Not updating table adapter

This allows you to maximize the performance of your ADO. For example, if a primary key value for an existing row is updated, and a new row has been added with the new primary key value as a foreign key, it is important to process the update before the insert. By specifying a subset of rows to be updated, you can control the order in which inserts, updates, and deletes are processed.

NET application by specifying command syntax at design time and, where possible, through the use of stored procedures. For example, the following code ensures that the deleted rows of the table are processed first, then the updated rows, and then the inserted rows.

However, you can also use different adapters, for example, to move data from one data source to another or to update multiple data sources.

If you aren't using data binding, and are saving changes for related tables, you have to manually instantiate a variable of the auto-generated Table Adapter Manager class, and then call its Udpate All method.
