Once again thanks for the help, another case of a great solution.

I was also trying to do it the 2005 way

which I think I solved:-

private DataConnector dcTypes = new DataConnector();
dcTypes.DataSource = myTaskType.Types;
comboBox1.DataSource = this.dcTypes;

Which is really exactly the same as you suggestion with another layer of extraction, just like MS what us to use for some reason.
