In some cases it might make more sense to process each selected item one at a time.

In other words, make a separate server call for each selected item passing the value of the selected item. In some cases the list will need to be processed as a whole, but in some not.

I needed to process a list of selected people and then have the results of the query show up on an existing page beneath the existing data for that person. I initially though of passing the whole list to the server, parsing the list, then passing back the data for all of the patients. I would have then needed to parse the returning data and insert it into the page in each of the appropriate places. Sending the request for the data one person at a time turned out to be much easier. Javascript for getting the selected items is described here: check if checkbox is checked javascript and jQuery for the same is described here: How to check whether a checkbox is checked in jQuery?.
