Link class inhereting from ListFieldIterator to a document list programatically

Question

Hello All
I need to control the display of certain fields in a list according to the current user.
I implemented it using a class inherited from ListFieldIterator .
now , I want to connect the class i created to the document list, and I need to do it programatically
I created a usercontrol and copied its markup from DefaultTemplates.ascx usercontrols in CONTROLTEMPLATES
but still when I try to debug it does not catach the code.
How can it be done?

I think the proper way to customize list fields based on a specific context (the current user in our case) is to resort to using Custom Field Type Definition.
Using this technique, you can inherit from an existing list field type definition such as SPFieldDateTime, SPFieldMultiColumn, ...etc and then tweak the new field type to match your business.
When you're done implementing the type definition, you can start creating new list/site fields from this custom field type definition.
