Hello Denis,
I would recommend you to use
RadODataDataSource as data source for populating your
RadComboBox control. Easy and convenient way would be use the design time wizard to set the populating schema for your
ComboBox. Please find
here some more information about
RadODataDatasource and an
sample demonstration for populating
RadComboBox using
RadODataDataSouce.
Hope that this will lead you into right direction.
Regards,
Boyan Dimitrov
