Recall that to support inserting, updating, and deleting, with the Object Data Source we needed to specify the object layer methods to invoke to perform the insert, update, or delete action.
With the Sql Data Source, we need to provide SQL statements (or stored procedures) to execute.
To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.
One thing you'll learn about developing webpages is that its like petting a porcupine (yikes).
If you go with the flow, you probably won't get stuck, but the moment you try to go against the grain you end up with a hand full of thorns.
In previous tutorials we learned how the Object Data Source control allowed for inserting, updating, and deleting of data.
The Sql Data Source control supports the same operations, but the approach is different, and this tutorial shows how to configure the Sql Data Source to insert, update, and delete data.
