listview绑定到wpf类的对象

Question

I have the following AddedInfo class:

public class AddedInfo : ViewModelBase
{
    private string m_infoString = "ppp";
    private ToggleButton m_infoButton = new ToggleButton();

    #region Properties

    public string InfoString
    {
        get { return m_infoString; }
        set
        {
            m_infoString = value;
            OnPropertyChanged();
        }
    }
    public ToggleButton InfoButton
    {
        get { return m_infoButton; }
        set
        {
            m_infoButton = value;
            OnPropertyChanged();
        }
    }

    #endregion Properties
}

In my ViewModel , I have the following definition:

private ObservableCollection<AddedInfo> m_informationList = new ObservableCollection<AddedInfo>();

public ObservableCollection<AddedInfo> InformationList
{
    get { return m_informationList; }
    set
    {
        m_informationList = value;
        OnPropertyChanged();
    }
}

And in the Xaml :

<ListView Grid.Row="1" Background="Black" ItemsSource="{Binding InformationList, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" 
                      HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch"/>

I would like the ListView to show only the ToggleButtons from class AddedInfo (meaning the InfoButton object).

Can such thing be done?

You should use ItemTemplate for the ListView. You did not provide details about the ToggleButton class, but it should not be a control. In MVVM the viewmodels and models should contain only data. The control can be rendered in the view using DataTemplates (as ItemTemplate contains a DataTemplate).
