I have a DataGrid bound to a custom collection that implements
IBindingList. It is well known that updates to windows forms widgets
must be done on the same thread as the form. Here is the kicker: I
would like to have a process in a separate thread that makes updates
to the collection. Ideally what I would like is for the DataGrid to
call Invoke() when it receives the ListChanged event, before updating
itself. Is there a correct way to do this?

I have worked around this issue by implementing my collection as a
derivative of IList, instead of IBindingList so that updates to the
list in a separate thread don't cause a refresh on the DataGrid. What
I do then, is implement a custom ListChanged event on my collection,
and I wrap the DataGrid in a separate component that listens for the
event - calling DataGrid.Refresh() through an Invoke.

This works great, however, the 'whole' Data grid gets refreshed every
time a single row changes, which causes a bit of flicker.

Any thoughts on how to properly update an IBindingList in a separate
thread? This seems like an obvious thing to need to do...

Cheers,
