如何根據用戶的選擇顯示特定數量的文本框？

Question

用戶可以從1-8位玩家中進行選擇，在下一頁我希望他爲每位玩家輸入名字。我怎樣才能使文本框取決於他們的選擇。 例如，他們選擇4，我想顯示四個文本框，以便他們可以放四個名字。

您將變量（玩家人數）過濾到下一頁。獲取變量後，只需將許多項目添加到您的收藏中。然後顯示你的收藏。

Page1.xaml.cs

// then you navigate like this (From Page1) 
int number_of_players = 4; 
Frame.Navigate(typeof(Page2), number_of_players); 

Page2.xaml.cs

int number_of_players = 0; 

// and in target Page you retrive the information: 
protected override void OnNavigatedTo(NavigationEventArgs e) 
{ 
    // get the number of players passed 
    number_of_players = e.Parameter as int; 
}  


// add in the correct number of players into the observable collection 
private void Page_Loaded(object sender, RoutedEventArgs e) 
{ 
    ObservableCollection<sample_model> my_list = new ObservableCollection<sample_model>(); 
    for (int i = 0; i < number_of_players; i++) 
    { 
     // where sample_model is a model of a player 
     my_list.Add(new sample_model("player name")); 
    } 

    this.myListView.ItemsSource = my_list; 
}
