    Hi tuan,

    You may override the ToString() method in your Country class:

    public class Country
            public string Code{get;set;}
            public string Name{get;set;}
            public override string ToString()
                return this.Name;

    Thus the editor will not return the whole object, but rather the corresponding value for the Name property.
