Global notify if object has saved

Hi!
This is probably offtopic but.

I'm using CAB on building the project, but now in the situation when in one form data will be saved. I want to notify another databound form, to reload the latest data.

For this reason I thought that static event will do the trick in BusinessBase object.

so. I have one static event, but there is no difference witch object is saved it will notify oll subscribers not the special Business object.

OrderBO.OnSave+=new EventHandler(OnReloadOrderData);
CustomerBO.OnSave+=new EventHandler(OnReloadCustomerData);

Does anyone have an idea how bound static event to only the specific class that inherits the BusinessBase object?

CSLA version 2.1 has the ISavable interface, which should raises a Saved event for each object that is saved, giving your event handler access to both the original and new objects.

If you want, you could create a static observer that handles these events (in your objects' DP_XYZ and OnDeserialized events you'd hook the instance events to the static observer). This static observer could then raise a global event. Make sure your EventArgs subclass includes both the original and new object references.

Appreciate if you can provide some simple code. Thanks
