I've just published version 2.0 of Lookup Field with Picker.
- Single- and Multiselection
- Search Operators (equals, not equals, contains, begins with, greater...)
- Choose the fields you want to search for
- Delivered as SharePoint Solution Package
Download it from iLove SharePoint.
p.s. Perhaps is just the last code I've ever published, tomorrow I'll be "Game Over" - I'll marry ;-) The next two weeks I'm in honey moon...
