                                </i:EventTrigger>
                            </i:Interaction.Triggers>
                        </ListBox>
 

其中、需要在程式碼

 <i:InvokeCommandAction Command="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type local:Control_CodeAutoGeneration}}, Path=DataContext.RelayCommand}"   CommandParameter="ClassSelectionChanged"/>

處繫結的父級別，Control_CodeAutoGeneration是我自定義的控制元件的ViewModel裡面的RelayCommand命令，通過如上傳遞可以呼叫到父級別的ViewModel的繫結屬性或命令
