Thanks Adam for replying,
The files have send me still not works.
I am summerizing the problems that i am facing,

1>I cannot save the uploaded file to my desired location,though the file gets saved to a temp folder created by ur tool,i tried with CopyTo() and MoveTo() methods.

2>If i set a breakpoint on
   void Uploader_FileUploaded(object sender, UploaderEventArgs args)

the breakpoint is not catching the event so i cannot see the control flow also i cannot view the event working for me

3>After upload compleates to a temp folder i am getting a weired messege something like "Http error1 1: 12031:Unknown"
i've googled with this and i found i messege means:
 
12031       ERROR_INTERNET_CONNECTION_RESET
               The connection with the server has been reset.
also found this may an error caused by updatepanel[not sure].

plz let me know what is happening...

Thanks
