    <p>I'm having trouble with <code>DropDownListFor</code> in my MVC3 app. I was able to use StackOverflow to figure out how to get them to appear on the View, but now I don't know how to capture the values in its corresponding properties on the View Model when it's submitted. In order to get this to work I had to create an inner class that had an ID and a value property, then I had to use an <code>IEnumerable&lt;Contrib&gt;</code> to satisfy the <code>DropDownListFor</code> parameter requirements. Now, however, how is MVC FW supposed to map the value that is selected on this drop-down back into the simple string property on my view model? </p> <pre><code>public class MyViewModelClass { public class Contrib { public int ContribId { get; set; } public string Value { get; set; } } public IEnumerable&lt;Contrib&gt; ContribTypeOptions = new List&lt;Contrib&gt; { new Contrib {ContribId = 0, Value = "Payroll Deduction"}, new Contrib {ContribId = 1, Value = "Bill Me"} }; [DisplayName("Contribution Type")] public string ContribType { get; set; } } </code></pre> <p>In my View I place the dropdown on the page like this:</p> <pre><code>&lt;div class="editor-label"&gt; @Html.LabelFor(m =&gt; m.ContribType) &lt;/div&gt; &lt;div class="editor-field"&gt; @Html.DropDownListFor(m =&gt; m.ContribTypeOptions.First().ContribId, new SelectList(Model.ContribTypeOptions, "ContribId", "Value")) &lt;/div&gt; </code></pre> <p>When I submit the form the <code>ContribType</code> is (of course) null. </p> <p>What is the correct way to do this?</p>

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.
