The following table details the possible values of the Data Row State enumeration: The row has been created but is not part of any Data Row Collection.A Data Row object is in this state immediately after it has been created, before it has been added to a collection, and after it has been removed from a collection. The Data Row Version fields are used when retrieving the value found in a Data Row using the Item[String, Data Row Version] property or the Get Child Rows method of the Data Row object.If you do send the changes back to the database, a second step is required.
If you're familiar with Table Adapters, you can jump directly to one of these topics: Updating a data source is a two-step process.The original version of a record is a copy of the record as it was the last time changes were committed in the dataset.In practical terms, this is typically the version of a record as read from a data source.You can prevent a concurrency violation by filling another dataset with the updated records from the data source and then performing a merge to prevent a concurrency violation.(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.
