Kevin,
Infragistics lists the following:
FIX:BR04618 - UltraCombo as DropDownList throws "Internal error: can't convert to DestinationValue" when setting to a value not in the list

Are there any changes required in the framework for this hotfix? We are experiencing the error that requires the update. Thanks and Good Afternoon,
