Multiview + File Upload + UpdatePanel , selected file not upload to server

Recently I have developed some module to upload the file to server. In my code i have Update panel and also the multiview. Somehow the upload not working. So i though i was not set the full postback for upload process in the trigger section under update panel. But actually the full postback was set correctly. So i wonder, why the upload not work. Why server detected that no file submit to server.

So i start investigate my code, and luckily i found the solution.

The solution 

I just need to set enctype attribute at the form and value multipart/form-data .

This is the code i use.

   protected override void OnInit(EventArgs e)  
   {  
     base.OnInit(e);  
     Page.Form.Attributes.Add("enctype", "multipart/form-data");  
   }  

Hopefully this simple solution help someone.
