Remarks
The SqlDataSource data source control represents data in a SQL-based relational database to data-bound controls. You can use the SqlDataSource control in conjunction with a data-bound control to retrieve data from a relational database and display, edit, and sort data on a Web page with little or no code.
For more information on using the SqlDataSource control, see SqlDataSource Web Server Control.
Example
The following code example demonstrates how to declaratively use a SqlDataSource control to retrieve data from Microsoft SQL Server and display it in a GridView control.
