Your collection should have an indexer. I suspect that it doesn't. I usually
write an Add, Remove and an idexer and that seems to work fine.

The objects that you store should be marked as Serializable.

The property that provides the collection should ideally be read-only and be
marked with the DesigerSerializationVisibility attribute using
DesignerSerializationVisibility.Content This will enable the codegenerator
to serialize your ojects.

See Windows Forms Tips and Tricks for an article on how to debug controls at
design time too.
