
[HttpPost]
public ActionResult Edit(Employees employees)
{
try
{
// TODO: Add update logic here
empdetails.EmpID = employees.EmpID;
empdetails.Name = employees.Name;
empdetails.Location = employees.Location;
empdetails.Salary = employees.Salary;
serobj.UpdateDetails(empdetails);
return RedirectToAction("Index");
}
catch
{
return View(employees);
}
}
// GET: Empdetails/Delete/5
public ActionResult Delete(int id)
{
Employees emp = new Employees();
var result = serobj.GetDetails().FirstOrDefault(a=>a.EmpID==id);
emp.EmpID = result.EmpID;
emp.Name = result.Name;
emp.Location = result.Location;
emp.Salary = result.Salary;
return View(emp);
}
// POST: Empdetails/Delete/5
[HttpPost]
public ActionResult Delete(int id, FormCollection collection)
{
try
{
// TODO: Add delete logic here
serobj.DeleteDetails(id);
return RedirectToAction("Index");
}
catch
{
return View(id);
}
}
}
}
Data was displaying fine. I can create data.
However, when I click on edit and delete, I'm getting an error:
ERROR Message "Server Error in '/' Application.
The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Edit(Int32)' in 'ConsumingClient.Controllers.EmpdetailsController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters
This error is thrown if you attempt to call this controller action and you do not specify the id either in the path portion or as query string parameter. Since your controller action takes an id as parameter you should make sure that you always specify this parameter.
Make sure that when you are requesting this action you have specified a valid id in the url:
http://example.com/somecontroller/Edit/123
If you are generating an anchor, make sure there's an id:
#Html.ActionLink("Edit", "somecontroller", new { id = "123" })
If you are sending an AJAX request, also make sure that the id is present in the url.
If on the other hand the parameter is optional, you could make it a nullable integer:
public ActionResult Edit(int? id)
but in this case you will have to handle the case where the parameter value is not specified.

Try to use a DropDownListFor instead of a DropdownList. The error you mention means that you are having NULL in the SelectListItem. You should create a list of ListItem in the DropDownList.
(I'm not sure if I'm correct or not. I'm just trying to help quickly.)
I have a view named Register.cshtml and 2 partialview named _AddUser.cshtml And _UserList.cshtml.
When I run the project shows register.cshtml and _AddUser.cshtml load in view. I want to load _UserList partialview after success inserted in _AddUser partialview.

This error comes to me.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

I searched but there is not suitable answers for me.
The spell of my controller is correct. I tried and checked many times.
I did not customize my rounting Globle.asax
I checked the "Web" tab under my project's properties, the "SpecificPage is tickled without any contents"
Everything is by default. Anyway here is the default code for rounting. Who knows why?Thanks
