Sto provando a utilizzare il controllo AsyncFileUpload dall'Asp.net Ajax Control Toolkit (30/900 stabile stabile del 30 settembre 2009: 30930). Ho creato un'applicazione demo e il controllo funziona correttamente. Il caricamento dei file e tutto va bene.Asp.Net Ajax Toolkit AsyncFileUpload - "Il file è allegato non valido" errore
Quando si tenta di utilizzare il controllo nella mia applicazione reale, viene sempre visualizzato un messaggio di errore "Il file allegato non è valido". Il controllo AsyncFileUpload restituisce questo quando il file caricato è nullo.
Per isolare il problema, ho creato una nuova pagina master esattamente come la pagina principale nella mia app demo. Ho anche creato una pagina di aspx esattamente come la pagina nella mia app demo. Il caricamento non riesce ancora con un errore "Il file allegato non è valido".
Ho anche confrontato il web.config per l'app reale e l'app demo e non sono stato in grado di identificare eventuali differenze che dovrebbero essere importanti.
Il codice seguente è il codice di prova nella mia app reale. Questo codice è esattamente lo stesso del codice funzionante nell'app demo, con l'eccezione di avere nomi di classi e nomi di file diversi. Il web.config elencato di seguito proviene dall'app reale con le impostazioni e le connessioni rimosse.
A questo punto, sono completamente perplesso.

Modifica: non sto più lavorando per questa azienda, quindi non posso testare nuove risposte per vedere se risolvono il problema.
Ran il campione con un web.config di default, jQuery 1.4.1 e 3.5 AjaxControlToolkit .50731; cambiato la pagina master in un ToolkitScriptManager e ha funzionato bene. Ho ricevuto l'errore dopo essere passato al tuo web.config (creato anche cartelle App_Code \ CS | VBCode). – user423430
nella funzione startUpload (sender, args) { $ ('# uploadMessage p'). Html(); $ ('# uploadMessage'). Hide(); } $ ('# uploadMessage p'). Html(); non fa nulla Restituirebbe l'html a una variabile o qualcosa del genere, ma se usato in questo modo non fa nulla, credo. Vuoi eliminare l'html esistente? $ ('# uploadMessage p'). html ('') o $ ('# uploadMessage p'). empty(); Dubito che questo sia il problema, ma comunque jQuery non è usato correttamente. – Hcabnettek
