I have an editable data grid driven by an ArrayCollection of value objects that I would like to validate on the fly, row by row. As an invidual column is edited, I'd like to invoke logic to check if the row's VO is 'valid', meaning all data elements are present and within valid ranges and so forth. I'm still thinking through the best approoach.
Currently I'm playing using ChangeWatcher in the VO to watch each property and determine the VO's validity when a property changes. I could loop through the ArrayCollection and check validity of each item but I would need to somehow listen for row level changes to trigger the validation. That just feels kludgey. Has anyone messed around with this? Jeff Battershall Application Architect Dow Jones Indexes [EMAIL PROTECTED] (609) 520-5637 (p) (484) 477-9900 (c)
