ASP.NET MVC - Display additional data in a View

Question

I have a View that displays a "grid" of all the Payments, which works fine.

Now, I would like to also add an additional dropdown to that View with the list of the Merchants.

How should I go about it? Add another field in my PaymentViewModel to have a list of the Merchants? Create two models? Can I create a partial view for just the dropdownlist and bind it another model?

I'm new to MVC so any thoughts are welcome.

Payments.cshtml

@model IEnumerable<MVC.Web.Models.PaymentsViewModel>

PaymentsViewModel.cs

public int PaymentID { get; set; }
public string Merchant { get; set; }

It depends. If you intend on having both values posted back together as a single model and you're using the default posting, then a single model works best. If you want to post with a javascript AJAX call, you could pass values in as multiple parameters easily enough. In this case, though, you can use @Html.DropDownListFor(x=> x.Merchant ...); throughout the app without creating separate views. — ps2goat

If you want one dropdown for the entire view, then you wouldn't add the list to PaymentsViewModel, as that would be adding a dropdown for each payment. Also this viewmodel should have a singular name because each represents a single item: PaymentViewModel.

Payments.cshtml

@model PaymentsViewModel

@Html.DropDownFor(... Model.Merchants...)// select into ListItems

<table>...
foreach(PaymentViewModel payment in Model.Payments)
    ...your existing "grid"

PaymentViewModel.cs

public int PaymentID { get; set; }
public string Merchant { get; set; }

PaymentsViewModel.cs

List<MerchantsViewModel> Merchants {get;set;}
List<PaymentViewModel> Payments {get;set;}

Alot of how I would go about this depends on what you are trying to accomplish with this dropdown though.
