By failing I mean that the combobox displays nothing - although the debugger says that the Value *and* DisplayValue properties are what they should be. Forcing a form Refresh doesn’t seem to help.

Two ideas.

1. Try a thisform.cboMainLite.requery in the lost focus of the combobox
2. If based on a sql, do you need the combobox style or is list style for the combo box more correct. Tab works much better with the style set to list. If you need to add new items to the list then you'll need special code.
