I have created a helper method like this:

public static string GetDisplayName(this HtmlHelper html, Expression> property)
{
    return GetDisplay(property);
}

public static string GetDisplayName(this HtmlHelper> html, Expression> property)
{
    return GetDisplay(property);
}

private static string GetDisplay(Expression> property)
{
    var propertyExp = (MemberExpression)property.Body;
    var member = propertyExp.Member;
    var disp = (DisplayAttribute)member.GetCustomAttribute(typeof(DisplayAttribute));
    if (disp == null)
    {
        return member.Name;
    }
    return disp.Name;
}

And used it like this:

new WebGridColumn { Header = Html.GetDisplayName(t=>t.Title), ColumnName = nameof(DataModel.Title), CanSort=true }
