willson asked 2 weeks ago

I want to have an ItemsControl in which the items are displayed horizontally.

However, no matter if I use StackPanel with Orientation=”Horizontal” or WrapPanel, they still stack up.

How can I get items in an ItemsControl to be horizontally?

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>

Code-Behind:

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; }
    }
}
