Componter binding and schema formatter

[idpexec]

I have some data imported from a dbase into a dataset component. The data contains three fields: firstName, lastName, and id. I'm trying to issolate just the id column data and use it as the dataProvider for a comboBox.

Any clues? I can easily bind the dataProvider of the comboBox to the dataProvider of the dataSet, but each item of the comboBox would contain firstName , lastName , id.

I want to basically filter out the first two fields and only read the id field. Can I do this using the formatter option either under schema or bindings?

Thanks,
Ward
