Sorry about that. I've been doing so much control development lately I'm too used to such events being CancelEventHandler events (or similar)!

Yes, you'll have to throw the exception so add a handler to AppDomain.UnhandledException like I mentioned before. I recommend you also create a custom exception class that derives from ApplicationException (typically used for custom exceptions to give them a common, application-based base class) that you throw from the DataTable.RowChanging event handler. This way, you can easily just catch this exception in the handler for the AppDomain.UnhandledException event and handle appropriately, which is better than throwing such a oft-used exception and trying to determine where it came from and why it was thrown.
