Hello,

I am working on an Add-In where I need to wire up events for IActiveViewEvents_Event.ItemAdded and IActiveViewEvents_Event.ItemDeleted. Basically I need to way to execute my code when a layer is added/deleted.

I have tried:
 
m_activeViewEventsEvent = ArcMap.Document.FocusMap as IActiveViewEvents_Event;
m_activeViewEventsEvent.ItemDeleted += new IActiveViewEvents_ItemDeletedEventHandler(m_activeViewEventsEvent_ItemDeleted);
m_activeViewEventsEvent.ItemAdded += new IActiveViewEvents_ItemAddedEventHandler(m_activeViewEventsEvent_ItemAdded);


But the events never fire. This code used to work just fine in 9.3. Has something change in 10.0? Any help will be appreciated.

Thanks,

Sebastian,

No this isn't working. This is actually what I am doing in my code.

hey

in the snippet this is done:

  // Create an instance of the delegate, add it to ItemAdded event
  m_ActiveViewEventsItemAdded = new ESRI.ArcGIS.Carto.IActiveViewEvents_ItemAddedEventHandler(OnActiveViewEventsItemAdded);
  activeViewEvents.ItemAdded += m_ActiveViewEventsItemAdded;


that differs from what you have posted. Unless you variable "m_activeViewEventsEvent_ItemAdded" is like:
m_activeViewEventsEvent_ItemAdded = OnActiveViewEventsItemAdded;

But "OnActiveViewEventsItemAdded" is a method, the method handler and not a variable. So this method is called when the event is fired.
I do not know if you're working with delegates on "m_activeViewEventsEvent_ItemAdded".

This seem to work for another user (quick google search within first 5 hits):

Sebastian,

m_activeViewEventsEvent_ItemAdded is not a variable - its a method. Sorry I should rename the method to just activeViewEventsEvent_ItemAdded - sorry dealing with some legacy code here. I will try out the other links. I really appreciate your help.

thanks,
