Hi Mark It seems like the issue arises from the way you're trying to iterate over the model in your partial view. Since NewinformationVm contains individual properties ( person and student ) and not a collection iterating over NewinformationVm directly isn't valid. If you want to display a list of items your ViewModel needs to contain a collection of items you can iterate over. Here’s a way to structure your ViewModel to support listing and iteration in the partial view: ViewModel with a Collection: public class NewInformationVm { public int Id { get; set; } public Person Person { get; set; } // Person model public Student Student { get; set; } // Student model public List Items { get; set; } // Collection of items public NewInformationVm() { Person = new Person(); Student = new Student(); Items = new List (); } } public class Item { public int ItemId { get; set; } public string ItemName { get; set; } // other properties... } Controller: Make sure your controller is populating the Items collection appropriately. public ActionResult Create() { var viewModel = new NewInformationVm { Items = GetItems() // Fetch or initialize your list of items here }; return View(viewModel); } private List GetItems() { // Logic to fetch or create items return new List { new Item { ItemId = 1 ItemName = Item 1 } new Item { ItemId = 2 ItemName = Item 2 } // Add more items... }; } Partial View: Update your partial view to iterate over the Items collection. @model myprojectname.ViewModels.NewInformationVm Item List @if (Model.Items != null && Model.Items.Any()) { @foreach (var item in Model.Items) { @item.ItemName } } else { No items available. } Main View: Ensure your main view is including the partial view correctly. @model myprojectname.ViewModels.NewInformationVm @Html.Partial(_PartialViewName Model) By adding a collection property ( Items ) to your ViewModel and ensuring the partial view iterates over this collection you should be able to list the records without encountering the model does not exist error.
