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.
