    <p>I am trying to edit a record. The Controller code is:</p> <pre><code> public ActionResult EditFixture(int id) { RLSBCWebSiteDb _context = new RLSBCWebSiteDb(); Fixture fixture = _context.Fixtures.Find( id ); ViewData["Gender"] = new SelectList( Fixture.GetGenderList(""), "Value", "Text", fixture.Gender ); ViewData["MatchTypeList"] = new SelectList( Fixture.GetMatchTypeList( "" ), "Value", "Text", fixture.MatchType ); ViewData["TeamNameList"] = new SelectList( Fixture.GetTeamNameList( "" ), "Value", "Text", fixture.TeamName ); ViewData["CommentsList"] = new SelectList( Fixture.GetCommentsList( "" ), "Value", "Text", fixture.Comments ); return View( fixture ); } [HttpPost] public ActionResult EditFixture( Fixture fixture ) { ViewData["Gender"] = new SelectList( Fixture.GetGenderList( "" ), "Value", "Text", fixture.Gender ); ViewData["MatchTypeList"] = new SelectList( Fixture.GetMatchTypeList( "" ), "Value", "Text", fixture.MatchType ); ViewData["TeamNameList"] = new SelectList( Fixture.GetTeamNameList( "" ), "Value", "Text", fixture.TeamName ); ViewData["CommentsList"] = new SelectList( Fixture.GetCommentsList( "" ), "Value", "Text", fixture.Comments ); if (ModelState.IsValid) { rlsbcWebSite.Fixtures.Add( fixture ); rlsbcWebSite.SaveChanges(); return RedirectToAction( "DisplayFixtures", new { id = fixture.MatchDate.Year.ToString() } ); } return View( fixture ); } </code></pre> <p>The view code is as follows:</p> <pre><code>&lt;%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage&lt;RLSBCWebSite.Domain.Entities.Fixture&gt;" %&gt; &lt;asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"&gt; UpdateFixture &lt;/asp:Content&gt; &lt;asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"&gt; &lt;h1&gt;Update the Fixture&lt;/h1&gt; &lt;% using (Html.BeginForm()) { %&gt; &lt;%: Html.ValidationSummary(true) %&gt; &lt;fieldset&gt; &lt;legend&gt;Fixture&lt;/legend&gt; &lt;%: Html.HiddenFor(model =&gt; model.FixtureID) %&gt; &lt;%: Html.Partial("CreateOrEditFixture") %&gt; &lt;p&gt; &lt;input type="submit" value="Save" /&gt; &lt;/p&gt; &lt;/fieldset&gt; &lt;% } %&gt; &lt;div class="grid_2"&gt; &lt;%: Html.ActionLink("Back to List", "Index") %&gt; &lt;br /&gt;&lt;br /&gt; &lt;/div&gt; &lt;/asp:Content&gt; &lt;asp:Content ID="Content3" ContentPlaceHolderID="scriptContent" runat="server"&gt; &lt;/asp:Content&gt; </code></pre> <p>The code for the partial is as follows:</p> <pre><code>&lt;%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl&lt;RLSBCWebSite.Domain.Entities.Fixture&gt;" %&gt; &lt;%: Html.LabelFor(model =&gt; model.Gender) %&gt; &lt;%: Html.DropDownListFor( model =&gt; model.Gender, (ViewData["GenderList"] as SelectList) ) %&gt; &lt;%: Html.ValidationMessageFor(model =&gt; model.Gender) %&gt; &lt;%: Html.LabelFor(model =&gt; model.MatchType) %&gt; &lt;%: Html.DropDownListFor( model =&gt; model.MatchType, (ViewData["MatchTypeList"] as SelectList) )%&gt; &lt;%: Html.ValidationMessageFor(model =&gt; model.MatchType) %&gt; &lt;%: Html.LabelFor(model =&gt; model.TeamName) %&gt; &lt;%: Html.DropDownListFor( model =&gt; model.TeamName, (ViewData["TeamNameList"] as SelectList) )%&gt; &lt;%: Html.ValidationMessageFor(model =&gt; model.TeamName) %&gt; &lt;%: Html.LabelFor(model =&gt; model.MatchDate) %&gt; &lt;%: Html.TextBox( "MatchDate", Model.MatchDate.ToShortDateString() )%&gt; &lt;%: Html.ValidationMessageFor(model =&gt; model.MatchDate) %&gt; &lt;%: Html.LabelFor(model =&gt; model.Opponents) %&gt; &lt;%: Html.EditorFor(model =&gt; model.Opponents) %&gt; &lt;%: Html.ValidationMessageFor(model =&gt; model.Opponents) %&gt; &lt;%: Html.LabelFor(model =&gt; model.Venue) %&gt; &lt;%: Html.EditorFor(model =&gt; model.Venue) %&gt; &lt;%: Html.ValidationMessageFor(model =&gt; model.Venue) %&gt; &lt;%: Html.LabelFor(model =&gt; model.StartTime) %&gt; &lt;%: Html.EditorFor(model =&gt; model.StartTime) %&gt; &lt;%: Html.ValidationMessageFor(model =&gt; model.StartTime) %&gt; &lt;%: Html.LabelFor(model =&gt; model.ScoreFor) %&gt; &lt;%: Html.EditorFor(model =&gt; model.ScoreFor) %&gt; &lt;%: Html.ValidationMessageFor(model =&gt; model.ScoreFor) %&gt; &lt;%: Html.LabelFor(model =&gt; model.ScoreAgainst) %&gt; &lt;%: Html.EditorFor(model =&gt; model.ScoreAgainst) %&gt; &lt;%: Html.ValidationMessageFor(model =&gt; model.ScoreAgainst) %&gt; &lt;%: Html.LabelFor(model =&gt; model.Comments) %&gt; &lt;%: Html.DropDownListFor( model =&gt; model.Comments, (ViewData["CommentsList"] as SelectList) )%&gt; &lt;%: Html.ValidationMessageFor(model =&gt; model.Comments) %&gt; </code></pre> <p>The <code>&lt;div&gt;</code>s have been removed in the above.</p> <p>The call to edit the record displays the data OK including the correct choice for the dropdown lists. I make a few changes and the select the <code>Save</code> button. The correct POST event is called but the <code>Fixture fixture</code> parameter is null. ModelState is not valid and returns an error message of </p> <pre><code>The parameter conversion from type 'System.String' to type 'RLSBCWebSite.Domain.Entities.Fixture' failed because no type converter can convert between these types. </code></pre> <p>Why is fixture of type Fixture not being passed back correctly.</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.
