i have a gridview in that i have checkbox and file upload controls and common submit button outside gridview.
if i checked a row checkbox and i need to check whether the file upload control contains any value or not.
if checkbox is checked and file upload control contains values then i will insert the details into database table.
if not means i will show a message.
if not checked means its not a problem no need to validate the control.
how to do this..
