menu dynamic

My Menu is perfectly bound with observable collection in view model and all submenu items fires click event properly using below xaml, but I am unable to set the same click event for first menu items. Is it possible to set same click event on all primary menu items? <Menu Background="Lavender"...

Would I use blend or something else? Are there useful online tutorials I can look at? I’ve currently developed a winform app and I want to change it to use a dynamically generated menu. I want it to generate menu options based on queries for key words. Thanks.
