    <p>So i'm building a simple mvc4 application, I have created all base models for the creation of the DB, from these classes I could naturally create basic controllers with their matching views.<br><br> Now my problem: I have the basic create actionresult + view and in this view I wanted that the user would be able to select some values from a dropdownlist which would make creation of new objects simpler.<br><br> I tried to achieve this with a second form in my view (the first one is the basic create form) now if I want to use these dropdowns (they filter each other(so first the user must specify a continent, then the dropdown of the countries only shows countries from that continent and after he specifies a country the region dropdown gets updated :) )) the submit of the basic view is always automatically called.</p> <p>so making the dropdowns update themselves isn't the problem :s it's that the form for the create automatically validates when the dropdowns are updated</p> <p>this is the controller where the dropdowns filter each other</p> <pre><code>// // GET: /FederationCenter/Create public ActionResult Create(string searchRegion, string searchCountry, string searchContinent) { var countries = from c in db.Countries select c; if (!String.IsNullOrEmpty(searchContinent)) { Continent searchContinentEnumValue = (Continent)Enum.Parse(typeof(Continent), searchContinent); countries = from c in db.Countries where ((int)c.Continent).Equals((int)searchContinentEnumValue) select c; } var regions = from r in db.Regions where r.Country.Name.Equals(searchCountry) select r; ViewBag.searchContinent = new SelectList(Enum.GetNames(typeof(SchoolCup.Domain.Continent))); ViewBag.searchCountry = new SelectList(countries, "Name", "Name"); ViewBag.searchRegion = new SelectList(regions, "Name", "Name"); return View(); } // // POST: /FederationCenter/Create [HttpPost] [ValidateAntiForgeryToken] public ActionResult Create(NSSF nssf, string searchRegion, string searchCountry, string searchContinent) { var countries = from c in db.Countries select c; if (!String.IsNullOrEmpty(searchContinent)) { Continent searchContinentEnumValue = (Continent)Enum.Parse(typeof(Continent), searchContinent); countries = from c in db.Countries where ((int)c.Continent).Equals((int)searchContinentEnumValue) select c; } var regions = from r in db.Regions where r.Country.Name.Equals(searchCountry) select r; ViewBag.searchContinent = new SelectList(Enum.GetNames(typeof(SchoolCup.Domain.Continent))); ViewBag.searchCountry = new SelectList(countries, "Name", "Name"); ViewBag.searchRegion = new SelectList(regions, "Name", "Name"); if (ModelState.IsValid) { var naam = Request["searchRegion"]; Region creatie = (from c in db.Regions where c.Name.Equals(naam) select c).SingleOrDefault(); nssf.ISFId = 1; nssf.RegionId = creatie.RegionId; db.NSSFs.Add(nssf); db.SaveChanges(); return RedirectToAction("Index"); } return View(nssf); } </code></pre> <p>and this is my view</p> <pre><code>@model SchoolCup.Domain.POCO.NSSF @{ ViewBag.Title = "Create"; } &lt;h2&gt;Create NSSF&lt;/h2&gt; &lt;div&gt; @using (Html.BeginForm(null, null, FormMethod.Post, new { name = "form" })) { @Html.AntiForgeryToken() @Html.DropDownList("searchContinent", null, "-- All continents --", new { onchange = "sendForm()" }) @Html.DropDownList("searchCountry", null, "-- All countries --", new { onchange = "sendForm()" }) @Html.DropDownList("searchRegion", null, "-- All regions --", new { onchange = "sendForm()" }) &lt;&gt; &lt;input type="submit" name= value="Search" /&gt; } &lt;/div&gt; @using (Html.BeginForm()) { @Html.AntiForgeryToken() @Html.ValidationSummary(true) &lt;fieldset&gt; &lt;legend&gt;NSSF&lt;/legend&gt; &lt;div class="editor-label"&gt; @Html.LabelFor(model =&gt; model.Name) &lt;/div&gt; &lt;div class="editor-field"&gt; @Html.EditorFor(model =&gt; model.Name) @Html.ValidationMessageFor(model =&gt; model.Name) &lt;/div&gt; </code></pre> <p>some more inputs</p> <pre><code> &lt;/fieldset&gt; &lt;p&gt; &lt;input type="submit" value="Create" /&gt; @Html.ActionLink("Back to List", "Index", null, new { @class = "button" }) &lt;/p&gt; } @section Scripts { &lt;script type="text/javascript"&gt; function sendForm() { document.form.submit() } &lt;/script&gt; } </code></pre> <p>I've been looking for at least a day and I don't know how to solve this</p> <p>with regards Alexander</p>

    1. COYour question is not clear but it is almost clear. ;) I think if you expand this sentence with more information: `now if I want to use these dropdowns (they filter each other) the submit of the basic view is always automatically called.` then your question will become clear to everyone.

    3. COPerhaps this post will help you: http://stackoverflow.com/questions/5497524/easiest-way-to-create-a-cascade-dropdown-in-asp-net-mvc-3-with-c-sharp. The answer uses AJAX to fetch new options as a JSON response then replace the select items.

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).
