See the code below which I put in a constructor just to try it. I would suggest you try this also to decide if the property works or if there is an issue with the way you are binding.

Frank,

The binding source is supposed to be set to the business object that contains the EntityList you are binding to. If Agent is that business object, then it appears you have it correct. However, since your binding does not indicate you are synchronizing it to another table foreign key you could just populate the combo. What do you do with the data in the combo once they select a value?
