The DataRow class
represents a single row of data in the DataTable.
The DataRow class can retrieve, update, insert,
and delete a row of data from the DataTable. Using
the DataRow class, each column value for the row
can be accessed.
The DataRow maintains the
RowState
property that is used by ADO.NET to
track the changes that have been made to a
DataRow. This property allows changed rows to be
identified, and the appropriate update command to be used to update
the data source with the changes.
