A unidirectional dataset can only move through records in one direction, not back and forward. A grid can move in both directions and so can't be connected to a unidirectional dataset.
You realy need to read the "Developers Guide", part II, 'Developing Database Applications', page 14-6.
To use a grid you need these components ...
SQLQuery
DataSetProvider
ClientDataSet
DataSource
DBGrid
This can also be achieved by using the TSQLClientDatSet which murges the first 3 components in the above list into 1.
