ADO.NET --> Dataset...

[Khanh Duy]

I like using Dataset ...but there's a question in my mind that if you use dataset to modify your data in the table(example: Customers) and another user's using dataset to modify data on the table too...then what happend if another user deleted some row ,change primary key and SAVE to the database .... your data is now not the same to the database .......Can you explain me about DISCONECTED DATA...advantage and disadvantage..thanks you....I hope you understand my question ...(my English is not good).. The man with nothing to lose

You can read about Optimistic Concurrency in the MSDN library which describes the scenario that you are referring to .
