radio button and datetime picker in silverlight 3 with c#

In XAML:


       
                                            
                        

And in the entity class:

public bool MGender
        {
            get
            {
                return _MGender;
            }
            set
            {
                _MGender = value;
            }
        }
        private bool _FGender;
        public bool FGender
        {
            get
            {
                return _FGender;
            }
            set
            {
                _FGender = value;
            }
        } 

In the WebService  :

while (rd.Read())
            {
                empObj = new Emp_Entity();//Initialise the entity
                empObj.EmpId = int.Parse(rd["EmpId"].ToString());              
                string gender = rd["EmpGender"].ToString();
                if (gender == "Male")
                {
                    empObj.MGender = true;
                    empObj.FGender = false;
                }
                if (gender == "Female")
                {
                    empObj.MGender = false;
                    empObj.FGender = true;
                }
                lstObj.Add(empObj); //add it to a list
            }
            return lstObj;
