Today I’ve decided to post a control I created for EXTjs that might be useful to you. The problem I was running into was that I had a group of checkbox controls that all needed to be set based on if a record exist in the database or not. If the record is there, the box should be checked. If it isn’t there, it shouldn’t be checked.
Further, if the user checks a box, it should add a corresponding record into the database.
