    <p>You can use expressions for this. The usage would look like this:</p> <pre><code>Magic_GetName&lt;Foo&gt;(x =&gt; x.Bar) </code></pre> <p>The implementation of <code>Magic_GetName</code> would look like this:</p> <pre><code>public static string Magic_GetName&lt;TClass&gt;( Expression&lt;Func&lt;TClass, object&gt;&gt; propertyExpression) { propertyExpression.Dump(); var body = propertyExpression.Body as UnaryExpression; if (body == null) { throw new ArgumentException( string.Format( CultureInfo.InvariantCulture, "The body of the 'propertyExpression' should be an " + "unary expression, but it is a {0}", propertyExpression.Body.GetType())); } var memberExpression = body.Operand as MemberExpression; if (memberExpression == null) { throw new ArgumentException( string.Format( CultureInfo.InvariantCulture, "The operand of the body of 'propertyExpression' should " + "be a member expression, but it is a {0}", propertyExpression.Body.GetType())); } var propertyInfo = memberExpression.Member as PropertyInfo; if (propertyInfo == null) { throw new ArgumentException( string.Format( CultureInfo.InvariantCulture, "The member used in the expression should be a property, " + "but it is a {0}", memberExpression.Member.GetType())); } return propertyInfo.Name; } </code></pre> <p><strong>Update:</strong> The title of this question is "Getting property names at <strong>compile</strong> time".<br> My answer actually doesn't do that. The method <code>Magic_GetName</code> is executed at <em>runtime</em> and as such has a performance impact.</p> <p>The .NET 4.5 way using <a href="http://danrigby.com/2012/03/01/inotifypropertychanged-the-net-4-5-way/" rel="noreferrer">the <code>CallerMemberName</code> attribute</a> on the other hand is really <a href="http://rohiton.net/2012/03/05/caller-information/" rel="noreferrer">a compile time feature</a> and as such doesn't have a runtime impact. However, as I already said in the comments, it is not applicable in the given scenario.</p>

    1. COThanks, that'd do the job. I wish the usage would look better though...

    2. CO@Jonathan: The following usages would be possible, too: (1) `Magic_GetName(() => new Foo().Bar)` (2) `Magic_GetName<Foo>(x => x.Bar)`

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).
