c# - Caliburn.micro and devexpress: insert tabs (dockpanel) from viewmodel when user clicks -

cheers all,

i'm searching use devexpress tool in visual c# project (vs2013). i'm using caliburn.micro , i've inserted caliburn.micro.devexpress reference. so, environment.

the problem: want create container, can open predefined tabs. can navigate in open tabs, close them , open others.

i'm in stuck integration of devexpress , caliburn. without caliburn , without mvvm pattern, it's easy. how can using viewmodel?

the result want example "simple mdi" in [the official caliburn.micro documentation1]. instead of button "open tab", i've menu in upper side and, depending on button clicked, want open relative dockpanel/tab.

now, in xaml file, container devexpress object, "documentgroup". goal add dynamically documentpanel(s), written above.

is clear problem? ideas solution?

update: in viewmodel have:

namespace **.viewmodels { class mainwindowviewmodel : conductor<iscreen>.collection.oneactive {     public void addt() {         debug.writeline("start");         activateitem(new ucimpiantiviewmodel());         debug.writeline("end");     } } 

}

and in xaml have:

... <dxd:documentgroup x:name="items" itemheight="3*" selectedtabindex="0"> ... 

i thought way good, still nothing.. new console.writeline working!
