Call a static C++/CLI method from C++

In a C++CLI project I make a call to a native object on an event, I'd like to be able to call a C++/CLI function from the native C++ when this event is triggered. I have following code at the moment, but it returns the error that PickObjects() is not a member of ManagedClass. Is calling back to a static C++CLI method possible?

#pragma once
#include "Stdafx.h"
#include "ManagedClass.h"

namespace Unmanaged
{
    public class EventHandlers
    {
    public:
        static void OnClick(customObject* caller, void *calldata)
        {
            //call managed method, can get here from CLI
            ManagedClass::ManagedObject::PickObjects();
        }
    };
}

Here is the C++CLI code snippet, everything here appears to run fine:

namespace ManagedClass
{
    public ref class ManagedObject  
    {
    public:
         static void PickObjects()
         {
         //pick stuff when called
         }
    };
}

EDIT: Got it working, the error was definitely related to how Visual Studio compiled the files. Will update with solution momentarily. Thanks to Matthias for the help.

It seems as though the classes were not getting compiled in the correct order. Adding the EventHandlers class to the end of ManagedClass got things working.

namespace ManagedClass
{
    public ref class ManagedObject  
    {
    public:
         static void PickObjects()
         {
         //pick stuff when called
         }
    };
    public class EventHandlers
    {
    public:
        static void OnClick(customObject* caller, void *calldata)
        {
            ManagedClass::ManagedObject::PickObjects();
        }
    };
}

Yes, calling a static method out of another static method is possible. In this case it sounds like you haven't declared ManagedClass::PickObjects() properly. You may show us the code (header should be enough) of it.
