The deleting is most likely done by a script on the server.

You need a function that loops through the collection of checkboxes and sets them all to checked=true. Something like
for (var i = 0; i < document.forms[0].mychecks.length; i++) {
document.forms[0].mychecks[i].checked = true;
}
I hope this puts you on track.
