I have a class that will be edited via the CollectionEditor/CollectionForm
UI.  To that extent I have defined the various properties I want editable for
my class.  However, three of the properties are of type string but I would
like them edited by selection from a dropdown list whose contents are
determined at runtime.

It looks like I might be able to use the ICustomTypeDescriptor interface to
do what I need.  In particular, if I could override the GetEditor method to
create a specialized UITypeEditor for these three properties then I think
this would do the trick.

The only problem is that I cannot see how I know, when GetEditor is being
invoked, which property it is being invoked for!

Thanks,
