Hello Mark,
In the LightSwitch demo you have mentioned , you have the source for the grid accessed via the Screen object. Exactly the same way you can get the ItemsSource for the combo box column and set it form code behind ( for example) .
In case you have difficulties implementing this , just send me a LightSwitch project with your data ( or some sample data) , and I will add the missing part with the combo column for you.
