To maintain the consistent UI, customer have the requirement to display the Aggregate row event when the Grid dataSoure is having empty records.
we have logged this as a improvement feature and we need to implement this by using the below way.Case 1) If the Grid records is empty at this time the aggregate will not displayed. We need to maintain our default behavior.
Case 2) If customer like to display the aggregates when the Grid records is empty, need to create and trigger an event before rendering the aggregate. In this event, we can set the arguments as true when the Grid records are empty and based on this we need to show the Aggregate row in the Grid.
