Use a custom provider property in dropdown

[Alex]

Hello,
Ive created a custom DB provider in order to assign multiple resources to an appointment. I also have a custom advanced editing form that has a number of drop down lists. each custom dropdown has a corresponding custom attribute.  
I have coded my provider so all of the resources that need to be loaded into the dropdowns are available via properties but I dont know how to hook the two up? 
For example, I have the following property in my custom provider:

    private IDictionary<int, Resource> Locations
    {
        get
        {
            if (_locations == null)
            {
                _locations = new Dictionary<int, Resource>();
                foreach (Resource location in LoadLocations())
                {
                    _locations.Add(Convert.ToInt32(location.Key), location);
                }
            }
            return _locations;
        }
    }

How do I get these locations to populate a dropdown on my Advance Edit form?
Is this the recommended/correct way to do this?

Thanks
Alex
