Template Repeater & propertyChange events

I have a project that uses 50 copies of the same template… It’s a perfect application for the template repeater but I’m not sure how to get one portion of it working properly.

Right now, I have a custom property on each template that I tie to a common field on the main screen that changes when I need to fire the propertyChange event on the template. This repopulates the templates with some data.

The question is, how can I do this as easily with the repeater? I see that I have a dataset to work with in the repeater, but that makes it look like I’d have to run a script to build a dataset of triggers to make this happen… not nearly as easy as what I am currently doing…

Any thoughts?
