   App app1 = (App)Application.Current;
   app1.selcditempage(new page2());

and in page2 i have written as

List<string> newlist2 = new List<string>();
             
  foreach (var item1 in new MainPage().newlist) 
             {
               newlist2.Add(item1);
             }
             ndg.ItemsSource = newlist2;
