Hi MF,
GridDataBoundGrid doesn''t have built in support for associating selected rows with the underlying DataRows whereas GridGroupingControl has this feature.
To get this in GDBG, you can try this approach. Before the rows are added in the DataTable, you can store the PrimaryKeys of the selected rows in a datastore. After the new rows are added, you can re-select the rows that has these unique primary keys.
Here is a sample.
Best regards,
Jay
