Performing Bulk Copy Operations with the SqlBulkCopy Object
The SqlBulkCopy class provides a high-performance method for copying data to a table in a SQL Server database. The source of the copy is constrained to the overloads of the WriteToServer method, which can accept an array of DataRow objects, an object that implements the IDbDataReader interface, a DataTable object, or a DataTable and DataRowState, as shown in Figure 4-13. This variety of parameters means that you can retrieve data from most locations.
Creating a Templated User Control
A templated user control provides separation of control data from its presentation, meaning that a templated user control does not provide a default user interface. For example, if you know that you need to display your shipper's information, such as the shipper ID, the shipper name, and the shipper phone number, but you don't know how the page designer wants to format this information, you could create a templated user control called ShipperControl that allows the page designer to supply the...
