HTML File Upload Control Problem in Asp.net 2003

hi im using html File Upload Control in Asp.net 2003 version...whenever I try to u开发者_开发技巧pload the file its working fine...but suppose I upload the file then I click any radio button or any other button, fileupload control value is automatically erased..so I cannot upload the file successfully...anybody help me...

As far as I know; fileUpload control does not keep the value for browse during the other controls postbacks, for security reasons.

This may give you a hint.
