i know can

<i:interaction.triggers>     <i:eventtrigger eventname="click">         <actions:closetabitemaction tabitem="{binding relativesource={relativesource ancestortype=tabitem}}"                                      tabcontrol="{binding relativesource={relativesource ancestortype=tabcontrol}}"/>     </i:eventtrigger> </i:interaction.triggers>

i've been through same menuitem on datatemplate.

what did add setter property=command inside style type button. here's code:

<datatemplate x:key="whatever"> <style targettype="menuitem">    <setter property="command" value="{binding comando}" />    <setter property="commandparameter" value="{binding texto}"/> </style> </hierarchicaldatatemplate.itemcontainerstyle> <stackpanel orientation="horizontal">     <!--<image source="{binding imagem}" />-->     <accesstext text="{binding texto}" /> </stackpanel> </datatemplate> 

remembering {binding comando} icommnd property of viewmodel this:

private icommand _comando; public icommand comando {         {         return _comando;     }     set     {         _comando = value;         onpropertychanged("comando");     } } 

at view set comando (icommand) wanted this:

viewmodel.menusubitem.add(new menuviewmodel { texto = "xxxxx", comando = whatevercommand }); 

hope helpful!
