How can i set the selected value in box? e.g. in a "new book" form i need the "language_code" to be preselected to "en" and i use a dblookupcombobox to display language names...

Notes
- I cannot get unbound mode to display any text without setting KeyField (see below) - Mike Thompson 05 June 2014
- If DBLookupCombo.ScrollListDataset is set, then the component will only scroll the dataset when the user interacts with it.
Setting DBLookupCombo.KeyValue in code will not cause the DBLookupCombo to scroll the dataset.
