Ragazzi non riesco a visualizzare la textbox associata alla GridView nell'EditItemTemplate...Questo è il codice....Una spiegazione veloce..la tabella si chiama Categorie (Id, Nome e in Tipo ci sono gli elementi totali) il binding lo faccio da dll...sul binding non ci sono problemi perchè l'ho controllato e funziona perfettamente...il problema è il GridRowEditing a cui ho riassociato il binding del pageload pensando che non fosse valorizzato il bind<nome> della textbox2

<%@ Page Language="C#" MasterPageFile="~/Default.master" Title="Your Name Here | Admin"
