How do I create custom collections that can be bound to comboboxes?

[Don]

I've been trying to create a custom collection that can be bound to a
combobox via the DataSource property, but I can't seem to get it to work.
I've created a class that implements IList, and it seems to work okay on its
own, but when I try to bind it to a combobox, the combobox doesn't show
anything (and it starts having problems repainting itself). The Datasource
appears to contain my custom collection object, but when I ask for its item
count I receive zero when I should be receiving a higher number.

Has anyone tried to do something like this before and succeeded? Maybe
there's just a problem with my implementation of IList? I can post my code
(it's long) or email it if anyone wants to see it.

Just base your collection on CollectionBase and fill in the appropriate
blanks of Add, Remove and indexer.

Okay, I followed the instructions for creating a class based on
CollectionBase. It now binds to a combobox, but the combobox just shows the
class name instead of the value the ToString property returns for each
object. What's up with that?
