Return List To View

Every Time I loop through the viewbag it gives this error


object' does not contain a definition for 'Name'


This My Action

public ActionResult AssignTask()
{
var List = db.Employees.Select(x => new
{
id = x.id,
Name = x.Name
}).ToList();

ViewBag.Emp_data = List;

return View();
}


and this is my view
enter image description here

Answer

This code returns a List<anonymous>

var List = db.Employees.Select(x => new 
{ 
    id = x.id, 
    Name = x.Name
}).ToList();

so that's why you can't access Name property in the foreach loop in your view.

I would suggest using a strongly typed ViewModel class to hold the data and avoiding ViewBag. The ViewModel should be in Models folder and look like below

public class EmployeeViewModel
{
    public int ID { get; set; }
    public string Name { get; set; }
}

Change your controller as below

public ActionResult AssignTask() 
{
    var model = db.Employees.Select(x => new EmployeeViewModel
    { 
        ID = x.id, 
        Name = x.Name
    }).ToList();

    return View(model);
}

and in your view

@model List<EmployeeViewModel>

<h2>AssignTask</h2>
<div class="row">
    <div class="form-group">
        <div style="overflow-y:scroll; overflow-x:hidden; height:400px;">
            @foreach (var item in Model)
            {
                <div class="col-lg-4 col-md-4">
                    <label>@item.Name</label>
                    <input type="checkbox" class="checkbox" name="SelectEmp" value="@item.ID" />
                </div>
            }
        </div>
    </div>
</div>
