Don't worry your English is fine. To my knowledge there is no other way to
populate a list, no special framework method that will not require what you
are currently doing. The DataSource and DataField properties are used to
associate the list control with a bizobj and allow retrieval of the data.
DataSource and DataField are one of the major features of the Dabo.
Only one gotcha - when retrieving data from the bizobj for the list control
you have to insure all possible values are available in the Choices/Keys.
That would include a None value. Therefore, in the method
"verbesBiz.chargeLtVerbesOc()" you will need to add for a choice "None" and
zero for Keys. This will mostly like occur when dealing with a blank/empty
record/row.
Hope this helps,
