Examples

The following example creates a ListBox, which inherits from ItemsControl, and binds it to a collection of Customer objects. The example sets the DisplayMemberPathProperty to the LastName property of the customer. Therefore, the ListBox displays the following values:

Anderberg
Ashton
Hicks
Pica

<Grid>
    <Grid.Resources>
        <src:Customers x:Key="customers"/>
    </Grid.Resources>
    <ListBox ItemsSource="{StaticResource customers}" Width="250" Margin="0,5,0,10" 
       DisplayMemberPath="LastName"/>
</Grid>

The following example shows the Customer class and the collection that the ListBox is bound to.

Public Class Customer
    Private _firstName As String
    Private _lastName As String
    Private _address As String

    Public Property FirstName() As String
        Get
            Return _firstName
        End Get

        Set(ByVal value As String)
            _firstName = value
        End Set
    End Property

    Public Property LastName() As String
        Get
            Return _lastName
        End Get

        Set(ByVal value As String)
            _lastName = value
        End Set
    End Property

    Public Property Address() As String
        Get
            Return _address
        End Get

        Set(ByVal value As String)
            _address = value
        End Set
    End Property

    Public Sub New(ByVal firstName As String, ByVal lastName As String, ByVal address As String)
        Me.FirstName = firstName
        Me.LastName = lastName
        Me.Address = address
    End Sub

End Class

Public Class Customers
    Inherits ObservableCollection(Of Customer)

    Public Sub New()
        Add(New Customer("Michael", "Anderberg", "12 North Third Street, Apartment 45"))
        Add(New Customer("Chris", "Ashton", "34 West Fifth Street, Apartment 67"))
        Add(New Customer("Cassie", "Hicks", "56 East Seventh Street, Apartment 89"))
        Add(New Customer("Guido", "Pica", "78 South Ninth Street, Apartment 10"))
    End Sub

End Class

public class Customer
{
    public String FirstName { get; set; }
    public String LastName { get; set; }
    public String Address { get; set; }

    public Customer(String firstName, String lastName, String address)
    {
        this.FirstName = firstName;
        this.LastName = lastName;
        this.Address = address;
    }

}

public class Customers : ObservableCollection<Customer>
{
    public Customers()
    {
        Add(new Customer("Michael", "Anderberg",
                "12 North Third Street, Apartment 45"));
        Add(new Customer("Chris", "Ashton",
                "34 West Fifth Street, Apartment 67"));
        Add(new Customer("Cassie", "Hicks",
                "56 East Seventh Street, Apartment 89"));
        Add(new Customer("Guido", "Pica",
                "78 South Ninth Street, Apartment 10"));
