SQL data source control: This control enables you to connect to and bind
data to a number of underlying data sources, that is, Microsoft SQL Server,
OLEDB, ODBC or Oracle databases.
Access data source control: This control can be used to bind data to
Microsoft Access databases.
Xml data source control: This control can be used to bind data to XML data
sources, that is, external XML data files, dataset instances, etc.
With these data source controls, you can easily implement data driven ASP.NET
applications without the need to write the data access code. The only thing you have
to do is, add and configure a data source control in your web page and then associate
the DataSourceID property of any web control in your web page to the ID property
of the data source control in use. The web control would now display the data using
the data source control that you have used in your web page. You are done!
In the sections that follow, we would explore how you can use each of these controls
to bind data to your controls seamlessly.
The Object Data Source Control
The Object data source control, one of the new data source controls added in ASP.
NET 2.0, can be used to de-couple the User Interface or the Presentation Layer of the
application from the Business Logic and the Data Access Layers.
