    <p>I am building my first MVC app after following the Music Store tutorial and have ran into some problems when trying to pass data between strongly typed views. </p> <p>I have two datatypes with their own strongly typed views</p> <p>Customer Customer Site</p> <p>In the index view of customer site (which returns a lits of customer sites) i need to display the customer name next to each site address, the view is strongly typed to customer site but the customer name is stored in the customer table so it wont allow me to access this directlty from the model?</p> <p>I know that one option is to use the viewbag, i have successfully done this to display the Customer Name in a drop down list on my create view using the following code </p> <p>Customer Site Controller/////////</p> <pre><code>public ActionResult Create() { ViewBag.Id = new SelectList(db.Customers, "Id", "CustomerName"); return View(); } </code></pre> <p>Index view//////////</p> <pre><code>@Html.DropDownListFor(model =&gt; model.CustomerId, (IEnumerable&lt;SelectListItem&gt;)ViewBag.Id) </code></pre> <p>This works fine but now i need to the customer name to be inserted each table row rather than a drop down list. Can anyone kindly offer any pointers on how i can retrieve a list of customer names to be rendered in a table in the index view of the customer site? </p> <p>Also is the viewbag the best way to pass data between views or are there other alternative methods? Is there a way to strongly type a view with multiple data types?</p> <p>Any advice anyone can offer would be great.</p> <p>Kind Regards</p> <p>Liam</p>

    1. COIt sounds like the problem is that you need to combine information from two classes - Customer and CustomerSite. Is this correct?

    2. COYou can create a ViewModel class that combines all the necessary information into one class. This will help keep your models very pure without limiting the functionality of your views.

    3. CO@tomas - Yep, see my answer below which shows that exact principal. In fact, in my designs even if the view is only going to need a single domain entity I *always* wrap it in a ViewModel first just to make it easier to work with if later I need to pass along other information. It's a little more effort up front but pushes the idea of separation a bit more. =)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
