listview与ObservableCollection之间的动态更新

当listview绑定到一个observablecollection时，如果collection中的值更新时，listview并没有刷新。这个collection需要实现INotifyPropertyChanged接口。

如下:

    <StackPanel>

        <ListView Width="600" Height="400"

                  ItemsSource="{Binding Source={StaticResource Customers}}">

            <ListView.View>

                <GridView>

                    <GridViewColumn Width="100" Header="Customer ID"

                                    DisplayMemberBinding="{Binding Id}"/>

                    <GridViewColumn Width="100" Header="Customer Name"

                                    DisplayMemberBinding="{Binding Name}"/>

                </GridView>

            </ListView.View>

        </ListView>

    </StackPanel>

</Window>

public class Customer : INotifyPropertyChanged

{

    private string id, name;

    public string Id

    {

        get { return this.id; }

        set

        {

            if (value != this.id)

            {

                this.id = value;

                OnPropertyChanged(new PropertyChangedEventArgs("Id"));

            }

        }

    }

    public string Name

    {

        get { return this.name; }

        set

        {

            if (value != this.name)

            {

                OnPropertyChanged(new PropertyChangedEventArgs("Name"));

            }

        }

    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(PropertyChangedEventArgs e)

    {

        if (this.PropertyChanged != null) this.PropertyChanged(this, e);

    }

}

public class CustomerCollection : ObservableCollection<Customer>

{

    public CustomerCollection()

    {

        this.Add(new Customer() { Id = "C-111", Name = "Mike" });

        this.Add(new Customer() { Id = "C-222", Name = "Bigger" });

        this.Add(new Customer() { Id = "C-333", Name = "Pop" });

    }

}
