However we have prepared the work around for firing the Validated event like the below code example, I could not use this workaround (manually calling Set Current Row Validated(false)) because the event Data Grid_Current Cell Value Changed does not fire for Grid Combo Box Column and also not for a Combo Box Adv in a Data Template.
