Based on the given details, I believe that you are discussing Grid sorting capability. In this case, the ComboBox could be an editor in the column, but it does not affect the sorting behavior of the grid, as it is based on the underlying DataSource component.
If this is the case, then you most probably will need to sort by complex objects
. Thus you will be able to edit the 'dataValueField' model property using the ComboBox and still sort by the corresponding 'dataTextField' model field. I would suggest you check the following forum post that discusses the same scenario:
