MVC model boolean display yes or no

In your view:

@(item.isTrue?"Yes":"No")

You could use a custom html helper extension method like this:

@Html.YesNo(item.IsTrue)

Here is the code for this:

public static MvcHtmlString YesNo(this HtmlHelper htmlHelper, bool yesNo)
{
    var text = yesNo ? "Yes" : "No";
    return new MvcHtmlString(text);
}

This way you could re-use it throughout the site with a single line of Razor code.
