               client.GetGridDetailCompleted += new EventHandler<GetGridDetailCompletedEventArgs>(client_GetGridDetailCompleted);
               client.SolutionCompleted += new EventHandler<SolutionCompletedEventArgs>(client_SolutionCompleted);
               this.solution = new ObservableCollection<SolutionData>();
               this.customers = new ObservableCollection<displaydata>();
               this.Gridobjects = new ObservableCollection<GridData>();
               client.TypeSolutionCompleted += new EventHandler<TypeSolutionCompletedEventArgs>(client_TypeSolutionCompleted);
           }
           public void client_TypeSolutionCompleted(object o, TypeSolutionCompletedEventArgs e)
           {
               if (e.Error == null && e.Result != null)
               {
                   foreach (displaydata c in e.Result)
