    <p>You can't use embedded razor strings within the lambda expression, as @Alessandro D'Andra suggests you have to use <code>x =&gt; "&lt;img src='" + someString + "'&gt;&lt;/img&gt;";</code> instead.</p> <p>You might also have to wrap it all in an <code>MvcHtmlString</code> to prevent Razor from escaping the string once it is used by the formatter, but I don't know exactly how the formatter works - you have to try it.</p> <p>I made a small test file to find out exactly what the Razor compiler would do with your code. This is the razor file:</p> <pre><code>@{ string someString = "somestring"; Func&lt;object, object&gt; a = x =&gt; "&lt;text&gt;&lt;img src='" + someString + "'&gt;&lt;/img&gt;&lt;/text&gt;"; Func&lt;object, object&gt; b = x =&gt; @&lt;text&gt;&lt;img src="@someString"&gt;&lt;/img&gt;&lt;/text&gt;); } </code></pre> <p>The ASP.NET compiler creates this C# code out of it (only relevant parts included):</p> <pre><code> string someString = "somestring"; Func&lt;object, object&gt; a = x =&gt; "&lt;text&gt;&lt;img src='" + someString + "'&gt;&lt;/img&gt;&lt;/text&gt;"; Func&lt;object, object&gt; b = x =&gt; #line default #line hidden item =&gt; new System.Web.WebPages.HelperResult(__razor_template_writer =&gt; { BeginContext(__razor_template_writer, "~/Views/Home/Index.cshtml", 210, 4, true); WriteLiteralTo(__razor_template_writer, "&lt;img"); EndContext(__razor_template_writer, "~/Views/Home/Index.cshtml", 210, 4, true); WriteAttributeTo(__razor_template_writer, "src", Tuple.Create(" src=\"", 214), Tuple.Create("\"", 231) #line 7 "c:\temp\MvcApplication1\Views\Home\Index.cshtml" , Tuple.Create(Tuple.Create("", 220), Tuple.Create&lt;System.Object, System.Int32&gt;(someString #line default #line hidden , 220), false) ); BeginContext(__razor_template_writer, "~/Views/Home/Index.cshtml", 232, 7, true); WriteLiteralTo(__razor_template_writer, "&gt;&lt;/img&gt;"); EndContext(__razor_template_writer, "~/Views/Home/Index.cshtml", 232, 7, true); </code></pre> <p>Using the embedded text syntax <code>@&lt;text&gt;</code> within the lambda expression creates obviously incorrect C# code. It is not smart enough to make the embedded tags part of the lambda expression, instead it breaks the lambda expression by inserting code to emit the embedded text right away.</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.
