Dropdown Box Controls - Different In edit and Insert Mode

[Julie3]

I have 2 tables which are related - Clients and ClientContact.

Clients -
ClientID int32
Company varchar
Active bit

ClientContact
ClientID int32
ClientContact varchar

When I use the dropdownlist control on the contact page and set the data source to only show active clients, if the current company is not active it disappears in in edit mode - should I be adding the current value in programmatically or changing the list on insert mode?
