Perdre du fichier dans un fichier de contrôle de téléchargement dans le panneau de mise à jour c# asp.net

J'ai une page où je suis à l'aide de 3 mise à jour des panneaux et toutes les mise à jour des panneaux de bien travailler. Dans l'un des panneau de mise à jour j'ai un bouton qui sur cliquez sur les changements de texte de l'étiquette, mais le problème est que, si le post de retour qui se passe dans toute de la mise à jour des panneaux de téléchargement de fichiers perd de son fichier. Tout le panneau de mise à jour sont utilisés pour mettre à jour les différentes sections de la page. Pas de panneau de mise à jour est imbriqué. upload de fichier est à côté, c'est à dire, il n'est pas dans les panneau de mise à jour, mais il est de perdre son fichier. Je pense que le problème est tout à fait compréhensible et n'a pas besoin de code pour montrer. Grâce

Par défaut asp.net contrôle FileUpload ne fonctionnera jamais avec UpdatePanel. Vous avez besoin spécial AsyncFileUpload de contrôle tel que défini dans AjaxControl Toolkit.
```
`<ajaxToolkit:AsyncFileUpload OnClientUploadError="uploadError"
OnClientUploadComplete="uploadComplete" runat="server"
ID="AsyncFileUpload1" Width="400px" UploaderStyle="Modern"
UploadingBackColor="#CCFFFF" ThrobberID="myThrobber" />`
```
ou Vous pouvez utiliser le Panneau de mise à Jour des Déclencheurs

<Triggers> <asp:PostBackTrigger ControlID="YourControlID" /> </Triggers>

cela ne marche pas. rien ne se déclenche.

J'ai passé tout l'après-midi sur ce sujet aujourd'hui, à l'aide de n'importe quel nombre de solutions que j'ai trouvé sur différents forums, y compris celui-ci, CodeProject.com, asp.net les forums, et tout un tas d'autres. J'ai essayé de réglage de la Publication des déclencheurs et AsyncPostback déclenche, et ce la fin de la nuit, je ne me souviens pas ce que tout le reste. Aucun d'entre eux travaillaient, y compris celui marqué comme réponse sur cette page. Ce que j'ai enfin trouvé était un obscur poste de 2007 sur la asp.net ce forum, qui, pour une raison qui maintenant ne se charge pas sur mon navigateur. En tout cas, ce qui a finalement fonctionné pour moi a été le remplacement de la

<form id="form1" runat="server>

tag avec ceci:

<form id="Form1" method="post" enctype="multipart/form-data" runat="server">

A fonctionné à merveille.

Dans mon cas, c'était dans le Site.Fichier maître, mais dans le cas de l'affichage sur forums.asp.net il a travaillé dans un défaut.fichier aspx.

Mise à jour: L'forums.asp.net le site était en baisse, mais il est de retour maintenant: UpdatePanel + FileUpload + PostBackTrigger ne semble pas fonctionner.
