Viv,
>In this particular instance, yes, all I really need is to store the relevant int in the table - so if there is a simpler way that's fine. But, in general, is it possible to bind a UI control to a Entity property that is not directly derived from a table field?
Absolutley...all you need is a property and a private field. When doing this though you need to use standard VS 2005 data binding rather than MM .NET data binding.
