Is there a way to get the value of an annotation in server side code? For example, I have:

You will need to use reflection. Here is a sample console program that does what you want.

class Program
{
    static void Main(string[] args)
    {
        Dummy dummy = new Dummy();
        PropertyInfo[] properties = dummy.GetType().GetProperties();
        foreach (PropertyInfo property in properties)
        {
            IEnumerable displayAttributes = property.GetCustomAttributes(typeof(DisplayAttribute), false).Cast();
            foreach (DisplayAttribute displayAttribute in displayAttributes)
            {
                Console.WriteLine("Property {0} has display name {1}", property.Name, displayAttribute.Name);
            }
        }
        Console.ReadLine();
    }
}

public class Dummy
{
    [Display(Name = "Foo")]
    public string foo { get; set; }

    [Display(Name = "Bar")]
    public string bar { get; set; }
}

This would produce the following result:
