The original version of a record is a copy of the record as it was the last time changes were committed in the dataset.(A concurrency violation occurs when another user modifies a record in the data source after the dataset has been filled.) To make changes to an existing data row, add or update data in the individual columns.If the dataset contains constraints (such as foreign keys or non-nullable constraints), it's possible that the record can temporarily be in an error state as you update it.If you aren't using data-bound controls, you have to manually call the method of the same Table Adapter (or data adapter) that you used to populate the dataset.
However, you can also use different adapters, for example, to move data from one data source to another or to update multiple data sources.After you complete an update, you can re-enable constraint checking, which also re-enables update events and raises them.
