I am having difficulties displaying a list of data that incoporates two database objects.

My view is strongy typed to a view model that includes a list of customers and a list of customer sites (each stored in their own table). Im currently using two for each statments to render both lists, but really i need one list that contains both objects, in a nutshell its a list of customer sites that also contains customer names from the customer table.

This is my viewmodel

namespace CustomerDatabase.WebUI.Models
{
public class CustomerSitesListViewModel
{
    public IList<CustomerSite> CustomerSites { get; set; }
    public PagingInfo PagingInfo { get; set; }
    public IList<Customer> customers { get; set; }
}
}

This is the code im currently using in the view, the customer sites are contained in a partial view, it would be ideal if i could add the customer name in the partial view but the only way i can work out how to access both objects is to use two for each statements

<%@ Page T开发者_开发问答itle="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master"   Inherits="System.Web.Mvc.ViewPage<CustomerDatabase.WebUI.Models.CustomerSitesListViewModel>    " %>
<% foreach (var customer in Model.customers) { %>
<%:customer.CustomerName%></li>
<%} %>
<% foreach (var customerSite in Model.CustomerSites) { %>
<% Html.RenderPartial("CustomerSiteSummary", customerSite); %>
<%} %>

This is my partial view

<%@ Control Language="C#"   Inherits="System.Web.Mvc.ViewUserControl<CustomerDatabase.Domain.Entities.CustomerSite>" %>
<div class="item">
<div class="customer-list-item">
<%: Model.AddressLine1%>
<%: Model.AddressLine2%>
<%: Model.AddressLine3%>
<%: Model.Town%>
<%: Model.County%>
<%: Model.Postcode%>
<%: Model.ContactName%>
<%: Model.ContactNo%>
<%: Model.ContactEmail%>

This is my controller code which sets up the two lists

public ViewResult List([DefaultValue(1)] int page)
    {
        var customerSitesToShow = customerSiteRepository.CustomerSites;
        var customersToShow = customerRepository.Customers;
        var viewModel = new CustomerSitesListViewModel
        {

            CustomerSites = customerSitesToShow.Skip((page - 1) *   PageSize).Take(PageSize).ToList(),
            customers = customersToShow.Skip((page - 1) * PageSize).Take(PageSize).ToList(),
            PagingInfo = new PagingInfo
            {
                CurrentPage = page,
                ItemsPerPage = PageSize,
                TotalItems = customerSitesToShow.Count()
            }
        };

        return View(viewModel);  //Passed to view as ViewData.Model (or simply model)
    }

}
}

Is there another way to accesss both objects from the view without the for each statment so i can merge the two lists together in the partial view.

<% foreach **(var customer in Model.customers)** { %>

Thanks for any advice anyone may be able to offer.


Sorry, but your question is still a bit vague for me, but in any case, it seems you want some data structure like this.

namespace CustomerDatabase.WebUI.Models
{
public class CustomerSitesListViewModel
{    
    public PagingInfo PagingInfo { get; set; }
    public IList<Customer> customers { get; set; }
}
public class Custmoer
{
     public IList<CustomerSite> CustomerSites { get; set; }
     //other customer properties
}
}

You can easily build that kind of view model in the controller and then adjust your views like that. You can also use a grid or build one with a foreach loop for the list of data (like you are doing already).
