WPF MenuItem:如何将SubMenuItem命令绑定到其父MenuItem

我已经制作了一个快速的原型,下面的绑定应该可以按照您的预期工作:

<DataTemplate DataType="{x:Type commmon:BuildConfiguration}">
    <TextBlock x:Name="ConfigBlock">
        <Run Text="{Binding Name, Mode=OneWay}"/>
        <TextBlock.InputBindings>
            <MouseBinding MouseAction="LeftClick" 
                          Command="{Binding DataContext.BuildCommand, 
                          RelativeSource={RelativeSource AncestorLevel=2, 
                          AncestorType={x:Type MenuItem}}}">
            </MouseBinding>
        </TextBlock.InputBindings>
    </TextBlock>
</DataTemplate>
