        }
    }
}

En faite lorsqu'on clique sur Button1 un CrystalReport doit étre affiché, le code source de cette page "CR_imprim.aspx" est le suivant:

            }
            return ds.Tables[0];
        }
 
    }
}

mais le problème que je peux pas utiliser le composant "cr3" de "WF_chrch_VT.aspx" dans "CR_imprim.aspx" pour afficher
le TextBox! qu'est ce que je dois faire pour utiliser "cr3" au lieu de "rptDoc" comme ReportSource pour "CR_imprim.aspx"
Merci d'avance
