Why wont Umbraco let me bind a generic list of Objects to my View?
Something strange is happening in my umbraco project where I have a repository set up like so;
public class HireItemsRepo:BaseGenericRepository<YouHireItContext,HireItem>
{
public List<HireItemViewModel> PopulateHireItemViewModel(RenderModel model)
{ List<HireItemViewModel> HireItems = new List<HireItemViewModel>();
foreach (var Hireitem in base.GetAll())
{
HireItems.Add(
new HireItemViewModel(model.Content)
{
Title = Hireitem.Title,
Price = Hireitem.Price
}
);
}
return HireItems;
}
}
which I'm using in my controller like this
public class HiresController : RenderMvcController
{
// GET: Hire
public override ActionResult Index(RenderModel model)
{
HireItemsRepo repo = new HireItemsRepo();
var VM = repo.PopulateHireItemViewModel(model);
return View("Hires",VM.ToList());
}
}
It's strange because if I try to use that model as a List, Umbraco will blow up with the following error;
Cannot bind source type System.Collections.Generic.List`1[[You_Hire_It.Models.HireItemViewModel, You_Hire_It, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]] to model type Umbraco.Web.Models.RenderModel.
However, if I refactor all the code to use the model on it's own as if I only have one set of values to use, it has no problem with it!
Could anybody point me in the right direction with this please?
public class HiresController : RenderMvcController
{
// GET: Hire
public override ActionResult Index(RenderModel model)
{
HireItemsRepo repo = new HireItemsRepo();
var VM = repo.PopulateHireItemViewModel(model);
return base.Index(VM.ToList());
}
}
@inherits Umbraco.Web.Mvc.UmbracoViewPage<List<You_Hire_It.Models.HireItemViewModel>>

Sorry, I just passed a wrong tip. You need to create a model class where the list is a property. Here is an example I make when I have a scenario like yours.
public class MyNewViewModel : RenderModel
{
public MyNewViewModel(IPublishedContent content) : base(content) { }
//Custom properties here...
public List<You_Hire_It.Models.HireItemViewModel> Items { get; set; }
}
public class HiresController : RenderMvcController
{
// GET: Hire
public override ActionResult Index(RenderModel model)
{
HireItemsRepo repo = new HireItemsRepo();
var mynewviewmodel = MyNewViewModel(model.Content);
mynewviewmodel.Items = repo.PopulateHireItemViewModel(model);
return base.Index(mynewviewmodel);
}
}
@inherits Umbraco.Web.Mvc.UmbracoViewPage<MyNewViewModel>
@if (Model.Items != null && Model.Items.Any())
{
foreach (var item in Model.Items)
{
}
}
And its HireItemViewModel class no longer needs to inherit the RenderModel

Thanks for the quick reply!
I tried this but i get the following error;
Ah, Sorted!
It turns out I just had to change my Layout file's @inherit statement to this;
