Hi,
I would like to enhance my application to support custom field for certain customization without need to change my core project (may be with certain extension). Anyone can provide some ideas?

I was thinking to use plug-in approach to achieve it. However, It seem a bit complicated:-

1. How to rearrange all controls if I need to position some of the custom field at middle of standard fields?

2. Require to re-assign tab order at runtime based on logic.

3. If I would like to place my custom field at separate table, how could I guarantee uniqueness?

4. Too many possible event I need to be handled (such as CRUD, valid, lost focus and etc) at my plugin.

and etc.

Any ideas?

Thank you
