Cross-Thread Form Binding - Can it be done?

Cross-thread form binding? It's not a sound idea. The usual way to
deal with this is to use Invoke and CallBacks. There's a good example
at: http://www.codeproject.com/KB/miscct...essdialog.aspx

Are there few enough lines for the code to be posted here?

Oops; minor optimisation (that I prep'd for, then forgot...):

replace:
SynchronizationContext.Current.Send(
with:
ctx.Send(

Because the thread calling the ThreadedBindingList methods may not be the thread that created the list, you will want to move the SyncronizationContext object out of the methods and into a class variable. This way, the sync context will always be the one that created the object:

public class ThreadedBindingList<T: BindingList<T>
{
SynchronizationContext ctx = SynchronizationContext.Current;
protected override void OnAddingNew(AddingNewEventArgs e)
{
//SynchronizationContext ctx = SynchronizationContext.Current;
if (ctx == null)
{ BaseAddingNew(e); }
else
{ ctx.Send(delegate { BaseAddingNew(e); }, null); }
}

void BaseAddingNew(AddingNewEventArgs e)
{ base.OnAddingNew(e); }

protected override void OnListChanged(ListChangedEventArgs e)
{
//SynchronizationContext ctx = SynchronizationContext.Current;
if (ctx == null)
{ BaseListChanged(e); }
else
{ ctx.Send(delegate { BaseListChanged(e); }, null); }
}

void BaseListChanged(ListChangedEventArgs e)
{ base.OnListChanged(e); }
}
