How to Display HTML with MVC’s NullDisplayText Attribute

Adding DisplayFormat attribute to model’s property allows you to set formatting options for that property’s value. One of options is NullDisplayText, where you can set what to display if the value is null.

Sometimes you may wish to have NullDisplayText return a piece of HTML. To be able to render this HTML correctly, you need to set HtmlEncode value to false.

[DisplayFormat(NullDisplayText = "<div>My HTML<div>", HtmlEncode = false)]
public int? MyProperty { get; set; }
