'Declaration Public Property FilterEvaluationTrigger As FilterEvaluationTrigger
public FilterEvaluationTrigger FilterEvaluationTrigger {get; set;}
Controls when the filters are evalulated whenever the user modifies filter criteria. Default is resolved to OnCellValueChange which evaluates the filter as the user types contents in the filter cell.
This is only applicable to filter record ui (FilterUIType). To control if filters get re-evaluated on a data record if its data changes, use the property.
