RemarksThis class participates in the standard Persistate binding scheme through the SetBindings method. This binding handles automatic population of the combo box in each row in two ways. Firstly, if the bound member is of a multi-value DataClass, then the combo is populated with the appropriate multiple values.
Secondly, if the member is an associated object member with a from clause, then the combo is populated with the appropriate from clause source collection for each member. This can be different for each row in the PGrid.
