Problema con el componente, se activa al cambiar (DataSource.State)

[[José Luis Garcí]]

Buenos días compañeros, tengo un problema con este componente, que es el siguiente, cuando cambia el State de este TDBToggleSwitch, me activa directamente el Datasource.State DsEdit y no se como remediarlo, como siempre espero a vuestras indicaciones y os doy mil gracias como siempre.
