Is it possible to dynamically populate the values in a List for a string type?

is it possible to dynamically populate the values in a list for a

string

type?

just following up on this. Is it possible to populate the values of a list at runtime or can it only be done at build time?

actually, I guess one way around it is if I build a custom component that fetches those values at runtime. That would make more sense.

The built in component can't only do it at build time, but as you say, for dynamic values, a custom component is the way to go. Some resources that might be helpful:
