Perché gli articoli nel mio layout ItemsControls non sono orizzontali?

Question

Desidero avere un comando Items in cui vengono visualizzati gli articoli in orizzontale.

Tuttavia, non importa se uso StackPanel con Orientamento = "Orizzontale" o WrapPanel, ancora accumulano.

Come è possibile ottenere elementi in un ItemsControl in modo che siano orizzontali?

XAML:

<Window x:Class="TestItemsControl2938.Window1" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     Title="Window1" Height="300" Width="400"> 
    <Window.Resources> 
     <DataTemplate x:Key="CustomerListTemplate"> 
      <StackPanel Width="100" Background="#aaa" Margin="5"> 
       <TextBlock Text="{Binding LastName}"/> 
      </StackPanel> 
     </DataTemplate> 
    </Window.Resources>  
    <StackPanel> 
     <StackPanel Orientation="Horizontal" Background="Orange"> 
      <ItemsControl ItemsSource="{Binding CustomerList}" ItemTemplate="{StaticResource CustomerListTemplate}"/> 
     </StackPanel> 
     <WrapPanel Background="Yellow"> 
      <ItemsControl ItemsSource="{Binding CustomerList}" ItemTemplate="{StaticResource CustomerListTemplate}"/> 
     </WrapPanel> 
    </StackPanel> 
</Window> 

codice sottostante:

using System.Windows; 
using System.ComponentModel; 
using System.Collections.ObjectModel; 
namespace TestItemsControl2938 
{ 
    public partial class Window1 : Window, INotifyPropertyChanged 
    { 
     private ObservableCollection<Customer> _customerList = new ObservableCollection<Customer>(); 
     public ObservableCollection<Customer> CustomerList 
     { 
      get{ return _customerList; }  
      set 
      { 
       _customerList = value; 
       OnPropertyChanged("CustomerList"); 
      } 
     } 

     public Window1() 
     { 
      InitializeComponent(); 
      DataContext = this; 

      CustomerList.Add(new Customer { FirstName = "Jim", LastName = "Jones" }); 
      CustomerList.Add(new Customer { FirstName = "Joe", LastName = "Adams" }); 
      CustomerList.Add(new Customer { FirstName = "Jake", LastName = "Johnson" }); 
     } 


     public event PropertyChangedEventHandler PropertyChanged; 

     protected void OnPropertyChanged(string propertyName) 
     { 
      PropertyChangedEventHandler handler = PropertyChanged; 

      if (handler != null) 
      { 
       handler(this, new PropertyChangedEventArgs(propertyName)); 
      } 
     } 
    } 

    public class Customer 
    { 
     public string FirstName { get; set; } 
     public string LastName { get; set; } 
     public string Street { get; set; } 
     public string Location { get; set; } 
     public string ZipCode { get; set; } 
    } 
} 

Answer 1

modo sbagliato. Personalizza il pannello che ItemsControl utilizza per contenere i suoi articoli:

<ItemsControl> 
    <ItemsControl.ItemsPanel> 
     <ItemsPanelTemplate> 
      <StackPanel Orientation="Horizontal"/> 
     </ItemsPanelTemplate> 
    </ItemsControl.ItemsPanel> 
</ItemsControl> 

Answer 2

è necessario utilizzare il pannello degli articoli. guarda here la mia risposta
