Hi Dadu,

Fileupload doesn't work for updatepanel. I got the same problem once.

1. Without updatepanel - it works fine
2. With updatepanel - you have to use postback trigger like this inside the update panel.
                             
                             
                                 
                             

3. With updatepanel - You can use ASyncFileUploadControl in AJAX.

I do not know but it si not working in my project
If I remove update panel then my code is work perfectly
 

So you meant to say you are using DOtnet framework3.5 and its not working? I tried with dotnet framework 3.5 also, its working.

It is ASP.NET framework 4
if yes
then it is not work in visual studio 2008, which i use

I check that If I remove update panel the works properly but with update panel it is not work yet

check the attachment

I i put asp:FileUplod and button in side the update panel then i am unable to get the file
but if i remove the update panel then i am able to get the file and save it successfully.

I want to use with update panel i see an examples but that also not work in my page

the examples I send with the post
