Domains

[PrestonStafford]

I have a existing Attribute in a Feature Class that i'm trying to set a Domain for, but when I click on the fields tab, it will not pull up the Domain List. I have never had a problem doing this with any other feature class. Can anyone tell why or how to fix this?

Domains are a property of a geodatabase: start here:  ArcGIS Help 10.1

My apologies-  I mis-read the original post.  I think Gabreial's comment is the place to start....​

Is the field the proper data type?

Is the feature class in a SDE geodatabase? If yes, make sure there are no Locks on that feature class when you try to assign the Domain.
