CollectionView 를 이용해 다양한 기능을 처리할수 있습니다.

여기선 데이터 정렬하는 기능을 알아봅니다.

 

먼저 데이터로 사용할 Class 를 정의합니다.

 

Person.cs

 

using System.ComponentModel;

 

namespace WpfApp

{

    public class Person : INotifyPropertyChanged

    {

        /// <summary>

        /// 속성변경 이벤트입니다.

        /// </summary>

        public event PropertyChangedEventHandler PropertyChanged;

 

        /// <summary>

        /// 이름입니다.

        /// </summary>

        string name = "";

 

        /// <summary>

        /// 별명입니다.

        /// </summary>

        string nickName = "";

 

        /// <summary>

        /// 이름입니다.

        /// </summary>

        public string Name

        {

            set

            {

                this.name = value;

                OnPropertyChanged(nameof(Name));

            }

            get { return name; }

        }

 

        /// <summary>

        /// 별명입니다.

        /// </summary>

        public string NickName

        {

            set

            {

                nickName = value;

                OnPropertyChanged(nameof(NickName));

            }

            get { return nickName; }

        }

 

        /// <summary>

        /// 속성 값이 변경될 때 발생합니다.

        /// </summary>

        /// <param name="propertyName"></param>

        protected virtual void OnPropertyChanged(string propertyName)

        {

            if (PropertyChanged != null)

            {

                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));

            }

        }

    }

}

 

 

MainWindow.xaml

<Window x:Class="WpfApp.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

        mc:Ignorable="d"

        Title="MainWindow" Height="450" Width="800">

    <StackPanel>

        <ListBox Name="listbox" Width="300" Height="300" Margin="24">

            <ListBox.ItemTemplate>

                <DataTemplate>

                    <StackPanel Orientation="Horizontal">

                        <TextBlock Text="{Binding Name}" />

                        <TextBlock Text="      " />

                        <TextBlock Text="{Binding NickName}" />

                    </StackPanel>

                </DataTemplate>

            </ListBox.ItemTemplate>

        </ListBox>

    </StackPanel>

</Window>

 

 

MainWindow.xaml.cs

 

using System.Collections.ObjectModel;

using System.ComponentModel;

using System.Windows;

using System.Windows.Data;

 

namespace WpfApp

{

    public partial class MainWindow : Window

    {

        public MainWindow()

        {

            InitializeComponent();

 

            ObservableCollection<Person> datas = new ObservableCollection<Person>();

 

            datas.Add(new Person(){ Name = "Kang",  NickName = "Super" });

            datas.Add(new Person(){ Name = "An",    NickName = "Father" });

            datas.Add(new Person(){ Name = "Jang",  NickName = "Marvel" });

 

            ICollectionView collectionView = CollectionViewSource.GetDefaultView(datas);

 

            collectionView.SortDescriptions.Add(new SortDescription(nameof(Person.Name), ListSortDirection.Ascending));

 

            this.listbox.ItemsSource = collectionView;

        }

    }

}

 

 

위 코드에서 보듯이 CollectionView 의 SortDescriptions 를 사용하여 정렬기준을 줄수 있습니다.
