WPF MenuItem: How to bind a SubMenuItem command to to its Parent MenuItem

I want to Bind the e.g. "Debug|Any CPU" MenuItem Command which has its own BuildConfiguration Context to the Project Context BuildProjectCommand. How to do it correctly?

I already tried to accomplish this with FindAncestor but it won't work. e.g. Command="{Binding Path=DataContext.BuildCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type MenuItem}}}"

See picture for more understanding: enter image description here

Solution

  • I've made a quick prototype and binding below should work as you expect:

    <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>
