CXTPControlListBox message handle

How can i handle the CXTPControlListBox message ??

 

look at the code below...

 

 pToolBarLogInfo->GetControls()->Add(xtpControlLabel, 0)->SetCaption(_T("CXTPControlListBox:"));
 pPopupLogInfo = (CXTPControlPopup*)pToolBarLogInfo->GetControls()->Add(xtpControlPopup, 0);
 pPopupLogInfo->SetCaption(_T("ListBox"));
 pListBoxLogInfo= (CXTPControlListBox*)pPopupLogInfo->GetCommandBar()->GetControls()->Add(new CXTPControlListBox, 0);
 pListBoxLogInfo->GetListCtrl()->AddString(_T("Item 1"));
 pListBoxLogInfo->GetListCtrl()->AddString(_T("Item 2"));

 

then we can see the list item , Item1 , Item2 , how can i add a message handle to the Item1 and Item2 .

 

I mean , if I click the Item1 ,the function1 will be called ,

if  I click the Item2 ,the function2 will be called ,

How can I do that ,someboby give me help,please!
