barra navigazione recordset

alessandromonti · 24 Mag 2012

salve
realizzando sito ... nel database ho tabella "riservata" formata campi id, nome,cognome,sesso,e-mail,username,password,livello..con un form faccio ricerca tramite il nome e voglio limitare il numero di recordset visibili alla volta, ad esempio 1, e con una barra di navigazione siano visibili gli altri recordset.
Il problema: a seguito della ricerca è visibile solo il primo recordset (oppure i primi 2 o 3 o 4 in base al limite impostato)... la barra di navigazione non mi fa vedere gli altri ...risponde come se la ricerca non avesse rilevato altri recordset...se imposto di vedere tutti i recordset trovati la pagina dei risultati della ricerca mi evidenzia tutti i recordset caricati nella tabella.
suggerimenti?
grazie
