Command Binding in hierarchical datatemplate

Question

I have Menu in my app. I\'m visualizing it using hierarchical data template:

Answer 1

Continue digging this problem. I've tried other way using ItemsContainer Style, described there link text, because DataTemplate creates MenuItem within another MenuItem, which is not pretty good and it also adds some artefacts to clicking behavior.

I've forgotten to mention that ApplicationMenu is an observable collection of my custom RMenuItem class. So this way also works, but commands don't work either!!! BUT I've noticed interesting feature - command binding don't works if we setting Menu's source via ItemsSource, if we add MenuItems statically (just uncommenting last line) - command binding defined in ItemContainerStyle works!!! -(( Why it happens so???? But it is not my ending aim - I'd like to make mechanism of building menu based on some collection with ability of assigning RoutedCommand (in order to have hot-key for menuitem). The situation is being complicated by using MVVM approach: my collection of menuitems resides in ViewModel layer, while RoutedCommands is a View's feature, while I'm using simple ICommands in my ViewModel. So there is a food for thought ... -))
