I Designed My Silverlight XMAL Page With AutoComplete Box,Search Button And Data Grid.
Now I Wrote Wcf Service With LinqToSql For getting Related Data from DataBase Table When I Entered Data In AutoComplete Box And Clicked On Search Button then result will be displayed in DataGrid In SilverLight.

For Above Requirement I Wrote Code Like Below:

first i wrote class with properties like,

public class University
   {        public string PUnivId {set;get;}
       public string PUnivName{set;get;}
       public string PUnivAdd{set;get;}
       public string PAICTEgrd{set;get;}
   }

Wcf Service Code:

public class Service1
    {
       [OperationContract]
        public List<University> UniversityList(string sdata)
        {
            var UnivList = new List<University>();
            SwathiClsDataContext obj = new SwathiClsDataContext();
            var s = from i in obj.fg0uv000s.AsEnumerable() where i.UnivID == sdata select i;
         if(s!=null)
            foreach(var dt in s)
            {
                var univ = new University
                {
                    PUnivId=dt.UnivID.ToString(),
                    PUnivName=dt.UnivName.ToString(),
                    PUnivAdd=dt.UnivAdd.ToString(),
                    PAICTEgrd=dt.AICTEgrd.ToString()
                };
               UnivList.Add(univ);
            }
            return UnivList;
        }
    }

After adding wcf service reference in silverlight application,i wrote code using eventhandler like this,

private void btnSearch_Click(object sender, RoutedEventArgs e)
 {
  ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
  client.UniversityListCompleted+=new EventHandler<UniversityListCompletedEventArgs>(client_UniversityListCompleted);
            client.UniversityListAsync(txtAcb.Text);
}
    void client_UniversityListCompleted(object sender, UniversityListCompletedEventArgs e)
    {
            mydatagrid.ItemsSource = e.Result;
   }

my complete code is above,but i didn't get result into datagrid.

Please give me some suggestions to get result.
