Hi Kevin,

Both your problems have an easy solution: just put thisform.cmbMyCombo.DisplayValue='N' (in design time or in Init method of your combobox). It should eliminate empty string and the default value would be 'N'.
Then you can bound your 1 character field to this combobox.

If this field allows only 2 state: Y or N you can try checkbox, as Mike suggested, but you should do some manipulations...
