Is there a way to get an @Html.DisplayFor value to show "NULL" in the view if the value of the model item is null?

Here's an example of an item in my Details view that I'm working on currently. Right now if displays nothing if the value of the Description is null.

<div class="display-field">
    @Html.DisplayFor(model => model.Description)
</div>

yes, I would recommend using the following data annotation with a nullable datetime field in your codefirst model :

[Display(Name = "Last connection")]
[DisplayFormat(NullDisplayText = "Never connected")]
public DateTime? last_connection { get; set; }

then in your view :

@Html.DisplayFor(x => x.last_connection)
