This is exactly what I was looking for. I still have an issue with this approach. When I use RowFilter on the DataView derived from source DataTable, update/delete performed on the rows in DataView are affected on source DataTable. With the approach in the article, how can I achieve the same result i.e., update/delete on source DataTable. Any help would be very much appreciated. Excellent Article!

The code is like following: DataColumn[] keys = new DataColumn[3]; keys[0] = dtToExport.Columns[0]; keys[1] = dtToExport.Columns[1]; keys[2] = dtToExport.Columns[3]; dtToExport.PrimaryKey = keys; Just in case some need it but don’t know about that: adding a primary keys for datatable speed SELECT() very, very much (in my case: from 60 sec. without it to less than 1 sec. with it).
