    <p>I have a Masterpage (site.master) that calls a View using RenderAction. At the moment the View returns "hello world". </p> <p>site.master:</p> <pre><code>&lt;%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %&gt; &lt;html&gt; &lt;head id="Head1" runat="server"&gt; &lt;title&gt;&lt;asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server" /&gt;&lt;/title&gt; &lt;asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server" /&gt; &lt;/head&gt; &lt;body&gt; &lt;% Html.RenderAction("Test", "Charts"); %&gt; &lt;asp:ContentPlaceHolder ID="ContentPlaceHolder3" runat="server" &gt; &lt;p&gt;site.master&lt;/p&gt; &lt;/asp:ContentPlaceHolder&gt; &lt;asp:ContentPlaceHolder ID="ContentPlaceHolder4" runat="server" /&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>Test.aspx:</p> <pre><code>&lt;%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage&lt;dynamic&gt;" %&gt; hello world! </code></pre> <p>ChartsController.cs:</p> <pre><code>public ActionResult Test() { return View(); } </code></pre> <p>If I update the View to pass in the name of the Masterpage explicitly I get an error when I call RenderAction.</p> <p>ChartsController.cs:</p> <pre><code>public ActionResult Test() { return View(null, "site"); } </code></pre> <p>Error:</p> <p>Content controls have to be top-level controls in a content page or a nested master page that references a master page.</p> <pre><code>Stack Trace: [HttpException (0x80004005): Content controls have to be top-level controls in a content page or a nested master page that references a master page.] System.Web.UI.MasterPage.CreateMaster(TemplateControl owner, HttpContext context, VirtualPath masterPageFile, IDictionary contentTemplateCollection) +8857854 System.Web.UI.Page.get_Master() +54 System.Web.UI.Page.ApplyMasterPage() +15 System.Web.UI.Page.PerformPreInit() +45 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +328 </code></pre> <p>How do I go about setting the master page that I want the view to use? Ultimately I will be setting the Masterpage dynamically using a custom ViewEngine (by overriding VirtualPathProviderViewEngine.FindView).</p> <pre><code>if ( String.IsNullOrEmpty(masterName) ){ masterName = "site"; } </code></pre> <p>When I set the masterName property in my ViewEngine and then call RenderAction from site.master I get the same error as when I set the masterName property in the Action.</p> <p>I am using:<br> Visual Studio 2010<br> MVC 3<br> IIS Express </p> <p>edited: added full site.master markup</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.

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