I suspect the problem Frank was solving was how to know or compare the value for some other purpose other than or before the mm save was taking place. I don't really know if using a enum made this more complicated or not but he will certainly need to keep his enum values syncrhonized with the table driven values as well because of it.
What I didn't (and still don't) understand is:
(a) Frank says an int is used to store the enum value in the Lookup table.
(b) This table is the DataSource for the combo box.
(c) But..... the SelectedValue of the ComboBox is a string representation of an integer.
(which means that to compare it against any enum value the enum itself has to be converted to an int and then to a string.....)
So why/where did the .SelectedValue become a string ?
In that situation then using an enum is certainly more complicated than it need be......
Anyway, not important since it works and Frank's happy :-}
