dynamic textbox name problem

[ Infinite Dreams @ 14.05.2004. 14:18 ] @

imam textboxove na aspx stranici i svi se zovu isto samo sto se iz baze uzima id i dodaje na ime txtText i dobijaju se imena textboxova... problem tu nastaje kada hocu da uzmem vrednost iz takvog textboxa... probao sam to da uradim i napocetku je radilo, ali sada nece... ono sto me zanima jeste da li ja mogu to na neki nacin da uradim, a da to nije submit forme posto ovo radim sa dugmetom slikom koju kada kliknes ides na tu istu stranu i uzimas Request.Form("txtText" & id_iz_baze), ali to nece da radi... ako imate neku ideju vise je nego dobro dosla....
