I am calling a partial view on which I want to collapse a few dropdown controls(previously created by using DropDownListFor). Because the controls are readonly, I just need to show the selected value on each control. I have created a list called "salutations" in the controller, and pass it as ViewData to my partial view. On the partial view I need to see the selected salutation (e.g.. Mr/Miss/Dr)in my div using @Html.DisplayFor. I tried creating a DisplayTemplate according to an online posting, but I am still having issues getting this to work.
Lookup list declared like this in controller:
var salutations = (IEnumerable<lu_Salutation>)ViewData["salutations"];
Here's my DisplayTemplate named LookupList.cshtml:
@model int
@using System.Linq
@vEmployee.SelectList1.Single(s => s.Value == Model.ToString()).Text
Of course, there's something wrong with the last line of the above code. vEmployee is the name of my model. How do I correct it?, and can I have a generic display template like the GridForeignKey Kendo EditorTemplate so I could easily pass the foreign key, the DisplayTemplate, and the lookup list to get just the text of the selected lookup value displayed?
Ideally, I will just like to have in my partial view, something like:
@Html.DisplayFor(model => model.id, "LookupList", SelectList((IEnumerable)ViewData["salutationList"], "TitleID", "Title"))
where TitleID and Title are respectively the value and text in the lookup list.
Models
public class lu_Salutation
{
public int TitleID { get; set; } // e.g. 1
public string Title { get; set; } // e.g. Mrs
}
ViewModel Class - I want to use just IDs here, but display the matching Texts from the lookup tables (e.g lu_Salutation) when needed
public class vEmployee
{
[Key]
public int EmployeeID { get; set; }
public int SalutationID { get; set; }
}
Controller
[HttpGet]
public ActionResult EmployeeDetails(int employeeID)
{
vEmployee SelectedEmployee = GetEmployees(employeeID).First();
ViewData["salutations"] = _db.lu_Salutation.OrderBy(e => e.Title);
return PartialView("_EmployeeDetails", SelectedEmployee);
}
private IEnumerable<vEmployee>GetEmployees(int employeeID)
{
IEnumerable<vEmployee> emp = (from e in _db.Employees
join c in _db.Contacts on e.EmployeeID equals c.EmployeeID
join u in _db.lu_Salutation on c.SalutationID equals u.TitleID into sal
from u in sal.DefaultIfEmpty()
where (e.EmployeeID == employeeID))
select new vEmployee
{
EmployeeID = e.EmployeeID,
SalutationID = c.SalutationID
}).AsEnumerable().OrderBy(m => m.EmployeeNumber).ThenBy(m => m.FirstName);
return emp;
}
