>Is there anyway when you add a property to a class to make this a layout-prop or a data-prop ?
I think there is no way to change the built-in VFP behavior, namely, that all properties go to "Other".
While you can't change the presentation of the property sheet, you can create your own builder instead. I don't the details of creating builders, but the end result is that you change the properties of your form through another form.
