Maybe I didn't explain the last post clearly(Title: ComboBox ItemRenderer Display Value and Actual Value). Let me change to another description:
It's a common scenario to display a different value in UI from underling database table value. Anyone can tell me how to use datagrid column Itemrenderer to display underling table column data with another intutive/illustrative value? i.e. underling table value is state abbrevation, while displaying full name of the state. Pls. help!
Look at the examples for labelFunction
