Data-bound Web server controls are controls that can be bound to a data source control to make it easy to display and modify data in your Web application. Data-bound Web server controls are composite controls that combine other ASP.NET Web controls, such as Label and TextBox controls, into a single layout.

For example, a data-bound control such as a DetailsView control can bind to a set of results such as a table of employees containing each employee's name, address, job title, and so on. Within the DetailsView control, you can bind Label controls to a single data values such as the name or address field to create the data layout in the page.

In addition to enabling you to bind the control to a set of data results, data-bound controls enable you to customize the layout of the control using templates. They also provide a convenient model for handling and canceling events.
