Answer / vaidyanathan r.

Dataset is a collection of Datatables along with their
relations. Dataset is the copy of part/full of the actual
data base stored in the application during execution for
data manipulations.

And there is no equivalent methods to previous and next
methods of ADO as each table is treated as a seperate
objects inside the Dataset. However a particular record can
be retrieved by the "Rows" property of the Data Table.

Eg: DataRow dr = DataSet1.Tables[<TableIndex>].Rows
[<RowIndex>]

how can implement dropdownlist in particular of dataset when try to update?
