The IBX package includes TDBControlGrid - a lookalike rather than a clone for the Delphi TDBCrtlGrid. While distributed as part of IBX, it is not dependent on use of Firebird or IBX and can be used with any database that works with the TDataSet model.
TDBControlGrid does not place any restrictions on the controls that can be used with it, unlike the Deplhi TDBCtrlGrid which demands that they are "replicable". It is also cross-platform.
