Validate an item based on the value of another
I have two fields on my application, one that determines the type of record I am creating and another that holds the severity. The severity is only required when a certain type of record is created. So a item level validation item doesn't seem to work since the form is not posted yet and it does not know what type of record it is yet.
Does anyone have any ideas? Ideally I do not want to post the record to the database first.
