tutto si può fare, dipende da quello che si vuole. :master:
Solo a titolo di esempio ti riporto un esempio del classico "regioni-province" fatto in tutte le salse, compreso ajax.
Utilizzo c# e il GridView per allenamento mio personale, ma non ci dovrebbero essere differenza significative col DataGrid.
