Pour lier les données entre les deux listboxes font référence aux éléments sélectionnés dans une zone de liste à l'autre listobx en utilisant le code XAML suivant:
Note: Je suis liaison à un ObservableCollection en utilisant un ViewModel; J'ai inclus la plupart de mon code ci-dessous pour permettre la reconstruction de ce code si nécessaire.

Voici le ViewModel qui inclut le code pour initialiser les collections:
public class MainViewModel : ViewModelBase
{
public MainViewModel()
{
{
TestContainer tc1 = new TestContainer();
tc1.ContainerName = "Container 1";
TestEntry te1 = new TestEntry();
te1.EntryName = "Search for Names";
tc1.TestEntries.Add(te1);
TestEntry te2 = new TestEntry();
te2.EntryName = "Search for People";
tc1.TestEntries.Add(te2);
TestEntry te3 = new TestEntry();
te3.EntryName = "Search for Things";
tc1.TestEntries.Add(te3);
_testContainers.Add(tc1);
}
{
TestContainer tc2 = new TestContainer();
tc2.ContainerName = "Container 2";
TestEntry te1 = new TestEntry();
te1.EntryName = "Look for Names";
tc2.TestEntries.Add(te1);
TestEntry te2 = new TestEntry();
te2.EntryName = "Look for People";
tc2.TestEntries.Add(te2);
TestEntry te3 = new TestEntry();
te3.EntryName = "Look for Things";
tc2.TestEntries.Add(te3);
_testContainers.Add(tc2);
}
{
TestContainer tc3 = new TestContainer();
tc3.ContainerName = "Container 3";
TestEntry te1 = new TestEntry();
te1.EntryName = "Find Names";
tc3.TestEntries.Add(te1);
TestEntry te2 = new TestEntry();
te2.EntryName = "Find People";
tc3.TestEntries.Add(te2);
TestEntry te3 = new TestEntry();
te3.EntryName = "Fine Things";
tc3.TestEntries.Add(te3);
_testContainers.Add(tc3);
}
}
private ObservableCollection<TestContainer> _testContainers = new ObservableCollection<TestContainer>();
public ObservableCollection<TestContainer> TestContainers
{
get
{
return _testContainers;
}
set
{
_testContainers = value;
}
}
}
Voici TestContainer:
public class TestContainer
{
public string ContainerName { get; set; }
private ObservableCollection<TestEntry> _testEntries = new ObservableCollection<TestEntry>();
public ObservableCollection<TestEntry> TestEntries
{
get
{
return _testEntries;
}
set
{
_testEntries = value;
}
}
}
Voici TestEntry:
public class TestEntry
{
public string EntryName { get; set; }
}
ici la vue où e J'initialise le ViewModel:
public partial class MainView : Window
{
public MainView()
{
InitializeComponent();
this.DataContext = new ViewModels.MainViewModel();
}
}
