  private void appointment Rijhltsdetasncln Chenjed (object sender, select Chenjedaventargs e) {// Cynitivent Sileted = appointment selected as Rijltdetakcynitivent; If (Appointment Results) Selected Index == -1 returns; ListBoxItem currentSelectedListBoxItem = this. AppointmentResultsData.ItemContainerGenerator.ContainerFromIndex (AppointmentResultsData.SelectedIndex) as ListBoxItem; If return (currently selected LIBBOX == empty) return; // Replace the entire list tree again and search for this item. Text box namebox = helper class.andandsendant & lt; Text box & gt; (Currently selected listbox items); Text Block Name Block = Assistant Class. Find & lt; TextBlock & gt; (Currently selected listbox items); MessageBox.Show (nameBlock.Text + "" + nameBox.Text); }
