Question

I have a problem with my Binding to a ListBox Control.
Actually i have a Property in App.xaml.cs :

public partial class App : Application, INotifyPropertyChanged
{
    ObservableCollection<Panier> _panier = new ObservableCollection<Panier>();

    public ObservableCollection<Panier> PanierProperty
    {
        get { return _panier; }
        set
        {
            if (this._panier != value)
            {
                this._panier = value;
                NotifyPropertyChanged("PanierProperty");
            }
        }
    }
    public event PropertyChangedEventHandler PropertyChanged;

    protected void NotifyPropertyChanged(String property)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(property));
        }
    }
}

this property have a child properties in the “Panier class” here:

public class Panier : INotifyPropertyChanged
{
    private string _nom;
    private string _category;
    private int _prix;

    public string Nom
    {
        get { return _nom; }
        set
        {
            if (this._nom != value)
            {
                this._nom = value;
                NotifyPropertyChanged("Nom");
            }
        }
    }

    public string Category
    {
        get { return _category; }
        set
        {
            if (this._category != value)
            {
                this._category = value;
                NotifyPropertyChanged("Category");
            }
        }
    }

    public int Prix
    {
        get { return _prix; }
        set
        {
            if (this._prix != value)
            {
                this._prix = value;
                NotifyPropertyChanged("Prix");
            }
        }
    }
    public event PropertyChangedEventHandler PropertyChanged;

    protected void NotifyPropertyChanged(String property)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(property));
        }
    }
}

and in my MainWindow.xaml page i have my ListBox bound to PanierProperty(parent property) :

<telerik:RadListBox x:Name="PanierLB" Grid.Row="1" Height="200" Width="350" Margin="0 300 0 0"
    ItemsSource="{Binding PanierProperty, Source={x:Static Application.Current}}"
    DisplayMemberPath="{Binding Path=PanierProperty.Nom, Source={x:Static Application.Current}}">
</telerik:RadListBox>

my problem is that PanierProperty is bound to my Listbox i see items in the listbox like Design.Panier
Design.Panier
Design.Panier
etc…
I dont know how to get the PanierProperty.Nom(Nom is the child property) to show on the ListBox.

Someone can help please.

In DisplayMemberPath use the name of property you want to show only:

<telerik:RadListBox
    ...
    DisplayMemberPath="Nom"
