+Summary: DataView generates redundant IBindingList Reset events
+
+Description of Problem:
+DataView's implementation of IBindingList incorrectly generates events 
+when items are added to/removed from the list; when an item is added, a 
+Reset event is generated and only then an ItemAdded event is generated.
+Same goes when removing an item - a Reset event is generated, followed by 
+an ItemDeleted event.
+
+I'll attach a demo app to illustrate this behaviour. The app was tested 
+on MS .Net; there, only the ItemAdded and ItemDeleted events are 
+generated.
+
+Steps to reproduce the problem:
+1. Compile the attached (below) file with a reference to System.Data.
+2. Run the application and watch the generated events (the app adds a row 
+and then removes a row).
+
+Actual Results:
+Reset events are generated before the ItemAdded and ItemRemoved events.
+
+Expected Results:
+Only ItemAdded and ItemRemoved events should be generated.
+
+How often does this happen? 
+All the time.
