    <p>I have an issue with my app, ill try explain by example, I have a form, this form exist of several textboxes and dropdown lists. For reusability I merged 3 drop down lists into a partial view, this partial view i load with @Html.Action, this works ok, when i start the form i see everything appears as it should be, although I dont know why but those required drop down lists directly are shown with red start and said it is required fields.</p> <p>But when i fill everything in, and i select the values from the drop down lists, and i click on OK, the values from drop down lists are NULL.</p> <p>I think it will be more comprehendable with a code example:</p> <p>Main model:</p> <pre><code>public class FormModel { [Required] public string UserName { get; set; } [Required] [Display(Name = "Birthdate")] public DateTime? Birthdate { get; set; } //This is what i'm talking about, that is not being set, the location public Location Location { get; set; } } </code></pre> <p>Here is the location class, which is then passed to the partial view and normally i think should be set, it looks like this:</p> <pre><code>public class Location { [Required] [Display(Name = "Country")] public string CountryId { get; set; } [Required] [Display(Name = "Region")] public string RegionId { get; set; } [Required] [Display(Name = "City")] public string CityId { get; set; } } </code></pre> <p>Now we have a partial view for the location:</p> <pre><code>@model TestWebsite.Models.Location &lt;tr&gt; &lt;td class="editor-label"&gt; @Html.LabelFor(m =&gt; m.CountryId) &lt;/td&gt; &lt;td class="editor-field"&gt; @Html.DropDownListFor(m =&gt; m.CountryId, Model.Countries, "---select--", null) &lt;/td&gt; &lt;td&gt; @Html.ValidationMessageFor(m =&gt; m.CountryId) &lt;/td&gt; &lt;/tr&gt; &lt;!-- Region --&gt; &lt;tr&gt; &lt;td class="editor-label"&gt; @Html.LabelFor(m =&gt; m.RegionId) &lt;/td&gt; &lt;td class="editor-field"&gt; @Html.DropDownListFor(m =&gt; m.RegionId, Enumerable.Empty&lt;SelectListItem&gt;(), "---select--", null) &lt;/td&gt; &lt;td&gt; @Html.ValidationMessageFor(m =&gt; m.RegionId) &lt;/td&gt; &lt;/tr&gt; &lt;!-- City --&gt; &lt;tr&gt; &lt;td class="editor-label"&gt; @Html.LabelFor(m =&gt; m.CityId) &lt;/td&gt; &lt;td class="editor-field"&gt; @Html.DropDownListFor(m =&gt; m.CityId, Enumerable.Empty&lt;SelectListItem&gt;(), "---select--", null) &lt;/td&gt; &lt;td&gt; @Html.ValidationMessageFor(m =&gt; m.CityId) &lt;/td&gt; &lt;/tr&gt; </code></pre> <p>Then we call this partial view in the forms like this:</p> <pre><code>@Html.Action("LocationGroup", "Account", Model.Location) </code></pre> <p>And finally in the controller:</p> <pre><code> [ChildActionOnly] public ActionResult LocationGroup(Location model) { model.Countries = GetCountries(); return PartialView("_LocationView", model); } </code></pre> <p>I know it is a lot of code, but i hope you could help me ...</p>

    1. CO**But when i fill everything in, and i select the values from the drop down lists, and i click on OK, the values from drop down lists are NULL.** Did you try submitting the forms with `JQuery/JSON` or did you try to set the the form contents by wrapping `Ajax.Begin` ?

    2. COCould you check the names of the properties that are sent to the server (via Firebug, for example) I bet that the names corresponding to your partial view doesnt fit the model in the name form. So mvc cannot to the binding.

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.

SQuiL has stopped working due to an internal error.

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