Problem using Fileupload control within update panel

Hi Jamshaid.Shakoor,

Place FileUpload inside UpdatePanel is not supported because files cannot be uploaded asynchronously.

Refer this document http://ajax.asp.net/docs/mref/T_System_Web_UI_PostBackTrigger.aspx

Hope this helps

Thank you for help dear!!! Now i can understand the problem

there are 2 possibilities if you still want to upload file with ajax:

1. do it with iframe (search with google. i think there so many resources about this)

2. use AsyncFileUpload from www.arindsoft.com just like I did. it's awesome...
