You must be having text boxes and checkboxes in the row.
When you send it to the server, an array of the each of the objects is created. For checkbox there will be an array.
Hopefully when you submit the page, the array gets sent.
You then do a
request.getParameterValues("THE_CONTROL_NAME")
and get it in a
string array.
Then use the string array to update in the Database.
Hope this helps
