Populating razor DropDownList from view model

Populating razor DropDownList from view model

I have a custom model (let's say CustomModel) for populating my razor
DropDownList in the view:
namespace MyNamespace.Models
{
public class SelectListItem
{
public string Value { get; set; }
public string Text { get; set; }
}
public class ComponentTypeModel
{
private readonly List<ComponentType> componentTypes;
[Display(Name = "Component Type")]
public int SelectedCompTypeId { get; set; }
public IEnumerable<SelectListItem> CompTypeItems
{
get
{
var allCompTypes = componentTypes.Select(f => new
SelectListItem
{
Value = f.Id.ToString(),
Text = f.Name
});
return allCompTypes;
}
}
public IEnumerable<SelectListItem> DefaultCompTypeItem
{
get
{
return Enumerable.Repeat(new SelectListItem
{
Value = "-1",
Text = "Select a
component type"
},
count: 1);
}
}
}
}
Then in my view I do the following using razor:
@model MyNamespace.Models.CustomModel
@Html.LabelFor(m => m.SelectedCompTypeId);
@Html.DropDownListFor(m => m.SelectedCompTypeId, Model.CompTypeItems);
but the second argument Model.CompTypeItems in line:
@Html.DropDownListFor(m => m.SelectedCompTypeId, Model.CompTypeItems);
is generating a compilation error saying that it is not valid. Any ideas?
