The discount criteria are used when creating discounts for selected users and/or roles. The criteria allow you to specify the ID of a user or role that the discount to be applied to. A discount can have more than one discount criteria set assigned to it.
The discount criteria are represented by the Telerik.Sitefinity.Ecommerce.Orders.Model.DiscountCriteria class. The class exposes the following specific properties:
Gets or sets the discount that the criteria set belongs to.
Gets or sets the ID of the role for the criteria.
Gets or sets the ID of the user for the criteria.
NOTE: You must set either the RoleId or the UserId property of the DiscountCriteria instance. If you need to combine users and roles for the discount, create a discount criteria for each requirement.
