How to get a UIHint attribute value from an MVC Razor view

The UIHint Attribute is a great way to pass metadata from a model to a view. I was looking around for a simple way to get the value of the attribute from my razor view. I could be missing something obvious, but I couldn’t find anything. Brad Wilson has some great posts about ModelMetadata if you want to look at in more depth.

You set UIHint Attributes in your model like this:

[DataMember]
[UIHint("Hidden")]
public string Key { get; set; }

You could write a custom ModelMetadata provider and so on to get it or you can do what I did and write a simple extension method on PropertyInfo to grab the data. I will expand on the design later, but it meets my needs right now.

public static class PropertyInfoExtensions
{
public static bool IsHidden(this PropertyInfo property)
{
return string.Compare(ModelMetadataProviders.
Current.GetMetadataForProperty(null, property.DeclaringType,
property.Name).TemplateHint, "Hidden") == 0;
}
}

And then in your view you just call IsHidden

@foreach (var prop in Model.GetType().GetProperties())
{
<td>
if(!prop.IsHidden())
{
@prop.GetValue(Model, null)
}
</td>
}
