In this tutorial you will learn DetailView DataBound Control, To create a file system Web site, Connecting to SQL Server, Use a Drop-Down List as the Master and To test the drop-down list.

The DetailsView is a control that is complementary to the GridView control. It has been introduced in ASP.NET 2.0 to provide an ability to work with a single record or row from an associated data source. The default view of this control is vertical with each column of the record displayed on a line of its own. It is used for updating and inserting new records and used often in the Master-details scenario where the details of the record selected in the master is displayed in detail.

The DetailsView, like the GridView rides on the data source capabilities to update, insert or delete rows. It renders a single data item at a time even when the data source exposes more items. If the data object represents the ICollection interface or the underlying data source exposes the paging operation, the DetailsView can page over the data, provided the AllowPaging property is set to true. Users can also navigate between rows of data using this control.

The process of binding the DetailsView control to a data source is very simple. The DataSourceID property can be set declaratively or programmatically.
