i know there is a event for "On Delete Row" for each field in the subform. This event seems to get executed in real time as the user interacts with the form.

What I'm looking for is the event when the user finishes changing the subform and hit "Submit" on the main form. That's when data gets persisted for the subform, correct? At that point, i want to compare the previous subform content and the new subform content and send out an email about the changes. Is this possible? If not, any workaround?

Thanks
