I have a gridview which contains a hidden field and a check box. Some of the check boxes will be populated and some not.
Without postback the user will make some changes and click update. when it updates i only want to change the ones that have changed so i have added a hidden field and what i want to do is set the hidden field value to 1 only on those rows where a change is made. I'm thinking this can be done using js but i dont know how?
