how can i generate dynamic menus

 

i wanna create menus at run-time...

 

but i cannot insert a item to any menu item as a child item... because the items is not a xtpControlPopup item...

 

i add the menu item as xtpControlButton... because i dont know these items will be xtpControlPopup control has child-item(s)... maybe it has no child-item(s). but when the code is running any item can be child-item for a menu-item...

 

i get error when i try to add a child-item to that item (xtpControlButton).
