    <p>Instead of using <code>Html.RenderPartial()</code> put your partial view in Shared/EditorTemplates/ and name it the name of the type (in this case <code>ZipCodeViewModel</code>). Then you can use <code>Html.EditorFor()</code> passing in the expression for the property. EditorFor() prefixes the fields correctly so that the model binder in MVC can put your data in place correctly.</p> <p>So something like this</p> <pre><code>@model UserViewModel ..... @Html.EditorFor(m =&gt; m.ZipCode); </code></pre> <p>I'll try to dig up some links and resources but wanted to get the answer out there for you.</p> <p><strong>EDIT</strong>: This blog post seems to go over the basics of EditorFor() extension and EditorTempaltes: <a href="http://blogs.msdn.com/b/nunos/archive/2010/02/08/quick-tips-about-asp-net-mvc-editor-templates.aspx" rel="noreferrer">Quick Tips About ASP.NET MVC: Editor Tempaltes</a></p> <p>Anyway, when you use those <code>Html.TextBoxFor()</code> or <code>Html.DropDownFor()</code> extensions, what they do is get the full name of the property from the expression you pass in and set the HTML input element's name and id attributes to that. Example could be:</p> <pre><code>@Html.TextBoxFor(m =&gt; m.Person.FirstName) </code></pre> <p>would render</p> <pre><code>&lt;input id="Person_FirstName" name="Person.FirstName" type="text" value="&lt;what ever was in FirstName&gt;" /&gt; </code></pre> <p>Those input names and values are the key/value pairs in the post data. The default ASP.NET MVC model binder tries to match those keys up to the models your controller actions take in. If it can find a match then it sets the value.</p> <p>So your problem above is probably because the input names in your partial view are from the <code>ZipCodeViewModel</code> down but your action is taking in a <code>UserViewModel</code>. The <code>EditorFor()</code> prefixes the names for you so it can basically render a partial view that will post data back that can be bound for you. Although you could set the name attributes yourself on the input elements (or flatten everything as you suggested in the comments) has these helpers in there to do it for you.</p> <p>I hope that helps explain what is happening and a possible solution for you.</p>

    1. COI can just add fields from my ZipCode model to User model and all works. But then i have to create the ZipCode view in the View. It isn`t good implementation of the MVC. And I goona get something like UserControl, which I can use in the various places of my program.

    2. COI would recommend not cluttering up your User model if you don't need/want to and the EditorFor() helper with the EditorTemplates create a reusable partial view. I believe this is what you are after.

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.
