How to manage delete operations on a Datagridview when binding with custom business objects?

I have implemented the INotifyPropertyChanged Interface for my class.
I am able to handle insert and update operations. But when a user deletes a row, as per .NET Architecture the ListChanged event gets fired after the value is deleted from the source object.

Now how do get to know that what row was deleted if I need to update the database based on delete operation?

Well.. maintaining another list and then comparing the can be a solution, but I think it would be a bad solution..
so.. any help is welcome..

Thanx.

The datagridview's UserDeletingRow event fires just before the row is deleted. I would get the info you need about the row in this event.
