UniqueFieldSaveBehavior class

namespace: Serenity.Services assembly: Serenity.Net.Services

Behavior that handles UniqueAttribute on a single field. It checks the unique constraint before save (unless CheckBeforeSave is disabled) by running an existence query. Override BuildUniqueConstraintQuery in a derived behavior, or add your own behavior and set DisableDefaultBehavior on the field, to customize or replace the pre-check.
