Using Html.DisplayFor() outside of view or getting formatted property from DisplayFormat annotation
c#,asp.net,asp.net-mvc,razor,data-annotations
You can use a generic type for the method: public static string GetProductSnippet<T>(Product product, HtmlHelper<T> helper) { return helper.DisplayFor(p => p.ReleaseDate).ToString(); } var markup = GetProductSnippet<List<Product>>(product, helper); As for getting the code without the helper, you can get the implementation of the display helper from MVC source code and adjust...

Remote validation doesn't work when property to validate is inside a modal Bootstrap
