Domanda

Voglio creare un'opzione pulsante che prende l'intero datalist e lo converte in un file pdf. Come qualcuno ha fatto questo in asp.net? Per favore, puoi mostrare un esempio o indirizzarmi nel modo giusto.

È stato utile?

Ho appena trovato uno snippet di codice pubblicato da un ragazzo nel forum e, sebbene potrei condividerlo con altri

Altri suggerimenti

Puoi provare a sviluppare la tua soluzione usando PDFSharp una libreria pdf molto semplice per .net

Puoi provare this e modifica il tipo di contenuto in PDF.

Questo ha funzionato benissimo, non mi dà margini nonostante ciò che ho impostato sul sito. Esiste un modo per farlo per la parte Word di questo? Inoltre trovo che la parte PDF non funzioni.
