    <p>While trying to find how to get this working I came across a blog post that said neither Description nor Watermark are usable with the present incarnation of the DataAnnotations framework.</p> <p>I came up with a workaround that looks roughly like this:</p> <p>(Disclaimer: this code is edited from my compiling version to remove it from a metadata provider built through composition so it may not compile directly without some touchups.)</p> <pre><code>public class CustomDataAnnotationsModelMetadataProvider : DataAnnotationsModelMetadataProvider { protected override ModelMetadata CreateMetadata(IEnumerable&lt;System.Attribute&gt; attributes, System.Type containerType, System.Func&lt;object&gt; modelAccessor, System.Type modelType, string propertyName) { var baseModelMetadata = base.CreateMetadata(attributes, containerType, modelAccessor, modelType, propertyName); var result = new CustomMetadata(modelMetadataProvider, containerType, modelAccessor, modelType, propertyName, attributes.OfType&lt;DisplayColumnAttribute&gt;().FirstOrDefault(), attributes) { TemplateHint = !string.IsNullOrEmpty(templateName) ? templateName : baseModelMetaData.TemplateHint, HideSurroundingHtml = baseModelMetaData.HideSurroundingHtml, DataTypeName = baseModelMetaData.DataTypeName, IsReadOnly = baseModelMetaData.IsReadOnly, NullDisplayText = baseModelMetaData.NullDisplayText, DisplayFormatString = baseModelMetaData.DisplayFormatString, ConvertEmptyStringToNull = baseModelMetaData.ConvertEmptyStringToNull, EditFormatString = baseModelMetaData.EditFormatString, ShowForDisplay = baseModelMetaData.ShowForDisplay, ShowForEdit = baseModelMetaData.ShowForEdit, DisplayName = baseModelMetaData.DisplayName }; return result; } } public class CustomMetadata : DataAnnotationsModelMetadata { private string _description; public CustomMetadata(DataAnnotationsModelMetadataProvider provider, Type containerType, Func&lt;object&gt; modelAccessor, Type modelType, string propertyName, DisplayColumnAttribute displayColumnAttribute, IEnumerable&lt;Attribute&gt; attributes) : base(provider, containerType, modelAccessor, modelType, propertyName, displayColumnAttribute) { var descAttr = attributes.OfType&lt;DescriptionAttribute&gt;().SingleOrDefault(); _description = descAttr != null ? descAttr.Description : ""; } // here's the really important part public override string Description { get { return _description; } set { _description = value; } } } </code></pre> <p>Then in your Global.asax in Application_Start or wherever you register your model metadata providers:</p> <pre><code>ModelMetadataProviders.Current = new CustomMetadataProvider(); </code></pre>

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).
