I am developing a custom list definition within Visual Studio 2010 for SharePoint 2010, I have ran into a problem with adding a field which will be choice and will use items from another list on the SharePoint site.
I have attempted searching and have only found references to a static list of choices within the list definition schema.
I would imagine a similar approach would also be used for Radio Groups which is another field requirement I have for this list.
If anyone can provide examples or point me to a place which I can find this out I would greatly appreciate it.
