Ho creato un user control per testare la mia conoscenza.
Il problema che sorge è che quando in una pagina, inserisco più chiamate allo stesso user control, non funziona bene. Ad esempio:
se clicco sul bottone del primo user control dichiarato e seleziono una scelta, il dato viene evidenziato nel secondo user control dichiarato.
Per rendere l'idea, allego i due file sorgenti.
