<p>Example from MVC 4 for dropdownlist validation on Submit using Dataannotation and ViewBag (less line of code)</p> <p>Models:</p> <pre><code>namespace Project.Models { public class EmployeeReferral : Person { public int EmployeeReferralId { get; set; } //Company District //List [Required(ErrorMessage = "Required.")] [Display(Name = "Employee District:")] public int? DistrictId { get; set; } public virtual District District { get; set; } } namespace Project.Models { public class District { public int? DistrictId { get; set; } [Display(Name = "Employee District:")] public string DistrictName { get; set; } } } </code></pre> <p>EmployeeReferral Controller:</p> <pre><code>namespace Project.Controllers { public class EmployeeReferralController : Controller { private ProjDbContext db = new ProjDbContext(); // // GET: /EmployeeReferral/ public ActionResult Index() { return View(); } public ActionResult Create() { ViewBag.Districts = db.Districts; return View(); } </code></pre> <p>View:</p> <pre><code><td> <div class="editor-label"> @Html.LabelFor(model => model.DistrictId, "District") </div> </td> <td> <div class="editor-field"> @*@Html.DropDownList("DistrictId", "----Select ---")*@ @Html.DropDownListFor(model => model.DistrictId, new SelectList(ViewBag.Districts, "DistrictId", "DistrictName"), "--- Select ---") @Html.ValidationMessageFor(model => model.DistrictId) </div> </td> </code></pre> <p>Why can't we use ViewBag for populating dropdownlists that can be validated with Annotations. It is less lines of code.</p>

Guidance

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.
