Hi, thanks for answering.
I have to process the data from the database and place it in a
datatable in order to do it.
In brief I'm doing something like this:

1) Read the data from SQL and put it in a datatabel (dt_aux).
2) Process dt_aux and place it into dt with this line
  dt=filtra_activas(dt_aux.Copy());
3) Assign the dt to the datagridview every time, since otherwise it
doesn't notice wether the dt have changed.

So I cannot bind directly the datagridview with the SQL.

Any other idea? (or maybe go further on the explanation on this one if
I've got it wrong)
