    <p>You use <code>&lt;% ... %&gt;</code> to evaluate some JavaScript in an Underscore template but you use <code>&lt;%= ... %&gt;</code> if you want the output to end up in the result; from the <a href="http://underscorejs.org/#template" rel="nofollow">fine manual</a>:</p> <blockquote> <p>Template functions can both interpolate variables, using <code>&lt;%= … %&gt;</code>, as well as execute arbitrary JavaScript code, with <code>&lt;% … %&gt;</code>.</p> </blockquote> <p>You're looking to interpolate the <code>imgId</code> value into the result so you want this:</p> <pre><code>&lt;img src= "@Url.Content("+&lt;%= imgId %&gt;+")" alt="Assigned Details" /&gt; </code></pre> <p>Simplified Demo: <a href="http://jsfiddle.net/ambiguous/9gyKC/" rel="nofollow">http://jsfiddle.net/ambiguous/9gyKC/</a></p> <p>Presumably <code>@Url.Content</code> is something that gets run on the server to produce a <code>src</code> attribute for a given resource. If that's the case then you'll have to rethink how this works; the <code>&lt;%= ... %&gt;</code> stuff happens in the browser <em>after</em> <code>@Url.Content</code> has been executed so it will be too late when the Underscore template runs. Your note about an <code>imgId</code> error with this:</p> <pre><code>&lt;img src= "&lt;%= @Url.Content(string.Format("~/Content/Images/{0}", imgId)) %&gt;" /&gt; </code></pre> <p>supports this theory. Your server code doesn't know what <code>imgId</code> is, only the client-side JavaScript does.</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.

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).
