You can get collection of selected items: list.SelectedItems. Each item you can cast to CheckedListItem and check that item is checked. If you want to handle property changing, you should implement interface INotifyPropertyChanged in CheckedListItem class

Example of INotifyPropertyChanged: Add this to your class and call OnPropertyChanged in properties:

    private boolean _isChecked;
    public boolean IsChecked
    {
        get { return _isChecked; }
        set
        {
            _isChecked= value;
            OnPropertyChanged("IsChecked");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected void OnPropertyChanged(string name)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            handler(this, new PropertyChangedEventArgs(name));
        }
    }
