MapControl图层增加和图层删除事件

1.获取框架时，首先绑定MapControl的OnMapReplaced事件

 ((IMapControlEvents2_Event)MapControl).OnMapReplaced += new IMapControlEvents2_OnMapReplacedEventHandler(OnMapReplaced);     

2.绑定图层增加和图层删除事件

 public void LoadLayerEvent(object item)
 {
  IActiveViewEvents_Event pActiveViewEvent = (IActiveViewEvents_Event)MapControl.ActiveView;
  pActiveViewEvent.ItemDeleted += new IActiveViewEvents_ItemDeletedEventHandler(ItemChanged);
  pActiveViewEvent.ItemAdded += new IActiveViewEvents_ItemAddedEventHandler(ItemChanged);
 }

public void ItemChanged(object item)
{}
